+I have added a few new configuration files to the configs directory:
+
+    There's a base configuration, debian, which sets things up for
+    building in a debian environment.
+
+    There's also a debian-static configuration, which is for static
+    building.
+
+All the others are derived from one of these two configurations.
+
+The platform-specific optimizations go into a debian-foo_ARCH file, like
+debian_i386 or debian_sparc.  You can name this files whatever you want,
+but the last token must be a debian arch name.  Note the "_"!  These
+will be picked up automatically by the debian/rules.
+
+In order to actually install the new files, you need to edit
+debian/libdir.map, the format is:
+
+    target-name libdir package package-dev
+
+The architecture optimized libraries should go under
+/usr/lib/<something>, where <something> matches the optimizations used,
+e.g. "mmx" or "v9".
+
+Only packages listed in the control file *and* libdir.map are actually
+built.  That means that even if debian/libdir.map lists
+libgl1-random-stuff, if libgl1-random-stuff is *not* listed in
+debian/control it *won't* be built.  The other way around, if
+libgl1-random-stuff is listed in debian/control but there's no entry for
+it in debian/libdir.map it *won't* be built.
+
+For architectures where glide3 is available an extra package is built
+(iff this is the mesa-legacy source package).  The list of supported
+architectures in found in the control file.
+
+There's an alioth project for this package:

+mesa (6.4.1-1) unstable; urgency=low
+
+  [ Marcelo E. Magallon <mmagallo@debian.org> ]
+  * debian/control: build-depend on xutils (closes: #326466)
+  * include/GL/glx{int,proto,md,tokens}.h: missing upstream (closes: bug#326466)
+  * debian/libgl1-mesa-dri-dev.install: install GLX include files here, too.
+  * debian/rules: GLU and GLW don't have arch-specific targets.
+
+  [ Daniel Stone <daniels@debian.org> ]
+  * New upstream version, incorporating changes from Ubuntu 6.3 packaging.
+  * Rename packages:
+    - mesag3 -> libgl1-mesa-swrast
+    - mesag-dev -> libgl1-mesa-swrast-dev
+    - libgl1-mesa-dri -> libgl1-mesa
+    - libgl1-mesa-dri-dev -> libgl1-mesa-dev
+    - libgl1-mesa-dri still exists, but now contains the DRI modules only.
+  * Drop dependency *from* mesa-common-dev on libgl1-mesa-dev and
+    libglu1-mesa-dev; it should be the other way around.
+  * Add Build-Depends on pkg-config to get flags from libdrm, and libexpat-dev
+    for DRI configuration.  Break out xlibs-dev Build-Depends to the
+    individual libraries required.
+  * Bump libdrm-dev Build-Depends to >> 1.0.5, in order to get new
+    via_drm.h to build the unichrome DRI driver.
+  * Configs: pare DRI drivers down to a sensible set for each architecture.
+  * Remove completely broken Glide target, which caused FTBFS.
+  * Add mesa-swrast-source package, providing the source for the software
+    rasteriser for libGLcore in the X server.
+  * Drop tight libosmesa6 -> libgl1-mesa-swrast Depends, replace with
+    shlibs:Depends.
+
+  [ David Nusinow <dnusinow@debian.org> ]
+  * New upstream version (6.4.1)
+  * Merge changes from Ubuntu version 6.4.1-0ubuntu1
+    + Add new files required by xorg-server GL build to mesa-swrast-source.

+Description: A free implementation of the OpenGL API -- runtime
+ Mesa is a 3-D graphics library with an API which is very similar to
+ that of OpenGL.  To the extent that Mesa utilizes the OpenGL command
+ syntax or state machine, it is being used with authorization from
+ Silicon Graphics, Inc.  However, the author makes no claim that Mesa
+ is in any way a compatible replacement for OpenGL or associated with
+ Silicon Graphics, Inc.
+ .
+ This library provides a pure software rasteriser; it does not provide
+ a direct rendering-capable library, or one which uses GLX.  For that,
+ please see libgl1-mesa.
+ .
+ On Linux, this library is also known as libGL or libGL.so.1.

+ provided mainly for modular X servers which support GL, and need the
+ software rasteriser source to build the GLcore module for unaccelerated
+ indirect rendering.

+
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

+    OpenGL 1.0 or later is required
+    This extensions is written against the OpenGL 1.4 Specification.
+
+Overview
+
+    This extension adds a new pixel storage parameter to indicate that
+    images are to be packed in top-to-bottom order instead of OpenGL's
+    conventional bottom-to-top order.  Only pixel packing can be
+    inverted (i.e. for glReadPixels, glGetTexImage, glGetConvolutionFilter,
+    etc).
+
+    Almost all known image file formats store images in top-to-bottom
+    order.  As it is, OpenGL reads images from the frame buffer in
+    bottom-to-top order.  Thus, images usually have to be inverted before
+    writing them to a file with image I/O libraries.  This extension
+    allows images to be read such that inverting isn't needed.
+
+IP Status
+
+    None
+
+Issues
+
+    1. Should we also defined UNPACK_INVERT_MESA for glDrawPixels, etc?
+
+    Resolved:  No, we're only concerned with pixel packing.  There are other
+    solutions for inverting images when using glDrawPixels (negative Y pixel
+    zoom) or glTexImage (invert the vertex T coordinates).  It would be easy
+    enough to define a complementary extension for pixel packing in the
+    future if needed.

+Overview
+	
+    Provides a mechanism for DrawPixels and ReadPixels to efficiently

+    into one value.
+
+Issues:
+
+    1. Is this the right way to distinguish between 24/8 and 8/24
+       pixel formats?  Should we instead provide both:
+	
+       GL_DEPTH_STENCIL_MESA
+       GL_STENCIL_DEPTH_MESA
+
+       And perhaps just use GL_UNSIGNED_INT, GL_UNSIGNED_SHORT ?
+
+    2. If not, is it correct to use _REV to indicate that stencil
+       preceeds depth in the 1_15 and 8_24 formats?
+
+    3. Do we really want the GL_UNSIGNED_SHORT formats?

+
+Overview
+
+    Since Mesa allows RGB rendering into drawables with PseudoColor,
+    StaticColor, GrayScale and StaticGray visuals, Mesa needs a colormap
+    in order to compute pixel values during rendering.
+
+    The colormap associated with a window can be queried with normal
+    Xlib functions but there is no colormap associated with pixmaps.
+
+    The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap
+    which allows specification of a colormap.

+
+    The Mesa implementation of GLX allows RGB rendering into X windows and

+    to compute pixel values from RGB values Mesa requires a colormap.
+
+    The function
+
+	GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
+					  Pixmap pixmap, Colormap cmap );
+
+    allows one to create a GLXPixmap with a specific colormap.  The image
+    rendered into the pixmap may then be copied to a window (which uses the
+    same colormap and visual) with the expected results.

+
+    OpenGL 1.4 is required
+    The extension is written against the OpenGL 1.4 specification.
+    ARB_vertex_program or ARB_fragment_program or NV_vertex_program
+    or NV_fragment_program is required.
+
+Overview
+
+    The extension provides facilities for implementing debuggers for
+    vertex and fragment programs.
+
+    The concept is that vertex and fragment program debuggers will be
+    implemented outside of the GL as a utility package.  This extension
+    only provides the minimal hooks required to implement a debugger.
+
+    There are facilities to do the following:
+    1. Have the GL call a user-specified function prior to executing
+       each vertex or fragment instruction.
+    2. Query the current program string's execution position.
+    3. Query the current values of intermediate program values.
+
+    The main feature is the ProgramCallbackMESA function.  It allows the
+    user to register a callback function with the GL.  The callback will
+    be called prior to executing each vertex or fragment program instruction.
+
+    From within the callback, the user may issue Get* commands to
+    query current GL state.  The GetProgramRegisterfvMESA function allows
+    current program values to be queried (such as temporaries, input
+    attributes, and result registers).
+
+    There are flags for enabling/disabling the program callbacks.
+
+    The current execution position (as an offset from the start of the
+    program string) can be queried with
+    GetIntegerv(GL_FRAGMENT_PROGRAM_POSITION_MESA, &pos) or
+    GetIntegerv(GL_VERTEX_PROGRAM_POSITION_MESA, &pos).
+
+
+IP Status
+
+    None
+
+Issues
+
+    1. Is this the right model for a debugger?
+
+       It seems prudent to minimize the scope of this extension and leave
+       it up to the developer (or developer community) to write debuggers
+       that layer on top of this extension.
+
+       If the debugger were fully implemented within the GL it's not
+       clear how terminal and GUI-based interfaces would work, for
+       example.
+
+    2. There aren't any other extensions that register callbacks with
+       the GL.  Isn't there another solution?
+
+       If we want to be able to single-step through vertex/fragment
+       programs I don't see another way to do it.
+
+    3. How do we prevent the user from doing something crazy in the
+       callback function, like trying to call glBegin (leading to
+       recursion)?
+
+       The rule is that the callback function can only issue glGet*()
+       functions and no other GL commands.  It could be difficult to
+       enforce this, however.  Therefore, calling any non-get GL
+       command from within the callback will result in undefined
+       results.    
+
+    4. Is this extension amenable to hardware implementation?
+
+       Hopefully, but if not, the GL implementation will have to fall
+       back to a software path when debugging.  This may be acceptable
+       for debugging.
+
+    5. What's the <data> parameter to ProgramCallbackMESA for?
+
+       It's a common programming practice to associate a user-supplied
+       value with callback functions.
+
+    6. Debuggers often allow one to modify intermediate program values,
+       then continue.  Does this extension support that?
+
+       No.

+
+    In section 5.4 "Display Lists", page 202, add the following command
+    to the list of those that are not compiled into display lists:
+
+        ProgramCallbackMESA.
+
+
+    Add a new section 5.7 "Callback Functions"
+
+    The function
+
+        void ProgramCallbackMESA(enum target, programcallbackMESA callback,
+                                 void *data)
+
+    registers a user-defined callback function with the GL.  <target>
+    may be FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB.  The enabled
+    callback functions registered with these targets will be called
+    prior to executing each instruction in the current fragment or
+    vertex program, respectively.  The callbacks are enabled and
+    disabled by calling Enable or Disable with <cap>
+    FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB.
+
+    The callback function's signature must match the typedef
+
+        typedef void (*programcallbackMESA)(enum target, void *data)
+
+    When the callback function is called, <target> will either be
+    FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB to indicate which
+    program is currently executing and <data> will be the value
+    specified when ProgramCallbackMESA was called.
+
+    From within the callback function, only the following GL commands
+    may be called:
+
+        GetBooleanv
+        GetDoublev
+        GetFloatv
+        GetIntegerv
+        GetProgramLocalParameter

+        GetProgramRegisterfvMESA
+        GetProgramivARB
+        GetProgramStringARB
+        GetError
+
+    Calling any other command from within the callback results in
+    undefined behaviour.
+
+
+Additions to Chapter 6 of the OpenGL 1.4 Specification (State and
+State Requests)
+
+    Add a new section 6.1.3 "Program Value Queries":
+
+    The command
+
+        void GetProgramRegisterfvMESA(enum target, sizei len,
+                                      const ubyte *registerName,
+                                      float *v)
+        
+    Is used to query the value of program variables and registers
+    during program execution.  GetProgramRegisterfvMESA may only be
+    called from within a callback function registered with
+    ProgramCallbackMESA.
+
+    <registerName> and <len> specify the name a variable, input
+    attribute, temporary, or result register in the program string.
+    The current value of the named variable is returned as four
+    values in <v>.  If <name> doesn't exist in the program string,
+    the error INVALID_OPERATION is generated.

+Dependencies on NV_vertex_program and NV_fragment_program
+
+    If NV_vertex_program and/or NV_fragment_program are supported,
+    vertex and/or fragment programs defined by those extensions may
+    be debugged as well.  Register queries will use the syntax used
+    by those extensions (i.e. "v[X]" to query vertex attributes,
+    "o[X]" for vertex outputs, etc.)
+
+Errors
+
+    INVALID_OPERATION is generated if ProgramCallbackMESA is called
+    between Begin and End.
+
+    INVALID_ENUM is generated by ProgramCallbackMESA if <target> is not
+    a supported vertex or fragment program type.
+
+    Note: INVALID_OPERAION IS NOT generated by GetProgramRegisterfvMESA,
+    GetBooleanv, GetDoublev, GetFloatv, or GetIntegerv if called between
+    Begin and End when a vertex or fragment program is currently executing.
+
+    INVALID_ENUM is generated by ProgramCallbackMESA,
+    GetProgramRegisterfvMESA if <target> is not a program target supported
+    by ARB_vertex_program, ARB_fragment_program (or NV_vertex_program or
+    NV_fragment_program).
+
+    INVALID_VALUE is generated by GetProgramRegisterfvMESA if <registerName>
+    does not name a known program register or variable.
+
+    INVALID_OPERATION is generated by GetProgramRegisterfvMESA when a
+    register query is attempted for a program target that's not currently
+    being executed.

+    Mesa 2.2 or later is required.
+
+Overview
+
+    Mesa is often used as a client library with no integration with
+    the computer's window system (an X server, for example).  And since
+    Mesa does not have an event loop nor window system callbacks, it
+    cannot properly respond to window system events.  In particular,
+    Mesa cannot automatically detect when a window has been resized.
+
+    Mesa's glViewport command queries the current window size and updates
+    its internal data structors accordingly.  This normally works fine
+    since most applications call glViewport in responce to window size
+    changes.
+
+    In some situations, however, the application may not call glViewport
+    when a window size changes but would still like Mesa to adjust to
+    the new window size.  This extension exports a new function to solve
+    this problem.

+Additions to the OpenGL Specification (no particular section)

+    reallocating depth, stencil, alpha and accumulation buffers.

+
+Overview
+	
+    This extension modifies the way in which points are rendered,
+    specifically when they're textured.  When SPRITE_POINT_MESA is enabled
+    a point is rendered as if it were a quadrilateral with unique texture
+    coordinates at each vertex.  This extension effectively turns points
+    into sprites which may be rendered more easily and quickly than using
+    conventional textured quadrilaterals.
+
+    When using point size > 1 or attenuated points this extension is an
+    effective way to render many small sprite images for particle systems
+    or other effects.
+
+Issues:
+
+    1. How are the texture coordinates computed?
+
+       The lower-left corner has texture coordinate (0,0,r,q).
+       The lower-right, (1,0,r,q).  The upper-right, (1,1,r,q).
+       The upper-left, (0,1,r,q).
+
+    2. What about texgen and texture matrices?
+
+       Texgen and the texture matrix have no effect on the point's s and t
+       texture coordinates.  The r and q coordinates may have been computed
+       by texgen or the texture matrix.  Note that with a 3D texture and/or
+       texgen that the r coordinate could be used to select a slice in the
+       3D texture.
+
+    3. What about point smoothing?
+
+       When point smoothing is enabled, a triangle fan could be rendered
+       to approximate a circular point.  This could be problematic to
+       define and implement so POINT_SMOOTH is ignored when drawing sprite
+       points.
+
+       Smoothed points can be approximated by using an appropriate texture
+       images, alpha testing and blending.
+
+       POLYGON_SMOOTH does effect the rendering of the quadrilateral, however.
+
+    4. What about sprite rotation?
+
+       There is none.  Sprite points are always rendered as window-aligned
+       squares.  One could define rotated texture images if desired.  A 3D
+       texture and appropriate texture r coordinates could be used to
+       effectively specify image rotation per point.
+
+    5. What about POLYGON_MODE?
+
+       POLYGON_MODE does not effect the rasterization of the quadrilateral.
+
+    6. What about POLYGON_CULL?
+
+       TBD.  Polygon culling is normally specified and implemented in the
+       transformation stage of OpenGL.  However, some rasterization hardware
+       implements it later during triangle setup.
+
+       Polygon culling wouldn't be useful for sprite points since the
+       quadrilaterals are always defined in counter-clockwise order in
+       window space.  For that reason, polygon culling should probably be
+       ignored.
+
+    7. Should sprite points be alpha-attenuated if their size is below the
+       point parameter's threshold size?
+
+    8. Should there be an advertisized maximum sprite point size?
+
+       No.  Since we're rendering the point as a quadrilateral there's no
+       need to limit the size.

+
+    When SPRITE_POINT_MESA is enabled points are rasterized as screen-
+    aligned quadrilaterals.  If the four vertices of the quadrilateral
+    are labeled A, B, C, and D, starting at the lower-left corner and moving
+    counter-clockwise around the quadrilateral, then the vertex and
+    texture coordinates are computed as follows:
+
+      vertex   window coordinate       texture coordinate
+        A      (x-r, y-r, z, w)          (0, 0, r, q)
+        B      (x+r, y-r, z, w)          (1, 0, r, q)
+        C      (x+r, y+r, z, w)          (1, 1, r, q)
+        D      (x-r, y+r, z, w)          (0, 1, r, q)
+
+    where x, y, z, w are the point's window coordinates, r and q are the
+    point's 3rd and 4th texture coordinates  and r is half the point's
+    size.  The other vertex attributes (such as the color and fog coordinate)
+    are simply duplicated from the original point vertex.
+
+    Point size may either be specified with PointSize or computed
+    according to the EXT_point_parameters extension.
+
+    The new texture coordinates are not effected by texgen or the texture
+    matrix.  Note, however, that the texture r and q coordinates are passed
+    unchanged and may have been computed with texgen and/or the texture
+    matrix.
+
+    If multiple texture units are present the same texture coordinate is
+    used for all texture units.
+
+    The point is then rendered as if it were a quadrilateral using the
+    normal point sampling rules.  POLYGON_MODE does not effect the
+    rasterization of the quadrilateral but POLYGON_SMOOTH does.
+
+    POINT_SMOOTH has no effect when SPRITE_POINT_MESA is enabled.

+
+    glXSwapIntervalMESA specifies the minimum number of video frame periods
+    per buffer swap.  (e.g. a value of two means that the color buffers
+    will be swapped at most every other video frame.)  A return value
+    of zero indicates success; otherwise an error occurred.  The interval
+    takes effect when glXSwapBuffers is first called subsequent to the
+    glXSwapIntervalMESA call.
+
+    A video frame period is the time required by the monitor to display a 
+    full frame of video data.  In the case of an interlaced monitor,
+    this is typically the time required to display both the even and odd 
+    fields of a frame of video data.
+
+    If <interval> is set to a value of 0, buffer swaps are not synchron-
+    ized to a video frame.  The <interval> value is silently clamped to
+    the maximum implementation-dependent value supported before being
+    stored.
+
+    The swap interval is not part of the render context state.  It cannot
+    be pushed or popped.  The current swap interval for the window
+    associated with the current context can be obtained by calling
+    glXGetSwapIntervalMESA.  The default swap interval is 0.
+
+    On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
+    the swap interval to 1.
+
+Errors
+
+    glXSwapIntervalMESA returns GLX_BAD_VALUE if parameter <interval> is

+
+    Based on WGL_I3D_swap_frame_usage version 1.3.
+
+Overview
+
+    This extension allows an application to deterine what portion of the
+    swap period has elapsed since the last swap operation completed.  The
+    "usage" value is a floating point value on the range [0,max] which is
+    calculated as follows:
+
+                              td
+                   percent = ----
+                              tf
+
+    where td is the time measured from the last completed buffer swap (or
+    call to enable the statistic) to when the next buffer swap completes, tf
+    is the entire time for a frame which may be multiple screen refreshes
+    depending on the swap interval as set by the GLX_SGI_swap_control or
+    GLX_OML_sync_control extensions. 
+
+    The value, percent, indicates the amount of time spent between the
+    completion of the two swaps.  If the value is in the range [0,1], the
+    buffer swap occurred within the time period required to maintain a
+    constant frame rate.  If the value is in the range (1,max], a constant
+    frame rate was not achieved.  The value indicates the number of frames
+    required to draw.
+
+    This definition of "percent" differs slightly from
+    WGL_I3D_swap_frame_usage.  In WGL_I3D_swap_frame_usage, the measurement
+    is taken from the completion of one swap to the issuance of the next.
+    This representation may not be as useful as measuring between
+    completions, as a significant amount of time may pass between the
+    issuance of a swap and the swap actually occuring.
+
+    There is also a mechanism to determine whether a frame swap was
+    missed.

+
+    The frame usage is measured as the percentage of the swap period elapsed
+    between two buffer-swap operations being commited.  In unextened GLX the
+    swap period is the vertical refresh time.  If SGI_swap_control or
+    MESA_swap_control are supported, the swap period is the vertical refresh
+    time multiplied by the swap interval (or one if the swap interval is set
+    to zero).
+    
+    If OML_sync_control is supported, the swap period is the vertical
+    refresh time multiplied by the divisor parameter to
+    glXSwapBuffersMscOML.  The frame usage in this case is less than 1.0 if
+    the swap is commited before target_msc, and is greater than or equal to
+    1.0 otherwise.  The actual usage value is based on the divisor and is
+    never less than 0.0.
+
+       int glXBeginFrameTrackingMESA(Display *dpy,
+                                     GLXDrawable drawable,
+				     float *usage)
+
+    glXGetFrameUsageMESA returns a floating-point value in <usage>
+    that represents the current swap usage, as defined above.
+
+    Missed frame swaps can be tracked by calling the following function:
+
+       int glXBeginFrameTrackingMESA(Display *dpy,
+                                     GLXDrawable drawable)
+
+    glXBeginFrameTrackingMESA resets a "missed frame" count and
+    synchronizes with the next frame vertical sync before it returns.
+    If a swap is missed based in the rate control specified by the
+    <interval> set by glXSwapIntervalSGI or the default swap of once
+    per frame, the missed frame count is incremented.
+
+    The current missed frame count and total number of swaps since
+    the last call to glXBeginFrameTrackingMESA can be obtained by
+    callling the following function:
+
+       int glXQueryFrameTrackingMESA(Display *dpy,
+                                     GLXDrawable drawable,
+				     int64_t *swapCount,
+                                     int64_t *missedFrames,
+                                     float *lastMissedUsage)
+
+    The location pointed to by <swapCount> will be updated with the
+    number of swaps that have been commited.  This value may not match the
+    number of swaps that have been requested since swaps may be
+    queued by the implementation.  This function can be called at any
+    time and does not synchronize to vertical blank.
+
+    The location pointed to by <missedFrames> will contain the number
+    swaps that missed the specified frame.  The frame usage for the
+    last missed frame is returned in the location pointed to by
+    <lastMissedUsage>.
+
+    Frame tracking is disabled by calling the function
+
+       int glXEndFrameTrackingMESA(Display *dpy,
+                                   GLXDrawable drawable)
+
+    This function will not return until all swaps have occurred.  The
+    application can call glXQueryFrameTrackingMESA for a final swap and
+    missed frame count.
+
+    If these functions are succesful, zero is returned.  If the context
+    associated with dpy and drawable is not a direct context,
+    GLX_BAD_CONTEXT is returned.
+
+Errors
+
+    If the function succeeds, zero is returned.  If the function
+    fails, one of the following error codes is returned:
+
+       GLX_BAD_CONTEXT         The current rendering context is not a direct
+       			       context.

+
+    OpenGL 1.2 is required.
+    The extension is written against the OpenGL 1.2 Specification
+
+Overview
+
+    Provides the application with means to enable and disable logging
+    of GL calls including parameters as readable text. The verbosity
+    of the generated log can be controlled. The resulting logs are
+    valid (but possibly incomplete) C code and can be compiled and 
+    linked for standalone test programs. The set of calls and the 
+    amount of static data that is logged can be controlled at runtime. 
+    The application can add comments and enable or disable tracing of GL 
+    operations at any time. The data flow from the application to GL
+    and back is unaffected except for timing.
+
+    Application-side implementation of these features raises namespace
+    and linkage issues. In the driver dispatch table a simple
+    "chain of responsibility" pattern (aka "composable piepline")
+    can be added.
+
+IP Status
+
+    The extension spec is in the public domain.  The current implementation
+    in Mesa is covered by Mesa's XFree86-style copyright by the authors above.
+    This extension is partially inspired by the Quake2 QGL wrapper.
+
+Issues
+
+ 
+    (1) Is this Extension obsolete because it can
+    be implemented as a wrapper DLL?
+
+      RESOLVED: No. While certain operating systems (Win32) provide linkers 
+      that facilitate this kind of solution, other operating systems
+      (Linux) do not support hierarchical linking, so a wrapper solution
+      would result in symbol collisions.
+      Further, IHV's might have builtin support for tracing GL execution 
+      that enjoys privileged access, or that they do not wish to separate
+      the tracing code from their driver code base.
+
+    (2) Should the Trace API explicitely support the notion of "frames? 
+    This would require hooking into glXSwapBuffers calls as well.
+
+      RESOLVED: No. The application can use NewTraceMESA/EndTraceMESA
+      and TraceComment along with external parsing tools to split the 
+      trace into frames, in whatever way considered adequate.
+
+    (2a) Should GLX calls be traced?
+
+      PBuffers and other render-to-texture solutions demonstrate that
+      context level commands beyond SwapBuffers might have to be
+      traced. The GL DLL exports the entry points, so this would not
+      be out of the question. 
+
+    (3) Should the specification mandate the actual output format?
+
+      RESOLVED: No. It is sufficient to guarantee that all data and commands 
+      will be traced as requested by Enable/DisableTraceMESA, in the order
+      encountered. Whether the resulting trace is available as a readable 
+      text file, binary metafile, compilable source code, much less which 
+      indentation and formatting has been used, is up to the implementation. 
+      For the same reason this specification does not enforce or prohibit
+      additional information added to the trace (statistics, profiling/timing, 
+      warnings on possible error conditions).
+
+    (4) Should the comment strings associated with names and pointer (ranges) 
+    be considered persistent state?
+
+      RESOLVED: No. The implementation is not forced to use this information 
+      on subsequent occurences of name/pointer, and is free to consider it 
+      transient state.
+ 
+    (5) Should comment commands be prohibited between Begin/End?
+
+      RESOLVED: Yes, with the exception of TraceCommentMESA. TraceCommentMESA 
+      is transient, the other commands might cause storage of persistent
+      data in the context. There is no need to have the ability mark names 
+      or pointers between Begin and End.

+
+Additions to Chapter 5 of the OpenGL 1.2.1 Specification (Special Functions)
+
+    Add a new section:
+
+    5.7 Tracing
+
+    The tracing facility is used to record the execution of a GL program
+    to a human-readable log.  The log appears as a sequence of GL commands
+    using C syntax.  The primary intention of tracing is to aid in program
+    debugging.
+
+    A trace is started with the command
+
+      void NewTraceMESA( bitfield mask, const GLubyte * traceName )
+
+    <mask> may be any value accepted by PushAttrib and specifies a set of
+    attribute groups.  The state values included in those attribute groups
+    is written to the trace as a sequence of GL commands.
+
+    <traceName> specifies a name or label for the trace.  It is expected
+    that <traceName> will be interpreted as a filename in most implementations.
+
+    A trace is ended by calling the command
+
+      void EndTraceMESA( void )
+
+    It is illegal to call NewTraceMESA or EndTraceMESA between Begin and End. 
+
+    The commands
+
+      void EnableTraceMESA( bitfield mask )
+      void DisableTraceMESA( bitfield mask )
+
+    enable or disable tracing of different classes of GL commands.
+    <mask> may be the union of any of TRACE_OPERATIONS_BIT_MESA,
+    TRACE_PRIMITIVES_BIT_MESA, TRACE_ARRAYS_BIT_MESA, TRACE_TEXTURES_BIT_MESA,
+    and TRACE_PIXELS_BIT_MESA.  The special token TRACE_ALL_BITS_MESA
+    indicates all classes of commands are to be logged.
+
+    TRACE_OPERATIONS_BIT_MESA controls logging of all commands outside of
+    Begin/End, including Begin/End.
+  
+    TRACE_PRIMITIVES_BIT_MESA controls logging of all commands inside of
+    Begin/End, including Begin/End.
+ 
+    TRACE_ARRAYS_BIT_MESA controls logging of VertexPointer, NormalPointer,
+    ColorPointer, IndexPointer, TexCoordPointer and EdgeFlagPointer commands.
+
+    TRACE_TEXTURES_BIT_MESA controls logging of texture data dereferenced by
+    TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and
+    TexSubImage3D commands.
+
+    TRACE_PIXELS_BIT_MESA controls logging of image data dereferenced by
+    Bitmap and DrawPixels commands.
+
+    TRACE_ERRORS_BIT_MESA controls logging of all errors. If this bit is 
+    set, GetError will be executed whereever applicable, and the result will 
+    be added to the trace as a comment. The error returns are cached and 
+    returned to the application on its GetError calls. If the user does not 
+    wish the additional GetError calls to be performed, this bit should not
+    be set.
+    
+    The command
+
+      void TraceCommentMESA( const ubyte* comment )
+
+    immediately adds the <comment> string to the trace output, surrounded
+    by C-style comment delimiters.
+
+    The commands
+
+      void TraceTextureMESA( uint name, const ubyte* comment )
+      void TraceListMESA( uint name, const ubyte* comment )
+
+    associates <comment> with the texture object or display list specified
+    by <name>.  Logged commands which reference the named texture object or
+    display list will be annotated with <comment>.  If IsTexture(name) or
+    IsList(name) fail (respectively) the command is quietly ignored.
+
+    The commands
+
+      void TracePointerMESA( void* pointer, const ubyte* comment )
+
+      void TracePointerRangeMESA( const void* first, 
+                                  const void* last,
+                                  const ubyte* comment ) 
+
+    associate <comment> with the address specified by <pointer> or with
+    a range of addresses specified by <first> through <last>.
+    Any logged commands which reference <pointer> or an address between
+    <first> and <last> will be annotated with <comment>.
+
+    The command
+
+      void TraceAssertAttribMESA( bitfield attribMask )
+
+    will add GL state queries and assertion statements to the log to
+    confirm that the current state at the time TraceAssertAttrib is
+    executed matches the current state when the trace log is executed
+    in the future.
+
+    <attribMask> is any value accepted by PushAttrib and specifies
+    the groups of state variables which are to be asserted.
+
+    The commands NewTraceMESA, EndTraceMESA, EnableTraceMESA, DisableTraceMESA,
+    TraceAssertAttribMESA, TraceCommentMESA, TraceTextureMESA, TraceListMESA, 
+    TracePointerMESA and TracePointerRangeMESA are not compiled into display lists.
+
+
+    Examples:
+
+    The command NewTraceMESA(DEPTH_BUFFER_BIT, "log") will query the state
+    variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
+    to get the values <test>, <func>, <mask>, and <clear> respectively.
+    Statements equivalent to the following will then be logged:
+
+       glEnable(GL_DEPTH_TEST);   (if <test> is true)
+       glDisable(GL_DEPTH_TEST);  (if <test> is false)
+       glDepthFunc(<func>); 
+       glDepthMask(<mask>);
+       glClearDepth(<clear>);
+   
+
+    The command TraceAssertAttribMESA(DEPTH_BUFFER_BIT) will query the state
+    variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
+    to get the values <test>, <func>, <mask>, and <clear> respectively.
+    The resulting trace might then look will like this:
+
+    {
+      GLboolean b;
+      GLint i;
+      GLfloat f;
+      b = glIsEnabled(GL_DEPTH_TEST);
+      assert(b == <test>);
+      glGetIntegerv(GL_DEPTH_FUNC, &i);
+      assert(i == <func>);
+      glGetIntegerv(GL_DEPTH_MASK, &i);
+      assert(i == <mask>);
+      glGetFloatv(GL_DEPTH_CLEAR_VALUE, &f);
+      assert(f == <clear>);
+    }
+
+
+Additions to Chapter 6 of the OpenGL 1.2.1 Specification 
+    (State and State Requests)
+
+    Querying TRACE_MASK_MESA with GetIntegerv, GetFloatv, GetBooleanv or
+    GetDoublev returns the current command class trace mask.
+
+    Querying TRACE_NAME_MESA with GetString returns the current trace name.
+
+
+Additions to Appendix A of the OpenGL 1.2.1 Specification (Invariance)
+
+    The MESA_trace extension can be used in a way that does not affect data 
+    flow from application to OpenGL, as well as data flow from OpenGL to 
+    application, except for timing, possible print I/O. TRACE_ERRORS_BIT_MESA
+    will add additional GetError queries. Setting a trace mask with NewTraceMESA
+    as well as use of TraceAssertAttribMESA might cause additional state queries.
+    With the possible exception of performance, OpenGL rendering should not be
+    affected at all by a properly chosen logging operation.
+
+Additions to the AGL/GLX/WGL Specifications
+
+    None.
+
+GLX Protocol
+
+    None. The logging operation is carried out client-side, by exporting

+
+Errors
+

+    is called between Begin and End.
+

+    OpenGL 1.0 is required.
+    The extension is written against the OpenGL 1.2 Specification
+
+Overview
+
+    In order to set the current raster position to a specific window
+    coordinate with the RasterPos command, the modelview matrix, projection
+    matrix and viewport must be set very carefully.  Furthermore, if the
+    desired window coordinate is outside of the window's bounds one must
+    rely on a subtle side-effect of the Bitmap command in order to circumvent
+    frustum clipping.
+
+    This extension provides a set of functions to directly set the
+    current raster position, bypassing the modelview matrix, the
+    projection matrix and the viewport to window mapping.  Furthermore,
+    clip testing is not performed.
+
+    This greatly simplifies the process of setting the current raster
+    position to a specific window coordinate prior to calling DrawPixels,
+    CopyPixels or Bitmap.
+

+Additions to Chapter 2 of the OpenGL 1.2 Specification (OpenGL Operation)
+
+  - (2.12, p. 41) Insert after third paragraph:
+
+      Alternately, the current raster position may be set by one of the
+      WindowPosMESA commands:
+
+         void WindowPos{234}{sidf}MESA( T coords );
+         void WindowPos{234}{sidf}vMESA( T coords );
+
+      WindosPos4MESA takes four values indicating x, y, z, and w.
+      WindowPos3MESA (or WindowPos2MESA) is analaguos, but sets only
+      x, y, and z with w implicitly set to 1 (or only x and y with z
+      implicititly set to 0 and w implicitly set to 1).
+
+      WindowPosMESA operates like RasterPos except that the current modelview
+      matrix, projection matrix and viewport parameters are ignored and the
+      clip test operation always passes.  The current raster position values
+      are directly set to the parameters passed to WindowPosMESA.  The current
+      color, color index and texture coordinate update the current raster
+      position's associated data.
+
+Additions to the AGL/GLX/WGL Specifications
+
+    None
+
+GLX Protocol
+
+    Not specified at this time.  However, a protocol message very similar
+    to that of RasterPos is expected.
+
+Errors
+
+    INVALID_OPERATION is generated if WindowPosMESA is called betweeen
+    Begin and End.

+    OpenGL 1.0 or later is required
+    This extensions is written against the OpenGL 1.4 Specification.
+    NV_texture_rectangle effects the definition of this extension.
+
+Overview
+
+    This extension supports texture images stored in the YCbCr format.
+    There is no support for converting YCbCr images to RGB or vice versa
+    during pixel transfer.  The texture's YCbCr colors are converted to
+    RGB during texture sampling, after-which, all the usual per-fragment
+    operations take place.  Only 2D texture images are supported (not
+    glDrawPixels, glReadPixels, etc).
+
+    A YCbCr pixel (texel) is a 16-bit unsigned short with two components.
+    The first component is luminance (Y).  For pixels in even-numbered
+    image columns, the second component is Cb.  For pixels in odd-numbered
+    image columns, the second component is Cr.  If one were to convert the
+    data to RGB one would need to examine two pixels from columns N and N+1
+    (where N is even) to deduce the RGB color.

+    In section 3.8.1, Texture Image Specification, on page 125, add
+    another item to the list of TexImage2D and TexImage3D equivalence
+    exceptions:
+
+    * The value of internalformat and format may be YCBCR_MESA to

+      All pixel transfer operations are bypassed.  The texture is stored as
+      YCbCr, not RGB.  Queries of the texture's red, green and blue component

+<h1>1. Introduction</h1>
+<p>The Mini GLX interface facilitates OpenGL rendering on embedded
+devices. The interface is a subset of the GLX interface, plus a minimal
+set of Xlib-like functions.</p>
+<p>Programs written to the Mini GLX specification should run unchanged
+on systems with the X Window System and the GLX extension. The intention
+is to allow flexibility for prototyping and testing.</p>
+<p>This document serves as both the reference guide and programming
+guide for Mini GLX.<br>
+<br>
+</p>
+<h1>2. Mini GLX Concepts</h1>
+<p>The OpenGL specification does not describe how OpenGL rendering
+contexts and drawing surfaces (i.e. the frame buffer) are created and
+managed. Rather, this is handled by an OpenGL window system interface,
+such as Mini GLX.</p>
+<p>There are three main datatypes or resources managed by Mini GLX. The
+resources and their corresponding GLX or Xlib data types are:</p>
+<table cellspacing="10" align="center">
+  <tbody>
+    <tr>
+      <td><u>Resource</u></td>
+      <td><u>Data type</u></td>
+    </tr>
+    <tr>
+      <td>pixel formats</td>
+      <td>X Visual and XVisualInfo</td>
+    </tr>
+    <tr>
+      <td>drawing surfaces</td>
+      <td>X Window or GLXDrawable</td>
+    </tr>
+    <tr>
+      <td>rendering contexts</td>
+      <td>GLXContext</td>
+    </tr>
+  </tbody>
+</table>
+<p>Pixel formats or X Visuals describe the per-pixel attributes of the
+frame buffer.  For example, bits per color component, Z buffer size,
+stencil size, TrueColor vs PseudoColor, etc.</p>
+<p>Drawing surfaces or X Windows typically describe a spatial
+allocation of the frame buffer (i.e. the position and size of a
+rectangular region of pixels).  Since MiniGLX doesn't really support a
+window system, the window is effectively the entire frame buffer.</p>
+<p>A rendering context represents the current OpenGL state such as
+current drawing color, line width, blending mode, texture parameters,
+etc. Several rendering contexts can be created but only one can be in
+use at any given time.</p>
+<p>The Mini GLX interface provides all the functions needed for
+choosing pixel formats, create drawing surfaces, creating rendering
+contexts and binding rendering contexts to drawing surfaces.<br>
+<br>
+</p>
+<h1>3. Using Mini GLX</h1>
+<p>To use the Mini GLX interface in your application, include the
+GL/miniglx.h header file at compile time:</p>
+<blockquote><code>	#include &lt;GL/miniglx.h&gt;<br>
+  </code></blockquote>
+<code></code>Applications should link with libGL.so (i.e. <code>gcc
+myprogram.o -lGL -o myprogram</code>). &nbsp;libGL.so implements the
+MiniGLX API functions and, in turn, loads a hardware-specific device
+driver (such as <code>radeon_dri.so</code>) at runtime. &nbsp;The
+environment variable <code>LIBGL_DRIVERS_PATH</code> should name the
+directory where these modules are located.<br>
+<br>
+Prior to running a MiniGXL application, the following kernel modules
+must be installed:<br>
+<br>
+<div style="margin-left: 40px;"> agpgart.o<br>
+radeonfb.o &nbsp;(assuming Radeon hardware)<br>
+radeon.o &nbsp;(assuming Radeon hardware)<br>
+</div>
+<code></code> <br>
+Finally, MiniGLX reads a configuration file (by default,<code>
+/etc/miniglx.conf</code>) to determine basic configuration information.
+&nbsp;The configuration file may also be located in the directory
+specified by the <code>MINIGLX_CONF</code> environment variable).<br>
+<br>
+The remainder of this section describes the MiniGLX API functions.<br>
+<br>
+<h2>3.1 Initialization</h2>
+<p>The XOpenDisplay function is used to initialize the graphics system:</p>
+<blockquote>
+  <pre>Display *XOpenDisplay(const char *displayname)<br></pre>
+</blockquote>
+<p>The <code>displayName</code> parameter is currently ignored in Mini
+GLX. It is recommended that <code>NULL</code> be passed as the<code>displayName</code>
+parameter.</p>
+<p>If XOpenDisplay is able to initialize the graphics system a pointer
+to a Display will be returned.  Otherwise, NULL will be returned.</p>
+<h2>3.2 Choosing a Visual</h2>
+<p>A visual (i.e. pixel format) must be chosen before a drawing surface
+or rendering context can be created.  This is done with the
+glXChooseVisual function:</p>
+<blockquote>
+  <pre>XVisualInfo *glXChooseVisual(Display *dpy, int screen, const int *attribList)<br></pre>
+</blockquote>
+<p><code>dpy</code> is a pointer to the display returned by
+XOpenDisplay. </p>
+<p><code>screen</code> is currently ignored by Mini GLX and should be
+zero. </p>
+<p><code>attribList</code> is a list of GLX attributes which describe
+the desired pixel format.  It is terminated by the token <code>None</code>.
+The attributes are as follows:</p>
+<blockquote>
+  <dl>
+    <dt><code>GLX_USE_GL</code></dt>
+    <dd>This attribute should always be present in order to maintain
+compatibility with GLX.</dd>
+    <dt><code>GLX_RGBA</code></dt>
+    <dd>If present, only RGBA pixel formats will be considered.
+Otherwise, only color index formats are considered.</dd>
+    <dt><code>GLX_DOUBLEBUFFER</code></dt>
+    <dd>if present, only double-buffered pixel formats will	be chosen.</dd>
+    <dt><code>GLX_RED_SIZE n</code></dt>
+    <dd>Must be followed by a non-negative integer indicating the
+minimum number of bits per red pixel component that is acceptable.</dd>
+    <dt><code>GLX_GREEN_SIZE n</code></dt>
+    <dd>Must be followed by a non-negative integer indicating the
+minimum number of bits per green pixel component that is acceptable.</dd>
+    <dt><code>GLX_BLUE_SIZE n</code></dt>
+    <dd>Must be followed by a non-negative integer indicating the
+minimum number of bits per blue pixel component that is acceptable.</dd>
+    <dt><code>GLX_ALPHA_SIZE n</code></dt>
+    <dd>Must be followed by a non-negative integer indicating the
+minimum number of bits per alpha pixel component that is acceptable.</dd>
+    <dt><code>GLX_STENCIL_SIZE n</code></dt>
+    <dd>Must be followed by a non-negative integer indicating the
+minimum number of bits per stencil value that is acceptable.</dd>
+    <dt><code>None</code></dt>
+    <dd>This token is used to terminate the attribute list.</dd>
+  </dl>
+</blockquote>
+<p>glXChooseVisual will return a pointer to an XVisualInfo object which
+most closely matches the requirements of the attribute list.  If there
+is no visual which matches the request, NULL will be returned.</p>
+<p>Note that visuals with accumulation buffers and depth buffers are
+not available.<br>
+<br>
+</p>
+<h2>3.3 Creating a Drawing Surface</h2>
+<p>Drawing surfaces are created as X windows. &nbsp;For Mini GLX,
+windows are <i>full-screen</i>; they cover the entire frame buffer.
+&nbsp;Also, Mini GLX imposes a limit of one window.  A second window
+cannot be created until the first one is destroyed.</p>
+<h3>3.3.1 Window Creation</h3>
+<p>The XCreateWindow function is used to create a drawing surface:</p>
+<blockquote>
+  <pre>Window XCreateWindow( Display *display,<br>                      Window parent,<br>                      int x, int y,<br>                      unsigned int width, unsigned int height,<br>                      unsigned int borderWidth,<br>                      int depth,<br>                      unsigned int class,<br>                      Visual *visual,<br>                      unsigned long valuemask,<br>                      XSetWindowAttributes *attributes )<br></pre>
+</blockquote>
+<p>The parameters are as follows:</p>
+<blockquote>
+  <dl>
+    <dt><code>display</code></dt>
+    <dd>A Display pointer, as returned by XOpenDisplay.</dd>
+    <dt><code>parent</code></dt>
+    <dd>The parent window for the new window.  For Mini GLX, this
+should be<code>RootWindow(dpy, 0)</code>.</dd>
+    <dt><code>x, y</code></dt>
+    <dd>The position of the window.  For Mini GLX, both values should
+be zero.</dd>
+    <dt><code>width, height</code></dt>
+    <dd>The size of the window.  For Mini GLX, this specifies the
+desired screen size such as 1024, 768 or 1280, 1024.</dd>
+    <dt><code>borderWidth</code></dt>
+    <dd>This parameter should be zero.</dd>
+    <dt><code>depth</code></dt>
+    <dd>The pixel depth for the window.  For Mini GLX this should be
+the depth found in the XVisualInfo object returned by <code>glxChooseVisual</code>.</dd>
+    <dt><code>class</code></dt>
+    <dd>The window class.  For Mini GLX this value should be <code>InputOutput</code>.</dd>
+    <dt><code>visual</code></dt>
+    <dd>This parameter should be the <code>visual</code> field of the <code>XVisualInfo</code>
+object returned by <code>glxChooseVisual</code>.</dd>
+    <dt><code>valuemask</code></dt>
+    <dd>This parameter indicates which fields of the <code>XSetWindowAttributes</code>
+are to be used. For Mini GLX this is typically the bitmask<code>CWBackPixel
+| CWBorderPixel | CWColormap</code>.</dd>
+    <dt><code>attributes</code></dt>
+    <dd>Initial window attributes. Of the fields in the <code>XSetWindowAttributes</code>
+structure, the<code>background_pixel</code>, <code>border_pixel</code>
+and <code>colormap</code> fields should be set. &nbsp;See the discussion
+below regarding colormaps.</dd>
+  </dl>
+</blockquote>
+<p><code>XCreateWindow</code> will return a window handle if it succeeds
+or zero if it fails.</p>
+<h3>3.3.2 Window Mapping</h3>
+<p>To display the window the XMapWindow function must be called:</p>
+<blockquote>
+  <pre>void XMapWindow(Display *dpy, Window w)</pre>
+</blockquote>
+<p>This function does nothing in Mini GLX but is required for Xlib/GLX
+compatibility</p>
+<h3>3.3.3 Colormaps<br>
+</h3>
+<p>Xlib requires specification of a colormap when creating a window.
+&nbsp;For purposes of interoperability, Mini GLX requires this as well,
+though the colormap is not actually used. &nbsp;The XCreateColormap
+function is used to create a colormap:</p>
+<blockquote><code>Colormap XCreateColormap(Display *dpy, Window window,
+Visual *visual, int alloc)</code><br>
+  <code></code></blockquote>
+<p>The parameters are as follows:<br>
+</p>
+<blockquote>
+  <dl>
+    <dt><code>dpy</code></dt>
+    <dd>The display handle as returned by XOpenDisplay.</dd>
+    <dt><code>window</code></dt>
+    <dd> This parameter is ignored by Mini GLX but should be the value
+returned by the <code>RootWindow(dpy, 0)</code> macro.<br>
+    </dd>
+    <dt><code>visual</code></dt>
+    <dd>This parameter is ignored by Mini GLX but should be the visual
+field of the XVisualInfo object returned by glXChooseVisual. </dd>
+    <dt><code>alloc</code></dt>
+    <dd>This parameter is ignored by Mini GLX but should be set to <code>AllocNone</code>.</dd>
+  </dl>
+</blockquote>
+<br>
+<h2>3.4 Creating a Rendering Context</h2>
+<p>An OpenGL rendering context is created with the <code>glXCreateContext</code>
+function:</p>
+<blockquote>
+  <pre>GLXContext glXCreateContext(Display *dpy, XVisualInfo *visInfo, GLXContext shareList, Bool direct)<br></pre>
+</blockquote>
+<p>The parameters are as follows:</p>
+<blockquote>
+  <dl>
+    <dt><code>dpy</code></dt>
+    <dd>The display handle as returned by XOpenDisplay.</dd>
+    <dt><code>visInfo</code></dt>
+    <dd>The visual as returned by glXChooseVisual.</dd>
+    <dt><code>shareList</code></dt>
+    <dd>If non-zero, texture objects and display lists are shared with
+the named rendering context. If zero, texture objects and display lists
+will (initially) be private to this context. They may be shared when a
+subsequent context is created.</dd>
+    <dt><code>direct</code></dt>
+    <dd>Specifies whether direct or indirect rendering is desired. For
+Mini GLX this value is ignored but it should be set to <code>True</code>.</dd>
+  </dl>
+</blockquote>
+<p><code>glXCreateContext</code> will return a GLXContext handle if it
+succeeds or zero if it fails due to invalid parameter or insufficient
+resources.<br>
+<br>
+</p>
+<h2>3.5 Binding a Rendering Context</h2>
+<p>The final step before beginning OpenGL rendering is to bind (i.e.
+activate) a rendering context and drawing surface with the
+glXMakeCurrent function:</p>
+<blockquote>
+  <pre>Bool glXMakeCurrent(Display *dpy, GLXDrawable drawable, GLXContext ctx)<br></pre>
+</blockquote>
+<p>The parameters are as follows:</p>
+<blockquote>
+  <dl>
+    <dt><code>dpy</code></dt>
+    <dd>The display handle, as returned by XOpenDisplay.</dd>
+    <dt><code>drawable</code></dt>
+    <dd>The window or drawable to bind to the rendering context. This
+should be the value returned by XCreateWindow.</dd>
+    <dt><code>ctx</code></dt>
+    <dd>The rendering context to bind, as returned by glXCreateContext.</dd>
+  </dl>
+</blockquote>
+<p>If glXMakeCurrent succeeds True is returned.  Otherwise False is
+returned to indicate an invalid display, window or context parameter.</p>
+<p>After the rendering context has been bound to the drawing surface
+OpenGL rendering can begin.</p>
+<p>The current rendering context may be unbound by calling
+glXMakeCurrent with the window and context parameters set to zero.</p>
+<p>An application may create any number of rendering contexts and bind
+them as needed. Note that binding a rendering context is generally not a
+light-weight operation. &nbsp;Most simple OpenGL applications create
+only one rendering context.<br>
+<br>
+</p>
+<h2>3.6 Color Buffer Swapping</h2>
+<p>A double buffered window has two color buffers: a front buffer and a
+back buffer.  Normally, rendering is directed to the back buffer while
+the front buffer is displayed.  When rendering of a frame is finished
+the front and back buffers are swapped to provide the illusion of
+instanteous screen updates.</p>
+<p>The color buffers for a particular window (i.e. drawable) may be
+swapped with the glXSwapBuffers command:</p>
+<blockquote>
+  <pre>void glXSwapBuffers(Display *dpy, GLXDrawable drawable)<br></pre>
+</blockquote>
+Any pending rendering commands will be completed before the buffer swap
+takes place.<br>
+<br>
+Calling glXSwapBuffers on a window which is single-buffered has no
+effect.<br>
+<br>
+<h2>3.7 Releasing Resources</h2>
+<h3>3.7.1 Releasing Rendering Contexts</h3>
+<p>A rendering context may be destroyed by calling glXDestroyContext:</p>
+<blockquote>
+  <pre>void glXDestroyContext(Display *dpy, GLXContext ctx)<br></pre>

+<h3>3.7.2 Releasing Windows</h3>
+<p>A window may be destroyed by calling XDestroyWindow:</p>
+<blockquote>
+  <pre>void XDestroyWindow(Display *dpy, Window window)<br></pre>
+</blockquote>
+<h3>3.7.3 Releasing Visuals</h3>
+<p>An XVisualInfo object may be freed by calling XFree:</p>

+<h2>3.8 Query Functions</h2>
+<h3>3.8.1 Querying Available Visuals</h3>
+A list of all available visuals can be obtained with the XGetVisualInfo
+function:<br>
+<br>
+<div style="margin-left: 40px;"><code>XVisualInfo
+*XGetVisualInfo(Display *dpy, long vinfo_mask, XVisualInfo
+*vinfo_template, int *nitems_return)<br>
+</code></div>
+<br>
+The parameters are as follows:<br>
+<blockquote>
+  <dl>
+    <dt><code>dpy</code></dt>
+    <dd>The display handle, as returned by XOpenDisplay.</dd>
+    <dt><code>vinfo_mask</code></dt>
+    <dd>A bitmask indicating which fields of the vinfo_template are to
+be matched. &nbsp;The value must be VisualScreenMask.</dd>
+    <dt><code>vinfo_template</code></dt>
+    <dd>A template whose fields indicate which visual attributes must
+be matched by the results. &nbsp;The screen field of this structure must
+be zero.</dd>
+    <dt><code>nitems_return</code></dt>
+    <dd>Returns the number of visuals returned. </dd>
+  </dl>
+</blockquote>
+The return value is the address of an array of all available visuals.<br>
+<br>
+An example of using XGetVisualInfo to get all available visuals follows:<br>
+<br>
+<div style="margin-left: 40px;"><code>XVisualInfo visTemplate, *results;</code><br>
+<code>int numVisuals;</code><br>
+<code>Display *dpy = XOpenDisplay(NULL);</code><br>
+<code>visTemplate.screen = 0;</code><br>
+<code>results = XGetVisualInfo(dpy, VisualScreenMask, &amp;visTemplate,
+&amp;numVisuals);</code><br>
+<code></code></div>
+<br>
+<h3>3.8.2 Querying Visual Attributes</h3>
+<p>The GLX attributes of an X visual may be queried with the
+glXGetConfig function:</p>
+<blockquote>
+  <pre>int glXGetConfig(Display *dpy, XVisualInfo *vis, int attribute, int *value)<br></pre>
+</blockquote>
+<p>The parameters are as follows:</p>
+<blockquote>
+  <dl>
+    <dt><code>dpy</code></dt>
+    <dd>The display handle, as returned by XOpenDisplay.</dd>
+    <dt><code>vis</code></dt>
+    <dd>The visual, as returned by glXChooseVisual.</dd>
+    <dt><code>attribute</code></dt>
+    <dd>The attribute to query.  The attributes are listed below.</dd>
+    <dt><code>value</code></dt>
+    <dd>Pointer to an integer in which the result of the query will be
+stored. </dd>
+  </dl>
+</blockquote>
+<p>The return value will be zero if no error occurs.<code>
+&nbsp;GLX_INVALID_ATTRIBUTE</code> will be returned if the attribute
+parameter is invalid.<code> &nbsp;GLX_BAD_VISUAL</code> will be returned
+if the XVisualInfo parameter is invalid.</p>
+<p>The following attributes may be queried:</p>
+<blockquote>
+  <dl>
+    <dt><code>GLX_USE_GL</code></dt>
+    <dd>The result will be <code>True</code> or <code>False</code> to
+indicate if OpenGL rendering is supported with the visual.  Mini GLX
+always return <code>True</code>.</dd>
+    <dt><code>GLX_RGBA</code></dt>
+    <dd>The result will be <code>True</code> for RGBA visuals or <code>False</code>
+for color index visuals.</dd>
+    <dt><code>GLX_DOUBLEBUFFER</code></dt>
+    <dd>The result will be <code>True</code> if the visual has two
+color buffers or <code>False</code> if the visual has one color buffer.</dd>
+    <dt><code>GLX_RED_SIZE</code></dt>
+    <dd>The result will be the number of red bits per pixel.</dd>
+    <dt><code>GLX_GREEN_SIZE</code></dt>
+    <dd>The result will be the number of green bits per pixel.</dd>
+    <dt><code>GLX_BLUE_SIZE</code></dt>
+    <dd>The result will be the number of blue bits per pixel.</dd>
+    <dt><code>GLX_ALPHA_SIZE</code></dt>
+    <dd>The result will be the number of alpha bits per pixel.</dd>
+    <dt><code>GLX_DEPTH_SIZE</code></dt>
+    <dd>The result will be the number of bits per Z value.</dd>
+    <dt><code>GLX_STENCIL_SIZE</code></dt>
+    <dd>The result will be the number of bits per stencil value.<br>
+      <br>
+    </dd>
+  </dl>
+</blockquote>
+<h3>3.8.3 Querying the Current Rendering Context</h3>
+<p>The current rendering context can be queried with
+glXGetCurrentContext: </p>
+<blockquote>
+  <pre>GLXContext glXGetCurrentContext(void)<br></pre>
+</blockquote>
+<p>Zero will be returned if no context is currently bound.<br>
+<br>
+</p>
+<h3>3.8.4 Querying the Current Drawable</h3>
+<p>The current drawable (i.e. window or drawing surface) can be queried
+with glXGetCurrentDrawable:</p>
+<blockquote>
+  <pre>GLXDrawable glXGetCurrentDrawable(void)<br></pre>
+</blockquote>
+<p>Zero will be returned if no drawable is currently bound.<br>
+<br>
+</p>
+<h3>3.8.5 Function Address Queries</h3>
+<p>The glXGetProcAddress function will return the address of any
+available OpenGL or Mini GLX function:</p>
+<blockquote>
+  <pre>void *glXGetProcAddress(const GLubyte *procName)<br></pre>
+</blockquote>
+<p>If <code>procName</code> is a valid function name, a pointer to that
+function will be returned. &nbsp;Otherwise, NULL will be returned.</p>
+<p>The purpose of glXGetProcAddress is to facilitate using future
+extensions to OpenGL or Mini GLX.  If a future version of the library
+adds new extension functions they'll be accessible via
+glXGetProcAddress. The alternative is to hard-code calls to the new
+functions in the application but doing so will prevent linking the
+application with older versions of the library.<br>
+<br>
+</p>
+<h2>3.9 Versioning</h2>
+The Mini GLX version can be queried at run time with glXQueryVersion:
+<blockquote>
+  <pre>Bool glXQueryVersion(Display *dpy, int *major, int *minor)<br></pre>
+</blockquote>
+<p><code>major</code> will be set to the major version number and<code>minor</code>
+will be set to the minor version number.<code>True</code> will be
+returned if the function succeeds. <code>False</code> will be returned
+if the function fails due to invalid parameters. The <code>dpy</code>
+argument is currently ignored, but should be the value returned by
+XOpenDisplay.</p>
+<p>At compile time, the Mini GLX interface version can be tested with
+the MINI_GLX_VERSION_1_<i>x</i> preprocessor tokens. For example, if
+version 1.0 of Mini GLX is supported, then<code> MINI_GLX_VERSION_1_0</code>
+will be defined. If version 1.1 of Mini GLX is supported, then<code>
+MINI_GLX_VERSION_1_1</code> will be defined.</p>
+<p>At the time of writing the current Mini GLX version is 1.0.<br>
+<br>
+</p>
+<h1>4.0 Interoperability with GLX and Xlib</h1>
+While Mini GLX strives to be compatible with GLX and Xlib there are
+some unavoidable differences which must be taken into consideration.<br>
+<h2>4.1 Public vs Private Structures</h2>
+The structure of many X data types is public. &nbsp;For example, the <code>Display</code>
+data type is defined as a structure in /usr/include/X11/Xlib.h and
+programmers may access any fields of that structure at will. &nbsp;Mini
+GLX also defines a Display data type but its fields are hidden and not
+visiblein <code>miniglx.h</code>. &nbsp;Duplicating the Xlib
+declaration for the <code>Display</code> data type in minigl.h would
+require defining a large number of other superfluous Xlib datatypes.<br>
+<br>
+Mini GLX users are discouraged from directly accessing the fields of
+Xlib data types to maximize portability - though this is unavoidable to
+some extent. &nbsp;For example, the <code>XVisualInfo</code> and <code>XSetWindowAtttributes</code>
+data types must be completely public.
+<h2>4.2 Macros</h2>
+In some cases, Xlib defines macros which are meant to be used instead
+of direct structure accesses. &nbsp;For example, the <code>RootWindow(dpy,
+screen)</code> macro returns the root window for a given screen on a
+given display. &nbsp;Unfortunately, macros do nothing to aid in ABI
+compatibility since they are resolved at compile time instead of at
+link/run time.<br>
+<br>
+Mini GLX also defines a <code>RootWindow</code> macro since it's
+essential for creating windows. &nbsp;But the implementation of this
+macro by Xlib and Mini GLX is completely different.<br>
+<h2>4.3 Summary</h2>
+Because Xlib and Mini GLX define data types and macros differently,
+Mini GLX applications must be recompiled when retargeting Mini GLX or
+native Xlib/GLX. &nbsp;That is, applications can't simply be re-linked
+because of ABI incompatibilities.<br>
+<br>
+Nevertheless, the fact that Mini GLX programs can be recompiled for
+Xlib and GLX increases portability and flexibility for testing and
+prototyping.<br>
+<br>
+<h1>5.0 Example Program</h1>
+<p>This section shows an example program which uses the Mini GLX
+interface. The program simply draws several frames of a rotating square.<br>
+</p>
+<p>The program may be compiled for use with Xlib/GLX or Mini GLX by
+setting the <code>USE_MINIGLX</code> token to 0 or 1, respectively.
+&nbsp;Note that the only difference is the header files which are
+included.<br>

+
+A Voodoo-based videocard/accelerator
+DOS (with DJGPP), Windows9x/2k (with MinGW), Linux
+Glide3x library for your OS
+
+http://sourceforge.net/projects/glide/
+
+
+
+How to compile:
+---------------
+
+DJGPP:
+   Place the Glide3 SDK in the top Mesa directory:
+	$(MESA)/glide3/include/
+		3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+	$(MESA)/glide3/lib/
+		libgld3x.a, libgld3i.a, glide3x.dxe
+   Type:
+	make -f Makefile.DJ X86=1 FX=1
+   Look into the makefile for further information.
+
+MinGW:
+   Place the Glide3 SDK in the top Mesa directory:
+	$(MESA)/glide3/include/
+		3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+	$(MESA)/glide3/lib/
+		libglide3x.a, glide3x.dll
+   Type:
+	make -f Makefile.mgw X86=1 FX=1
+   Look into the makefile for further information.
+
+Linux:
+   Place the Glide3 SDK in /usr/local/glide
+	/usr/local/glide/include/
+		3dfx.h, g3ext.h, glide.h, glidesys.h, glideutl.h, sst1vid.h
+	/usr/local/glide/lib/
+		libglide3x.a, libglide3x.so
+   Type:
+	make linux-glide
+	or
+	make linux-x86-glide
+
+
+
+Compilation defines:
+--------------------
+
+FX_DEBUG
+	enable driver debug code
+FX_TRAP_GLIDE
+	enable Glide trace code
+FX_PACKEDCOLOR
+	use packed color in vertex structure
+FX_TC_NAPALM
+	map GL_COMPRESSED_RGB[A] to FXT1. Works with VSA100-based cards only.
+FX_COMPRESS_S3TC_AS_FXT1_HACK
+	map S3TC to FXT1
+FX_RESCALE_BIG_TEXURES_HACK
+	fake textures larger than HW can support
+	(see MESA_FX_MAXLOD environment variable)
+
+
+
+Environment variables:
+----------------------
+
+The following environment variables affect MesaFX. Those that affect Glide
+only, are beyond the scope of this section. Entries that don't have a "Value"
+field, can have any value whatsoever
+	ex: set MESA_FX_IGNORE_CMBEXT=y
+
+"Note" (*) means that the environment variable affects Glide, too; also, if
+the var is not found in the environment, it is searched in windoze registry.
+"Note" (!) means that the environment variable is not working as expected;
+may have undefined effects, might have effects only at Glide level or might
+not have any effect whatsoever. Caveat emptor! Those are to be revised soon.
+
+It is recommended to leave the envvars alone, so that Mesa/Glide will run with
+default values. Use them only when you experience crashes or strange behavior.

+Info for Mesa 4.1
+-----------------
+
+The 3dfx Glide driver in Mesa is disabled by default.  Not too many people
+use this driver anymore and at some point down the road it will be dropped.
+
+To use/enable the Glide driver either do this:
+
+'./configure --with-glide=DIR'    Where DIR is the location of Glide, like
+                                  /usr/ or /usr/local
+
+OR
+
+'make linux-x86-glide'     If using the old-style Makefile system.
+
+The rest of this file hasn't changed since Mesa 3.3.  Some of it's out of
+date, but some is still valid.
+
+
+
+What do you need ?
+------------------
+
+	- A PC with a 3Dfx Voodoo1/2 Graphics or Voodoo Rush based board
+	  (Pure3D, Monster 3D, R3D, Obsidian, Stingray 128/3D, etc.).
+	  The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
+	  under Linux (more information in the "Useful Glide Environment
+	  Variables");
+
+	- The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine).
+	  The Voodoo2 requires the Glide library 2.51. The Glide 3.1 is not
+	  compatible with the Glide 2.x so it doesn't work with the current
+	  version of the driver;
+
+	- A compiler supported by the Glide library (Micro$oft VC++ (tested),
+	  Watcom (tested), GCC for Linux (tested), etc.);
+
+	- It's nice to have two monitors - one for your normal graphics
+	  card and one for your 3Dfx card. If something goes wrong with
+	  an application using the 3Dfx hardware you can still see your
+	  normal screen in order to recover.
+
+
+
+Tested on:
+----------
+	Windows 95 - David Bucciarelli
+	Windows NT - Henri Fousse
+	MS-DOS
+	Linux - Daryll Strauss, Brian Paul, David Bucciarelli
+	FreeBSD
+	BeOS - Duncan Wilcox
+	MacOS - Fazekas Miklos
+
+
+What is able to do ?
+--------------------
+
+	- It is able accelerate points, lines and polygon with flat
+	  shading, gouraud shading, Z-buffer, texture mapping, blending, fog and
+	  antialiasing (when possible). There is also the support for rendering
+	  in a window with a slow trick for the Voodoo Graphics (available only
+	  for Linux) and at full speed with the Voodoo Rush chipset.
+	  Under Linux is also possible to switch on-the-fly between the fullscreen
+	  and in-window rendering hack.
+	  There is also the support for using more than one Voodoo Graphics in the
+	  some application/PC (you can create one context for each board and use
+	  multiple video outputs for driving monitors, videoprojectors or HMDs).
+	  The driver is able to fallback to pure software rendering when afeature
+	  isn't supported by the Voodoo hardware (however software rendering is
+	  very slow compared to hardware supported rendering)
+
+
+
+How to compile:
+---------------
+
+Linux:
+------
+	Here are the basic steps for using the 3Dfx hardware with Mesa
+	on Linux:
+
+	- You'll need the Glide library and headers.  Mesa expects:
+		/usr/local/glide/include/*.h        // all the Glide headers
+		/usr/local/glide/lib/libglide2x.so
+
+	  If your Glide libraries and headers are in a different directory
+	  you'll have to modify the Mesa-config and mklib.glide files.
+
+	- Unpack the MesaLib-3.1.tar.gz and MesaDemos-3.1.tar.gz archives;
+
+	- If you're going to use a newer Mesa/Glide driver than v0.27 then
+          unpack the new driver archive over the Mesa directory.
+
+	- In the Mesa-3.1 directory type "make linux-glide"
+
+	- Compilation _should_ finish without errors;
+
+	- Set your LD_LIBRARY_PATH environment variable so that the
+	  libglide2x.so and Mesa library files can be found.  For example:
+	    setenv LD_LIBRARY_PATH "/usr/local/glide/lib:/SOMEDIR/Mesa-3.1/lib"
+
+	- You'll have to run Glide-based programs as root or set the suid
+	  bit on executables;
+
+	- Try a demo:
+	    cd gdemos
+	    su
+	    setenv MESA_GLX_FX f
+	    ./gears     (hit ESC to exit)
+
+	- You can find the demos especially designed for the Voodoo driver in
+	  in the Mesa-3.1/3Dfx/demos directory (type "make" in order to compile
+	  everything).
+
+MacOS:
+------
+	Check the WEB page at http://valerie.inf.elte.hu/~boga/Mesa.html
+      
+MS Windows:
+-----------
+
+	For the MSVC++:
+	- The glide2x.lib have to be in the default MSVC++ lib directory;
+
+	- The Glide headers have to be in the default MSVC++ include directory;
+
+	- You must have the vcvars32.bat script in your PATH;
+
+	- Go to the directory Mesa-3.1 and run the mesafx.bat;
+
+	- The script will compile everything (Mesa-3.1/lib/OpenGL32.{lib,dll},
+	  Mesa-3.1/lib/GLU32.{lib,dll}, Mesa-3.1/lib/GLUT32.{lib,dll} and
+          Voodoo demos);
+
+	- At the end, you will be in the Mesa-3.1/3Dfx/demos directory;
+
+	- Try some demo (fire.exe, teapot.exe, etc.) in order to check if
+	  everything is OK (you can use Alt-Tab or Ctrl-F9 to switch between
+	  the Voodoo screen and the windows desktop);
+
+	- Remember to copy the Mesa OpenGL32.dll, GLU32.dll and GLUT32.dll in the
+          some directory were you run your Mesa based applications.
+
+	- I think that you can easy change the Makefile.fx files in order
+	  to work with other kind of compilers;
+
+	- To discover how open the 3Dfx screen, read the sources under
+	  the Mesa-3.1/3Dfx/demos directory. You can use the GLUT library or
+          the Diego Picciani's wgl emulator.
+
+	NOTE: the MSVC++ 5.0 optimizer is really buggy. Also if you install the
+	SP3, you could have some problem (you can disable optimization in order
+	solve these kind of problems).
+
+
+Doing more with Mesa & Linux Glide:
+-----------------------------------
+
+	The MESA_GLX_FX environment variable can be used to coax most
+	GLX-based programs into using Glide (and the __GLUT library
+	is GLX-based__).
+
+        Full-screen 3Dfx rendering:
+        ---------------------------
+
+	1. Set the MESA_GLX_FX variable to "fullscreen":
+
+		ksh:
+			export MESA_GLX_FX = "fullscreen"
+		csh:
+			setenv MESA_GLX_FX fullscreen
+
+	2. As root, run a GLX-based program (any GLUT demo on Linux).
+	
+	3. Be careful:  once the 3Dfx screen appears you won't be able
+	to see the GLUT windows on your X display.  This can make using
+	the mouse tricky!  One solution is to hook up your 3Dfx card to
+	a second monitor.  If you can do this then set these env vars
+	first:
+
+		setenv SST_VGA_PASS 1
+		setenv SST_NOSHUTDOWN
+	
+	or for the Voodoo2:
+
+		setenv SSTV2_VGA_PASS 1
+		setenv SSTV2_NOSHUTDOWN
+
+        Rendering into an X window with the help of the Voodoo hardware:
+        ----------------------------------------------------------------
+
+	1. Start your X server in 16 bpp mode (XFree86:  startx -- -bpp 16)
+	   in order to have the best performance and the best visual
+	   quality. However you can use any visual depth supported by X.
+
+	2. Set the following environment variables:
+		export MESA_GLX_FX="window"	# to enable window rendering
+		export SST_VGA_PASS=1	# to stop video signal switching
+		export SST_NOSHUTDOWN=1	# to stop video signal switching
+	    OR
+		setenv MESA_GLX_FX window
+		setenv SST_VGA_PASS 1
+		setenv SST_NOSHUTDOWN 1
+
+	(the Voodoo2 requires to use "SSTV2_" instead "SST_").
+
+	3. As root, try running a GLX-based program
+
+	How does it work?  We use the 3Dfx hardware to do rendering then
+	copy the image from the 3Dfx frame buffer into an X window when
+	the SwapBuffers() function is called.  The problem with this
+	idea is it's slow.  The image must be copied from the 3Dfx frame
+	buffer to main memory then copied into the X window (and when the X
+	visual depth doesn't match the Voodoo framebufffer bit per pixel, it
+	is required also a pixel format translation).
+
+	NOTE: the in-window rendering feature only works with double-buffering.
+
+
+        On the fly switching between in window rendering and full screen rendering
+	--------------------------------------------------------------------------
+
+	The Mesa 2.6 has introduced the capability of switching
+	on-the-fly between the fullscreen/fullspeed rendering and the in-window
+	hack and vice versa. The on-the-fly switching requires a direct support
+	by the application but it is really easy to add. You have to start
+	your X server in 16 bpp mode and to add the following lines to your
+	application:
+
+		#if defined(FX) && define(XMESA)
+		#include <GL/xmesa.h>
+
+		static int fullscreen=1;
+		#endif
+
+		...
+
+		/* In the GLUT keyboard event callback */
+
+		#if defined(FX) && !define(WIN32)
+		  case ' ':
+		    fullscreen=(!fullscreen);
+		    XMesaSetFXmode(fullscreen ? XMESA_FX_FULLSCREEN : XMESA_FX_WINDOW);
+		    break;
+		#endif
+		...
+
+       	See the 3Dfx/demos/tunnel.c program
+       	for an example.  You have to set the -DXMESA flag in the Makefile's COPTS
+       	to enable it.
+
+  	Rendering into an X window with the X11 software driver:
+        --------------------------------------------------------
+
+	Set the MESA_GLX_FX variable to "disable" your GLX-based program will use
+	the X11 software driver (the 3Dfx hardware isn't used at all).
+
+
+
+Useful Glide Environment Variables:
+-----------------------------------
+
+	- To disable the 3Dfx logo, set the FX_GLIDE_NO_SPLASH variable.
+
+	- To disable video signal switching:
+		setenv SST_VGA_PASS 1
+		setenv SST_NOSHUTDOWN
+	  or for the Voodoo2:
+		setenv SSTV2_VGA_PASS 1
+		setenv SSTV2_NOSHUTDOWN
+
+        - To set the default screen refresh rate:
+                setenv SST_SCREENREFRESH=75
+
+          the supported values are 60, 70, 72, 75, 80, 85, 90, 100, 120.
+
+	- To force the Mesa library to swap buffers as fast as possible,
+	  without any vertical blanking synchronization (useful for benchmarks):
+		setenv FX_GLIDE_SWAPINTERVAL 0
+                setenv SST_SWAP_EN_WAIT_ON_VIDSYNC 0
+
+	- You can slight improve the performances of your Voodoo1 board with
+	  the following env. var.:
+		setenv SST_FASTMEM 1
+		setenv SST_PCIRD 1
+		setenv SST_GRXCLK 57
+
+	  (don't use this setting with the Quantum3D 100SB or with any other
+	  SLI configuration: it will hang everything !).
+	  The following setting can be used with the Voodoo2:
+		setenv SSTV2_FASTMEM_RAS_READS=1
+		setenv SSTV2_FASTPCIRD=1
+		setenv SSTV2_GRXCLK=95
+
+	- The Quantum3D Obsidian3D-2 X-24 requires some special env. setting
+	  in order to work under Linux:
+
+		export SSTV2_FT_CLKDEL=5
+		export SSTV2_TF0_CLKDEL=7
+		export SSTV2_TF1_CLKDEL=7
+		export SSTV2_TF2_CLKDEL=7
+		export SSTV2_SLIM_VIN_CLKDEL=3
+		export SSTV2_SLIM_VOUT_CLKDEL=2
+		export SSTV2_SLIS_VIN_CLKDEL=3
+		export SSTV2_SLIS_VOUT_CLKDEL=2
+
+	  (Thanks to Phil Ross for this trick).
+
+
+
+
+The Mesa/Voodoo Environment Variables:
+--------------------------------------
+
+	- Only for Windows/Voodoo Rush users, if you define the
+	  env. var. MESA_WGL_FX:
+		export MESA_WGL_FX=fullscreen
+	  you will get fullscreen rendering;
+
+	- Only for Windows/Voodoo Rush users, if you define the
+	  env. var. MESA_WGL_FX:
+		export MESA_WGL_FX=window
+	  you will get window rendering (default value);
+
+	- Only for Linux users, you can find more informations about
+	  the env. var. MESA_GLX_FX in the "Doing more with Mesa & Linux Glide"
+	  section;
+
+	- If you define the env. var. MESA_FX_SWAP_PENDING:
+		export MESA_FX_SWAP_PENDING=4
+	  you will able to set the maximum number of swapbuffers
+	  commands in the Voodoo FIFO after a swapbuffer (default value: 2);
+
+        - If you define the env. var. MESA_FX_INFO:
+		export MESA_FX_INFO=1
+          you will get some useful statistic.
+
+        - If you define the env. var. MESA_FX_NO_SIGNALS:
+		export MESA_FX_NO_SIGNALS=1
+          Mesa/FX will not install atexit() or signal() handlers.
+
+
+
+Know BUGS and Problems:
+-----------------------
+
+	- fog doesn't work in the right way when using the glDepthRange() function;
+
+	- Maximum texture size: 256x256 (this is an hardware limit);
+
+	- Texture border aren't yet supported;
+
+	- A GL_BLEND in a glTexEnv() is not supported (it is an hardware limit);
+
+        - Use the glBindTexture extension (standard in OpenGL 1.1) for texture
+	  mapping (the old way: glTexImage inside a display list, download
+	  the texture map each time that you call the display list !!!);
+
+	- Stencil buffer and Accumulation buffer are emulated in software (they are not
+	  directly supported by the Hardware);
+
+	- Color index mode not implemented (this is an hardware limit);
+
+	- Thre is an know bug in the Linux Glide library so the in-window-rendering hack
+	  and any other operations that requires to read the Voodoo frame buffer
+	  (like the accumulation buffer support) doesn't work on Voodoo SLI cards.
+
+	- The driver switch to pure software (_slow_) rendering when:
+
+		- Stencil enabled;
+		- Using the Accumulation buffer;
+		- Blend enabled and blend equation != GL_FUNC_ADD_EXT;
+		- Color logic operation enabled and color logic operation != GL_COPY;
+		- Using GL_SEPARATE_SPECULAR_COLOR;
+		- The four values of glColorMask() aren't the some;
+		- Texture 1D or 3D enabled;
+		- Texture function is GL_BLEND;
+		- Using the Multitexture extension with Voodoo cards with only one TMU;
+		- Using the Multitexture extension with Voodoo cards with more than
+		   one TMU, and texture function isn't GL_MODULATE;
+		- Point size is != 1.0 or point params vector != (1.0,0.0,0.0);
+		- Line width != 1.0 or using stipple lines.
+		- Using polygon offset or stipple polygons;
+
+	NOTE: this is list is not yet complete.
+		
+
+Hints and Special Features:
+---------------------------
+
+	- Under Linux and with a Voodoo Graphics board, you can use
+	  XMesaSetFXmode(XMESA_FX_FULLSCREEN or XMESA_FX_WINDOW) in order to
+	  switch on the fly between fullscreen rendering and the in-window-rendering
+	  hack.
+
+	- The driver is able to use all the texture memory available: 2/4MB on
+	  Voodoo1 boards and 8MB (!) on high-end Voodoo1 and Voodoo2 boards.
+
+	- Trilinear filtering is fully supported on Voodoo boards with two TMUs
+	  (high-end Voodoo1 boards and Voodoo2 boards). When only one TMU is
+	  available the driver fallback to bilinear filter also if you ask
+	  for trilinear filtering.
+
+        - The Voodoo driver support multiple Voodoo Graphics boards in the
+          some PC. Using this feature, you can write applications that use
+          multiple monitors, videoprojectors or HMDs for the output. See
+	  Mesa-3.1/3Dfx/demos/tunnel2.c for an example of how setup one
+          context for each board.
+
+	- The v0.19 introduces a new powerful texture memory manager: the
+	  texture memory is used as a cache of the set of all defined texture
+	  maps. You can now define several MBs of texture maps also with a 2MB
+	  of texture memory (the texture memory manager will do automatically
+	  all the swap out/swap in
+	  texture memory work). The new texture memory manager has also
+	  solved a lot of other bugs/no specs compliance/problems
+	  related to the texture memory usage.
+
+	- Use triangles and quads strip: they are a LOT faster than sparse
+	  triangles and quads.
+
+	- The Voodoo driver supports the GL_EXT_paletted_texture. it works
+	  only with GL_COLOR_INDEX8_EXT, GL_RGBA palettes and the alpha value
+	  is ignored because this is a limitation of the the current Glide
+	  version and of the Voodoo hardware. See Mesa-3.1/3Dfx/demos/paltex.c for
+	  a demo of this extension.
+
+	- The Voodoo driver directly supports 3Dfx Global Palette extension.
+	  It was written for GLQuake and I think that it isn't a good idea
+	  to use this extension for any other purpose (it is a trick). See
+	  Mesa-3.1/3Dfx/demos/glbpaltex.c for a demo of this extension.
+
+	- The Voodoo driver chooses the screen resolution according to the
+	  requested window size. If you open a 640x480 window, you will get
+	  a 640x480 screen resolution, if you open a 800x600 window, you
+	  will get a 800x600 screen resolution, etc.
+	  Most GLUT demos support the '-geometry' option, so you can choose
+	  the screen resolution: 'tunnel -geometry 800x600'.
+	  Clearly, you Voodoo board must have enough framebuffer RAM (otherwise
+	  the window creation will fail).
+
+	- The glGetString(GL_RENDERER) returns more information
+          about the hardware configuration: "Mesa Glide <version>
+          <Voodoo_Graphics|Voodoo_Rush|UNKNOWN> <num> CARD/<num> FB/
+          <num> TM/<num> TMU/<NOSLI|SLI>"
+          where: <num> CARD is the card used for the current context,
+          <num> FB is the number of MB for the framebuffer,
+          <num> TM is the number of MB for the texture memory,
+          <num> TMU is the number of TMU. You can try to run
+          Mesa/demos/glinfo in order to have an example of the output.

+
+FAQ:
+----
+
+For a complete FAQ check the Bernd Kreimeier's Linux 3Dfx HOWTO
+available at http://www.gamers.org/dEngine/xf3D (it includes also
+a lot of informations not strictly related to Linux, so it can be
+useful also if you don't use Linux)
+
+1. What is 3Dfx?
+
+3Dfx Interactive, Inc. is the company which builds the VooDoo 3-D graphics
+chipset (and others) used in popular PC cards such as the Diamond Monster 3D
+and the Orchid Righteous 3D (more informations at http://www.3dfx.com).
+
+
+2. What is Glide?
+
+Glide is a "thin" programming interface for the 3Dfx hardware.  It was
+originally written for Windows/Intel but has been ported to Linux/Intel
+by Daryll Strauss.
+
+3Dfx, Inc. should be applauded for allowing the Linux version of Glide
+to be written.
+
+You can directly program with the Glide library if you wish.  You can
+obtain Glide from the "Developer" section of the 3Dfx website: www.3dfx.com
+There's a Linux/Glide newsgroup at news://news.3dfx.com/3dfx.glide.linux
+
+
+3. What is fxmesa?
+
+"fxmesa" is the name of the Mesa device driver for the 3Dfx Glide library.
+It was written by David Bucciarelli and others.  It works on both Linux
+and Windows.  Basically, it allows you to write and run OpenGL-style programs
+on the 3Dfx hardware.
+
+
+4. What is GLQuake?
+
+Quake is a very popular game from id software, Inc.  See www.idsoftware.com
+GLQuake is a version of Quake written for OpenGL.  There is now a Linux
+version of GLQuake with works with the Mesa/3Dfx/Glide combo.
+
+Here's what you need to run GLQuake on Linux:
+   PC with 100MHz Pentium or better
+   a 3Dfx-based card
+   Mesa 3.1 libraries:  libMesaGL.so  libMesaGLU.so
+   Glide 2.4 libraries:  libglide2x.so  libtexus.so
+   GLQuake for Linux.
+
+Also, the windows version of GLQuake works fine with the Mesa OpenGL32.dll,
+you have only to copy the Mesa-3.1/lib/OpenGL32.dll in the GLQuake directory
+in order to test 'MesaQuake'.
+
+
+5. What is GLUT?
+
+GLUT is Mark Kilgard's OpenGL Utility Toolkit.  It provides an API for
+writing portable OpenGL programs with support for multiple windows, pop-
+up menus, event handling, etc.
+
+Check the Mark's home page for more informations (http://reality.sgi.com/mjk_asd).
+
+Every OpenGL programmer should check out GLUT.
+
+GLUT on Linux uses GLX.
+
+
+6. What is GLX?
+
+GLX is the OpenGL extension to the X Window System.  I defines both a
+programming API (glX*() functions) and a network protocol.  Mesa implements
+an emulation of GLX on Linux.  A real GLX implementation would requires
+hooks into the X server.  The 3Dfx hardware can be used with GLX-based
+programs via the MESA_GLX_FX environment variable.
+
+
+7. Is the Voodoo driver able to use the 4Mb texture memory of
+the Pure3D boards ?
+
+Yes, the Voodoo driver v0.20 includes the support for Voodoo
+Graphics boards with more than 2Mb of texture memory.
+
+
+8. Do the Voodoo driver support the Voodoo Rush under Windows ?
+
+Yes, Diego Picciani has developed the support for the Voodoo
+Rush but David Bucciarelli has a Pure3D and a Monster3D and Brian Paul
+has a Monster3D, so the new versions of the Mesa/Voodoo sometime are
+not tested with the Voodoo Rush.
+
+
+9. Do the Voodoo driver support the Voodoo Rush under Linux ?
+
+No because the Linux Glide doesn't (yet) support the Voodoo Rush.
+
+
+10. Can I sell my Mesa/Voodoo based software and include
+a binary copy of the Mesa in order to make the software
+working out of the box ?
+
+Yes.
+
+
+11. Which is the best make target for compiling the Mesa for
+Linux GLQuake ('make linux-glide', 'make linux-386-glide', etc.) ?
+
+'make linux-386-opt-glide' for Voodoo1 and 'make linux-386-opt-V2-glide'
+for Voodoo2 boards because it doesn't include the '-fPIC'
+option (4-5% faster).
+
+
+12. Can I use a Mesa compiled with a 'make linux-386-opt-V2-glide'
+for my applications/programs/demos ?
+
+Yes, there is only one constrain: you can't run two Mesa applications
+at the some time. This isn't a big issue with the today Voodoo Graphics.

+AMIGA AMIWIN PORT of MESA: THE OPENGL SOFTWARE EMULATION
+========================================================
+Port by Victor Ng-Thow-Hing (victorng@dgp.toronto.edu) 
+Original Author (Brian Paul (brianp@ssec.wisc.edu)
+
+Dec.1 , 1995: Port of release Mesa 1.2.5
+ - Modifications made to minimize changes to Mesa distribution.
+
+Nov.25, 1995: Port of release Mesa 1.2.4
+
+
+HISTORY
+=======
+As a 3D graphics progammer, I was increasingly frustrated to see OpenGL 
+appearing on so many platforms EXCEPT the Amiga. Up to now, the task
+of porting OpenGL directly from native Amiga drawing routines seemed like
+a daunting task. However, two important events made this port possible.
+
+First of all, Brian Paul wrote Mesa, the OpenGL software emulator that 
+can be found on many platforms - except the Amiga and Atari (who cares 
+about the latter!). This was pretty ironic considering that Mesa was 
+originally prototyped on an Amiga! The second great event was when 
+Holger Kruse developed AmiWin, the X11R6 server for the Amiga (definitely 
+register for this great piece of software) and released a development kit
+so one could compile X programs with SAS/C.
+
+Since Mesa had X routines as its primitive drawing operations, this made
+a marriage of Mesa and Amiwin feasible. I copied over the sources from
+an ftp site, played with the code, wrote some Smakefiles, and voila, 
+I had OpenGL programs displaying on my Amiga.
+
+Although the speed is nothing to be impressed about, this port can be
+potentially useful to those who want to quickly test their code in
+wireframe or perhaps learn more about programming with the OpenGL API.
+
+I hope Amiga developers will continue to write excellent software for
+their machine, especially more X clients for Amiwin. If you have any 
+solutions so some of my problems in the porting notes, please send me
+some email!
+
+See you around,
+Vic.
+
+HOW TO CREATE THE LIBRARIES AND SAMPLE CODE
+===========================================
+
+Just run the shell script mklib.amiwin in the mesa directory. This will
+make all the libraries and copy them into the mesa/lib directory. If you
+don't want to compile everything, just go to the desired directory and
+type smake in that directory.
+
+Change any of the variables in the smakefiles as necessary. You will REQUIRE
+the Amiwin development kit to compile these libraries since you need X11.LIB
+and the shareable X libraries. Some examples require the AmiTCP4.0
+net.lib static link library and related header files for unix related
+header files and functions like sleep().
+
+HOW TO USE THE MESA LIBRARIES
+=============================
+
+Study the Smakefiles in the demos, samples and book directories for the
+proper SAS/C options and linkable libraries to use. Basically aux calls
+require Mesaaux.LIB, gl calls require MesaGL.LIB, glu calls MesaGLU.LIB,
+tk calls Mesatk.LIB. There is a preliminary port of MesaGLUT.LIB toolkit
+available in the lib directory with the other Mesa libraries. However, 
+it seems to cause crashes on some of the sample code. Someone else may want
+to attempt a more stable port.
+
+PORTING NOTES TO AMIWIN
+=======================
+
+My strategy of porting was to leave as much of the code untouched as
+possible. I surrounded any amiga specific changes with 
+#ifdef AMIWIN ... #endif or #ifndef AMIWIN ... #endif preprocessor
+symbols. The code  was ported on an Amiga 2000, with Fusion 40 accelerator
+and a Picasso II graphics card. The SAS/C 6.56 compiler was used, with
+the AmiWin 2.16 X development kit.
+
+All compilations were done for a 68040 CPU with 68882 math coprocessor for
+maximum  speed. Please edit the smakefile for other compilers.
+I wrote smakefiles for the directories I ported. I omitted the Windows
+and Widgets directories. The former is for MS Windows and the latter 
+requires Motif, which is not easily available for the Amiga.
+
+Here are the changes I did per directory:
+
+* mesa
+Nov. 25, 1995 v 1.2.4
+  - added a mklib.amiwin shell script that will make all the libraries and
+    sample code for Mesa
+  - created this readme file: readme.AMIGA
+
+* mesa/include
+Dec. 1, 1995 v 1.2.5

+                         Mesa / BeOS Information
+
+
+
+* Introduction
+
+Brian Paul added in Mesa 3.1 a driver for BeOS R4.5 operating system.
+This driver implements a clone of the BGLView class.  This class,
+derived from BView, allows OpenGL rendering into any BeOS window.  His
+driver was updated in Mesa 4.1 and again in version 6.1 by Philippe
+Houdoin, who's maintaining this driver since.
+
+Any application which uses the BGLView should be able to use Mesa
+instead of Be's OpenGL without changing any code.
+
+Since Be's OpenGL implementation (as of R5) is basically just the
+SGI sample implementation, it's pretty slow.  You'll see that Mesa
+is considerably faster.
+
+
+* Source Code
+
+The source code for the driver is in src/mesa/drivers/beos/ directory.
+It's not 100% finished at this time but many GLUT-based demos are
+working.  No optimizations have been made at this time.
+
+
+* Compiling
+
+Since Mesa 6.x, it can be build under BeOS with both the R5 builtin gcc version
+or more recent gcc versions available for BeOS, like this gcc version 2.95.3 for BeOS 
+you can find at http://www.bebits.com/app/2157.
+Anyway, keep in mind that to take full advantage of Mesa x86 optimizations, you better
+want to use gcc 2.95.3 or sooner versions...
+
+To build Mesa-powered BeOS libGL.so version, open an Terminal window,
+move to Mesa root folder and type this command:
+
+$ make beos
+
+Note that the "beos" argument is only needed the first time to setup build config.
+Next times, typing "make" will be enough.
+
+When it finishes the Mesa based libGL.so library for
+BeOS will be in the lib/ directory, along libglut.so library.
+Several demo/test programs should have been build too under progs/* folders.
+If it stop when building one of the progs/* programs, you may want to ignore it
+and force make to move on next target by adding the -k make option:
+
+$ cd progs
+$ make -k
+
+To install it as Be's default libGL.so replacement, put it in your 
+/boot/home/config/lib/ directory. All your GL/GLUT apps will use 
+the Mesa based then. 
+
+By default, it build a non-debug version library.
+The x86 (MMX, SSE and 3DNOW) optimizations are also supported for x86 target.
+For PowerPC BeOS flavor, sorry, Mesa don't have ppc (Altivec) optimizations
+yet.
+
+To build a DEBUG version, type instead this :
+
+$ DEBUG=1 make
+
+
+* Example Programs
+
+Look under progs/beos/ for some BGLView-based programs.
+You should find under progs/samples and progs/redbook directories GLUT-based programs too.
+They all should have been compiled along with the Mesa library.
+
+
+* GLUT
+
+A beta version of GLUT 3.7 port for BeOS, made by Jake Hamby, can be found at 
+http://anobject.com/jehamby/Code/Glut-3.7-x86.zip.
+This is the version currently included in Mesa source code, and
+build in lib/libglut.so.
+ 
+A previous 3.5 version of this GLUT BeOS port used to be available at
+http://home.beoscentral.com/jehamby/Glut-3.5-x86.zip.
+
+They're special versions of GLUT for the BeOS platform.  I don't
+believe Mark Kilgard's normal GLUT distribution includes BeOS
+support.
+
+
+* Special Features
+
+Mesa's implementation of the BGLView class has an extra member
+function:  CopySubBufferMESA().  It basically works like SwapBuffers()
+but it only copies a sub region from the back buffer to the front
+buffer.  This is a useful optimization for some applications.
+If you use this method in your code be sure that you check at runtime
+that you're actually using Mesa (with glGetString) so you don't
+cause a fatal error when running with Be's OpenGL.
+
+
+* Work Left To Do
+
+- BDirectWindow single buffering support is not implemented yet.
+- Color index mode is not implemented yet.
+- Reading pixels from the front buffer not implemented yet.
+- There is also a BGLScreen class in BeOS for full-screen OpenGL rendering.
+  This should also be implemented for Mesa.
+- Multiple renderers add-ons support, first step toward hardware acceleration
+  support.
+
+* Other contributors to this BeOS port
+
+Jake Hamby                      jhamby <at> anobject <dot> com
+Marcin Konicki                  ahwayakchih <at> neoni <dot> net
+Francois Revol                  revol <at> free <dot> fr
+Nathan Whitehorn                nathanw <at> uchicago <dot> edu
+
+
+* Older BeOS Driver
+
+Mesa 2.6 had an earlier BeOS driver.  It was based on Mesa's Off-screen
+rendering interface, not BGLView.  If you're interested in the older
+driver you should get Mesa 2.6.
+
+
+* BeOS and Glide
+
+Mesa 3.0 supported the 3Dfx/Glide library on Beos.  Download Mesa 3.0
+if interested.  Ideally, the 3Dfx/Glide support should be updated to
+work with the new Mesa 3.1 BGLView implementation.
+
+The Glide library hasn't been updated for BeOS R4 and newer, to my knowledge,
+as of February, 1999.

+                          Mesa Cygwin/X11 Information
+
+
+WARNING
+=======
+
+If you installed X11 (packages xorg-x11-devel and xorg-x11-bin-dlls ) with the 
+latest setup.exe from Cygwin the GL (Mesa) libraries and include are already 
+installed in /usr/X11R6. 
+
+The following will explain how to "replace" them.
+
+Installation
+============
+
+How to compile Mesa on Cygwin/X11 systems:
+
+1. Shared libs:
+    type 'make cygwin-sl'.
+
+    When finished, the Mesa DLL will be in the Mesa-x.y/lib/ and 
+    Mesa-x.y/bin directories.
+
+
+2. Static libs:
+    type 'make cygwin-static'.
+    When finished, the Mesa libraries will be in the Mesa-x.y/lib/ directory.
+
+Header and library files:
+   After you've compiled Mesa and tried the demos I recommend the following
+   procedure for "installing" Mesa.
+
+   Copy the Mesa include/GL directory to /usr/X11R6/include:
+	cp -a include/GL /usr/X11R6/include
+
+   Copy the Mesa library files to /usr/X11R6/lib:
+	cp -a lib/* /usr/X11R6ocal/lib
+
+   Copy the Mesa bin files (used by the DLL stuff) to /usr/X11R6/bin:
+	cp -a lib/cyg* /usr/X11R6/bin
+
+Xt/Motif widgets:
+   If you want to use Mesa or OpenGL in your Xt/Motif program you can build
+   the widgets found in either the widgets-mesa or widgets-sgi directories.
+   The former were written for Mesa and the later are the original SGI
+   widgets.  Look in those directories for more information.
+   For the Motif widgets you must have downloaded the lesstif package.
+
+
+Using the library
+=================
+
+Configuration options:
+   The file src/mesa/main/config.h has many parameters which you can adjust
+   such as maximum number of lights, clipping planes, maximum texture size,
+   etc.  In particular, you may want to change DEPTH_BITS from 16 to 32
+   if a 16-bit depth buffer isn't precise enough for your application.
+
+
+Shared libraries:
+   If you compile shared libraries (Win32 DLLS) you may have to set an 
+   environment variable to specify where the Mesa libraries are located.  
+   Set the PATH variable to include /your-dir/Mesa-2.6/bin.   
+   Otherwise, when you try to run a demo it may fail with a message saying 
+   that one or more DLL couldn't be found.
+
+
+Xt/Motif Widgets:
+   Two versions of the Xt/Motif OpenGL drawing area widgets are included:
+
+      widgets-sgi/	SGI's stock widgets
+      widgets-mesa/	Mesa-tuned widgets
+
+   Look in those directories for details
+
+
+Togl:
+   Togl is an OpenGL/Mesa widget for Tcl/Tk.
+   See http://togl.sourceforge.net for more information.
+
+
+
+X Display Modes:
+   Mesa supports RGB(A) rendering into almost any X visual type and depth.
+
+   The glXChooseVisual function tries its best to pick an appropriate visual
+   for the given attribute list.  However, if this doesn't suit your needs
+   you can force Mesa to use any X visual you want (any supported by your
+   X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL
+   environment variables.  When an RGB visual is requested, glXChooseVisual
+   will first look if the MESA_RGB_VISUAL variable is defined.  If so, it
+   will try to use the specified visual.  Similarly, when a color index
+   visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL
+   variable.
+
+   The format of accepted values is:  <visual-class> <depth>
+   Here are some examples:
+
+   using the C-shell:
+	% setenv MESA_RGB_VISUAL "TrueColor 8"		// 8-bit TrueColor
+	% setenv MESA_CI_VISUAL "PseudoColor 12"	// 12-bit PseudoColor
+	% setenv MESA_RGB_VISUAL "PseudoColor 8"	// 8-bit PseudoColor
+
+   using the KornShell:
+	$ export MESA_RGB_VISUAL="TrueColor 8"
+	$ export MESA_CI_VISUAL="PseudoColor 12"
+	$ export MESA_RGB_VISUAL="PseudoColor 8"
+
+
+Double buffering:
+   Mesa can use either an X Pixmap or XImage as the backbuffer when in
+   double buffer mode.  Using GLX, the default is to use an XImage.  The
+   MESA_BACK_BUFFER environment variable can override this.  The valid
+   values for MESA_BACK_BUFFER are:  Pixmap and XImage (only the first
+   letter is checked, case doesn't matter).
+
+   A pixmap is faster when drawing simple lines and polygons while an
+   XImage is faster when Mesa has to do pixel-by-pixel rendering.  If you
+   need depth buffering the XImage will almost surely be faster.  Exper-
+   iment with the MESA_BACK_BUFFER variable to see which is faster for
+   your application.  
+
+
+Colormaps:
+   When using Mesa directly or with GLX, it's up to the application writer
+   to create a window with an appropriate colormap.  The aux, tk, and GLUT
+   toolkits try to minimize colormap "flashing" by sharing colormaps when
+   possible.  Specifically, if the visual and depth of the window matches
+   that of the root window, the root window's colormap will be shared by
+   the Mesa window.  Otherwise, a new, private colormap will be allocated.
+
+   When sharing the root colormap, Mesa may be unable to allocate the colors
+   it needs, resulting in poor color quality.  This can happen when a
+   large number of colorcells in the root colormap are already allocated.
+   To prevent colormap sharing in aux, tk and GLUT, define the environment
+   variable MESA_PRIVATE_CMAP.  The value isn't significant.
+
+
+Gamma correction:
+   To compensate for the nonlinear relationship between pixel values
+   and displayed intensities, there is a gamma correction feature in
+   Mesa.  Some systems, such as Silicon Graphics, support gamma
+   correction in hardware (man gamma) so you won't need to use Mesa's
+   gamma facility.  Other systems, however, may need gamma adjustment
+   to produce images which look correct.  If in the past you thought
+   Mesa's images were too dim, read on.
+
+   Gamma correction is controlled with the MESA_GAMMA environment
+   variable.  Its value is of the form "Gr Gg Gb" or just "G" where
+   Gr is the red gamma value, Gg is the green gamma value, Gb is the
+   blue gamma value and G is one gamma value to use for all three
+   channels.  Each value is a positive real number typically in the
+   range 1.0 to 2.5.  The defaults are all 1.0, effectively disabling
+   gamma correction.  Examples using csh:
+
+	% setenv MESA_GAMMA "2.3 2.2 2.4"	// separate R,G,B values
+	% setenv MESA_GAMMA "2.0"		// same gamma for R,G,B
+
+   The demos/gamma.c program may help you to determine reasonable gamma
+   value for your display.  With correct gamma values, the color intensities
+   displayed in the top row (drawn by dithering) should nearly match those
+   in the bottom row (drawn as grays).
+
+   Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well
+   on HP displays using the HP-ColorRecovery technology.
+
+   Mesa implements gamma correction with a lookup table which translates
+   a "linear" pixel value to a gamma-corrected pixel value.  There is a
+   small performance penalty.  Gamma correction only works in RGB mode.
+   Also be aware that pixel values read back from the frame buffer will
+   not be "un-corrected" so glReadPixels may not return the same data
+   drawn with glDrawPixels.
+
+   For more information about gamma correction see:
+   http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html
+
+
+Overlay Planes
+
+   Overlay planes in the frame buffer are supported by Mesa but require
+   hardware and X server support.  To determine if your X server has
+   overlay support you can test for the SERVER_OVERLAY_VISUALS property:
+
+	xprop -root | grep SERVER_OVERLAY_VISUALS
+
+
+HPCR glClear(GL_COLOR_BUFFER_BIT) dithering
+
+   If you set the MESA_HPCR_CLEAR environment variable then dithering
+   will be used when clearing the color buffer.  This is only applicable
+   to HP systems with the HPCR (Color Recovery) system.
+
+
+Extensions
+==========
+   There are three Mesa-specific GLX extensions at this time.
+
+   GLX_MESA_pixmap_colormap 
+
+      This extension adds the GLX function:
+
+         GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
+                                           Pixmap pixmap, Colormap cmap )
+
+      It is an alternative to the standard glXCreateGLXPixmap() function.
+      Since Mesa supports RGB rendering into any X visual, not just True-
+      Color or DirectColor, Mesa needs colormap information to convert RGB
+      values into pixel values.  An X window carries this information but a
+      pixmap does not.  This function associates a colormap to a GLX pixmap.
+      See the xdemos/glxpixmap.c file for an example of how to use this
+      extension.
+
+   GLX_MESA_release_buffers
+
+      Mesa associates a set of ancillary (depth, accumulation, stencil and
+      alpha) buffers with each X window it draws into.  These ancillary
+      buffers are allocated for each X window the first time the X window
+      is passed to glXMakeCurrent().  Mesa, however, can't detect when an
+      X window has been destroyed in order to free the ancillary buffers.
+
+      The best it can do is to check for recently destroyed windows whenever
+      the client calls the glXCreateContext() or glXDestroyContext()
+      functions.  This may not be sufficient in all situations though.
+
+      The GLX_MESA_release_buffers extension allows a client to explicitly
+      deallocate the ancillary buffers by calling glxReleaseBuffersMESA()
+      just before an X window is destroyed.  For example:
+
+         #ifdef GLX_MESA_release_buffers
+            glXReleaseBuffersMESA( dpy, window );
+         #endif
+         XDestroyWindow( dpy, window );
+
+      This extension is new in Mesa 2.0.
+
+   GLX_MESA_copy_sub_buffer
+
+      This extension adds the glXCopySubBufferMESA() function.  It works
+      like glXSwapBuffers() but only copies a sub-region of the window
+      instead of the whole window.
+
+      This extension is new in Mesa version 2.6
+
+
+
+Summary of X-related environment variables:
+   MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only)
+   MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only)
+   MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only)
+   MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only)
+   MESA_GAMMA - gamma correction coefficients (X only)

+                     DirectX 6 Driver for Mesa 3.0
+
+
+This software is distributed under the terms of the GNU Library
+General Public License, see the LICENSE file for details.
+
+
+
+What do you need ?
+------------------
+
+	- A PC with a DirectX 6 video driver installed.
+
+	- Mesa 3.0
+
+	- The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine).
+	  The Voodoo2 requires the Glide library 2.51. The Glide 3.0 is not
+	  compatible with the Glide 2.x so it doesn't work with the current
+	  version of the driver;
+
+	- Visual C++ 5.0 is only compiler test but others should be ok with
+       changes to the makefiles (CFLAGS/LFLAGS).
+
+	- DirectX 6 SDK (was a MS download but not sure if still available).
+
+	- SoftIce or another debugger that will get DPF's is nice.
+
+
+Tested on:
+----------
+	Windows 95
+  	Windows 98
+	Windows NT 5.0 (beta 2)
+
+
+What is able to do ?
+--------------------
+
+	- the driver will try and use DirectX to rasterize the OpenGL primitives
+	that are sent to the driver.  The driver will fall back to SW  if the rendering 
+	context is too big.  The fallback to SW still uses DirectDraw.  If the driver
+	fails to support and operation (accum, stencil, etc) then it will try and get
+	Mesa to render it in SW.  DirectX 6 features that are unsupported by the 
+	installed DirectX 6 driver will be mapped to some other best fit feature.
+
+
+How to compile:
+---------------
+
+	These instructions assume you have Visual C++ installed.
+
+	  You might need to increase you enviroment space.  You can do this by 
+	adding the following statement to you config.sys.
+
+	shell=C:\COMMAND.COM C:\ /p /e:8198
+
+	  Next setup you compiler enviroment by running vcvars32.bat in the Visual C++
+ 	'bin' directoy.
+
+	c:\DevStudio\VC\bin\vcvars32.bat
+
+	  Modify the D3D makefile to point at your SDK install.  Example has the SDK
+	installed on my 'f' drive in the root.
+
+	file: \Mesa-3.0\src\makefile.d3d
+
+	SDKROOT=f:\mssdk
+
+	  Now you can simply make the project.  If you look in the makefile you can see
+	I have some different targets like 'install'.  
+
+	nmake /f makefile.d3d
+
+
+FAQ:
+----
+
+	1) I don't think the driver is using my DirectX driver.
+
+ 	  This maybe true as the current version will only select the Primary D3D driver
+	installed.  If you 3D card is the secondary (3dfx) then your out of luck for this
+	release.
+
+	2) The driver seems like its not HW accelerated.
+
+	  If you have a video card with limited memory then you might want to try and 
+	change your destop resolution to a low setting (640x480x16) so that the 3D part
+	of the card has more resources.  Remeber the driver can't make the card better...
+
+	3) Nothing works.
+
+	  Make sure you have a DirectX '6' driver installed.  Check you driver docs for this
+	info or use the SDK info utilities.
+	  The final 'dll' is named opengl32.dll and is either in the same directory as the 
+	OpenGL program or in your system directory (x:\windows\system or x:\winnt\system32).
+	  Check your destop resolution.  Most DirectX 6 drivers will only support 16bit and
+	32bit color depth.  To find out for sure you can check the DirectX Info Viewer in
+	the SDK.
+	  
+
+	4) Rendering doesn't look right.
+
+	  Sometimes this is because the card doesn't support a feature that that is required.
+	This is usually due to unsupported alpha functions (test/blend) or texture mapping.
+	Some cards suffer from too small of an alpha channel.  The driver does its best to
+	fallback on unsupported features.  This is not to say the driver may not have a bug(s).
+
+	5) Textures look bad.
+

+			Mesa 6.3 DOS/DJGPP Port v1.7
+			~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+
+Description:
+~~~~~~~~~~~~
+
+Well, guess what... this is the DOS port of Mesa 6.3, for DJGPP fans... Whoa!
+The driver has its origins in ddsample.c, written by Brian Paul and found by me
+in Mesa 3.4.2.
+
+
+
+Legal:
+~~~~~~
+
+Mesa copyright applies, provided this package is used within Mesa. For anything
+else, see GPL.
+
+
+
+Installation:
+~~~~~~~~~~~~~
+
+Unzip and type:
+
+	make -f Makefile.DJ [OPTIONS...]
+
+Available options:
+
+     Environment variables:
+	CPU		optimize for the given processor.
+			default = pentium
+	GLU=[mesa|sgi]	specify GLU directory; can be `sgi' (requires GNU/C++)
+			or `mesa'.
+			default = mesa
+	GLIDE		path to Glide3 SDK; used with FX.
+			default = $(TOP)/glide3
+	FX=1		build for 3dfx Glide3. Note that this disables
+			compilation of most DMesa code and requires fxMesa.
+			As a consequence, you'll need the DJGPP Glide3
+			library to build any application.
+			default = no
+	X86=1		optimize for x86 (if possible, use MMX, SSE, 3DNow).
+			default = no
+
+     Targets:
+	all:		build everything
+	libgl:		build GL
+	libglu:		build GLU
+	libglut:	build GLUT
+	clean:		remove object files
+	realclean:	remove all generated files
+
+
+
+Tested on:
+	CPU:		AMD Athlon XP 1800+
+	Mainboard:	GA-7VTXE w/ 512 MB DDRAM
+	Video card:	Voodoo5 6000 AGP w/ 128 MB SDRAM
+	DJGPP:		djdev 2.04 + gcc v3.4.3 + make v3.80
+	OS:		DOS and Win98SE
+
+
+
+FAQ:
+~~~~
+
+1. Compilation
+
+   Q) `make' barfs and exits because it cannot find some stupid file.
+   A) You need LFN support.
+   A) When compiling for Glide (FX=1), pay attention to Glide path.
+
+   Q) Libraries built OK, but linker complains about `vsnprintf' every time I
+      compile some demo.
+   A) Upgrade to DJGPP 2.04.
+   A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
+   A) Patch `src/mesa/main/imports.c' with the following line:
+	#define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
+      This hack should be safe in 90% of the cases, but if anything goes wrong,
+      don't come back to me crying.
+
+   Q) `make' complains about DXE3 or something, yet it builds the libraries.
+   A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
+      DJGPP distro, or download the separate package from my web page. Read the
+      DXE3 documentation on how to use them.
+   A) When compiling for Glide (FX=1), make sure `glide3x.dxe' can be found in
+      LD_LIBRARY_PATH (or top `lib' directory).
+
+2. Using Mesa for DJGPP
+
+   Q) Every test I tried crashes badly.
+   A) If you have compiled with SSE and you're running under plain DOS, you
+      have to disable SSE at run-time. See environment variables below.
+
+   Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
+   A) Is that a question? If you have a 3dfx Voodoo (any model), you're
+      lucky (check http://sourceforge.net/projects/glide for the DJGPP port).
+      If you haven't, sorry; everything is done in software. Suggestions?
+
+   Q) I tried to set refresh rate w/ DMesa, but without success.
+   A) Refresh rate control works only for VESA 3.0 and the 3dfx driver (in
+      which case FX_GLIDE_REFRESH will be overwritten if it is defined and
+      is not 0).
+
+   Q) I made a simple application and it does nothing. It exits right away. Not
+      even a blank screen.
+   A) Pure software drivers (VESA/VGA/NUL) support only double-buffered modes.
+   A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
+      lazy programmer and I found that the easiest way to keep buffer handling
+      at peak performance ;-).
+
+   Q) I'm getting a "bad font!" fatal error.
+   A) Always use GLUT_STROKE_* and GLUT_BITMAP_* constants when dealing with
+      GLUT fonts. If you're using `glut.dxe', then make sure GLUT_STROKE_* and
+      GLUT_BITMAP_* are mapped to integer constants, not to the actual font
+      address (same mechanism used for Win32 _DLL).
+
+   Q) What is NUL driver good for, if I don't get any output at all?
+   A) For debugging. The NUL driver is very much like OSMesa. Everything is
+      done just the same as VESA/VGA drivers, only it doesn't touch your video
+      hardware. You can query the actual buffer by issuing:
+	DMesaGetIntegerv(DMESA_GET_BUFFER_ADDR, &buffer);
+      and dump it to a file.
+
+   Q) How do I query for a list of available video modes to choose as a visual?
+   A) This is an ugly hack, for which I'm sure I'll burn in hell.
+      First, query for a list of modes:
+	n = DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, NULL);
+      If `n' is strictly positive, you allocate an array of pointers to a given
+      struct (which is guaranteed to be extended only - not changed in future):
+	struct {
+		int xres, yres;
+		int bpp;
+	} **l = malloc(n * sizeof(void *));
+      Now pass the newly allocated buffer to fill in:
+	DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, (GLint *)l);
+      And collect the info:
+	for (i = 0; i < n; i++) {
+	    printf("%dx%d:%d\n", l[i]->xres, l[i]->yres, l[i]->bpp);
+	}
+
+   Q) The GLUT is incomplete.
+   A) See below.
+
+
+
+libGLUT (the toolkit):
+~~~~~~~~~~~~~~~~~~~~~~
+
+Well, this "skeletal" GLUT implementation was taken from AllegGL project and
+heavily changed. Thanks should go to Bernhard Tschirren, Mark Kilgard, Brian
+Paul and probably others (or probably not ;-). GLUT functionality will be
+extended only on an "as needed" basis.
+
+GLUT talks to hardware via PC_HW package which was put together from various
+pieces I wrote long time ago. It consists from the keyboard, mouse and timer
+drivers.
+
+My keyboard driver used only scancodes; as GLUT requires ASCII values for keys,
+I borrowed the translation tables (and maybe more) from Allegro -- many thanks
+to Shawn Hargreaves et co. Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users)
+will shut down the GLUT engine unconditionally: it will raise SIGINT, which in
+turn will (hopefully) call the destructors, thus cleaning up your/my mess ;-)
+NB: since the DJGPP guys ensured signal handlers won't go beyond program's
+space (and since dynamic modules shall) the SIGINT can't be hooked (well, it
+can, but it is useless), therefore you must live with the 'Exiting due to
+signal SIGINT' message...
+
+The mouse driver is far from complete (lack of drawing, etc), but is enough to
+make almost all the demos work. Supports the CuteMouse WheelAPI.
+
+The timer is pretty versatile for it supports multiple timers with different
+frequencies. While not being the most accurate timer in the known universe, I
+think it's OK. Take this example: you have timer A with a very high rate, and
+then you have timer B with very low rate compared to A; now, A ticks OK, but
+timer B will probably loose precision!
+
+As an addition, stdout and stderr are redirected and dumped upon exit. This
+means that `printf' can be safely called during graphics. A bit of a hack, I
+know, because all messages come in bulk, but I think it's better than nothing.
+"Borrowed" from LIBRHUTI (Robert Hoehne).
+
+Window creating defaults: (0, 0, 300, 300), 16bpp. However, the video mode is
+chosen in such a way that first window will fit. If you need high resolution
+with small windows, set initial position far to the right (or way down); then
+you can move them back to any position right before the main loop.
+
+
+
+Environment variables:
+~~~~~~~~~~~~~~~~~~~~~~
+	DMESA_NULDRV		- (any value) force NUL driver
+	GLUT_FPS		- print frames/second statistics to stderr
+	MESA_NO_SSE		- (any value) safe option under pure DOS
+	DMESA_GLUT_REFRESH	- set vertical screen refresh rate (VESA3)
+	DMESA_GLUT_BPP		- set default bits per pixel (VGA needs 8)
+	DMESA_GLUT_ALPHA	- set default alpha bits (8)
+	DMESA_GLUT_DEPTH	- set default depth bits (16)
+	DMESA_GLUT_STENCIL	- set default stencil bits (8)
+	DMESA_GLUT_ACCUM	- set default accum bits (16)
+

+Mesa 3.0 for LynxOS builds in the following way:
+
+make lynxos
+
+This will build all the libraries and demo applications. You should have 
+around 400 megabytes free for everything since everything is done with 
+static
+libraries.
+
+Before using this make file however, you should perform the following 
+actions:
+0) cd to the Mesa-3.0 directory
+1) Copy the GL directory under the include directory to /usr/include.
+2) Copy the files in the lib directory to /lib.
+3) Make links so that the Mesa libraries look like ordinary OpenGL 
+libraries
+in /lib. This is important for compatibility with other OpenGL apps. This
+is done as follows:
+
+cd /lib
+ln -s libMesaGL.a libGL.a
+ln -s libMesaGLU.a libGLU.a
+
+Mesa 3.0 includes the GLUT (GL Utility Toolkit) by default.
+The demo applications are done using this toolkit.
+
+Mesa makefiles for building their apps could be used as well, but the
+following one is much more concise. Note that the order of the X libraries
+is important to the linker so that all symbols get resolved correctly.
+Changing the order may result in having to list a library twice to make
+sure all linkages are made correctly.

+*******************************************************************************
+The Mingw port for Mesa 3-D Graphics Library was created August 30, 1998 by Paul Garceau.
+
+Updated January 13, 2000; June 3, 2005 -- Paul Garceau <pgarceau@users.sourceforge.net>
+
+DISCLAIMER:  I make this port of the Mesa 3-D Graphics Library as a service
+to the general public.  I can, in no way support or make any guarantee that the
+build will work for your system.
+
+Acknowledgements:
+
+	Daniel Borca, whose work and commitment to maintaining the Mingw port of the Mesa 3-D Graphics Library has been, and will continue to be greatly appreciated by an overworked and underpaid developer such as myself.
+	Without the creative inspiration and personal commitment provided by Mumit Khan, Jan-Jaap Vanderhagen and Colin Peters, Mingw would never have existed.  	Acknowledgements also need to be given to all of the developers who have worked on Mingw, Mesa and Msys over the years.
+	Last, but certainly far from the least, Brian Paul, who has dedicated at least the last seven or eight years of his life to making Mesa 3-D Graphics Library what it is today and managing the development for all of those years.
+*********************************************************************************
+
+Greetings,
+
+	Feel free to modify or change things related to the Mingw build as you see fit, just remember that, the author of the current build may not be able to support any modifications you might want to make to the files which have been included for the build.
+
+Mesa core components are licensed under XFree-86 (for more on licensing of Mesa 3-D Graphics Library, check out the Mesa homepage (http://www.mesa3d.org).
+
+The Mingw generated libraries themselves are licensed under the GNU-LGPL license.  Source code for Mingw can be found at http://www.mingw.org.  For licensing terms on Mingw, please visit http://www.mingw.org.
+
+	It is recommended that you use the latest "stable" release of Mingw.  "Candidates" are beta testing distributions for Mingw.  Mingw is available at http://www.mingw.org.
+
+	This build has been tested under WinNT4/SP6.  Win9x and WinNT5 remain untested by me.  I have not tested any of the demos included with Mesa3d.
+
+Installation:
+
+	This readme assumes that you already have extracted the necessary files to a working directory/folder that Mingw can use to build the Mesa3D libraries and that you know where that directory/folder is located on your Windows system.  If you have any questions about how to set things up properly which is specific to Mesa3D, the folks on the Mesa3D mailing lists (http://www.mesa3d.org) would probably be happy to assist you.  Also you can probably ask anyone on the Mingw mailing lists for any questions specific to Mingw (http://www.mingw.org)
+
+Targets and Environment variables used for Mingw build:
+
+	Before going into the actual build of the libraries, here is a list of available targets for the make process:
+
+	"all" or "libgl"  -- this target will build libopengl.a, a static library.  It will not build the demos, etc.
+
+	clean -- this target will clean up most of the Mesa 3-D Graphics Library/object code from your hard drive.
+
+	realclean -- this target will clean up all of the Mesa 3D Graphics Library and the Mesa object code that it can find.
+
+	Environment Variables:
+
+	The environment variables are used to determine what sort of graphics driver support needs to be included in the finished Mesa 3-D Graphics Library.
+
+	GLIDE		path to Glide3 SDK; used with FX.
+			default = $(TOP)/glide3
+	FX=1		build for 3dfx Glide3. Note that this disables
+			compilation of most WMesa code and requires fxMesa.
+			As a consequence, you'll need the Win32 Glide3
+			library to build any application.
+			default = no
+	ICD=1		build the installable client driver interface
+			(windows opengl driver interface)
+			default = no
+	X86=1		optimize for x86 (if possible, use MMX, SSE, 3DNow).
+			default = no
+
+	
+Running the Build:
+
+	Launch Mingw.
+	From the Windows Command Prompt:
+	Set Environment Variables (as needed).
+	"cd" to your Mesa3D 'root' directory.
+	Enter "mingw32-make -f makefile.mgw <target>
+
+	That's all there is to it.
+
+	Enjoy!

+
+
+This document is a preliminary introduction to help you get

+
+
+
+Version 0.1 (Yes it's very alpha code so be warned!)
+Contributors: 
+  Emil Briggs    	(briggs@bucky.physics.ncsu.edu)
+  David Bucciarelli 	(tech.hmw@plus.it)
+  Andreas Schiffler 	(schiffler@zkm.de)
+
+
+
+1. Requirements:
+     Mesa 3.0.
+     An SMP capable machine running Linux 2.x
+     libpthread installed on your machine.
+
+
+2. What does MITS stand for?
+     MITS stands for Mesa Internal Threading System. By adding
+     internal threading to Mesa it should be possible to improve
+     performance of OpenGL applications on SMP machines.
+
+
+3. Do applications have to be recoded to take advantage of MITS?
+     No. The threading is internal to Mesa and transparent to
+     applications.
+
+
+4. Will all applications benefit from the current implementation of MITS?
+     No. This implementation splits the processing of the vertex buffer
+     over two threads. There is a certain amount of overhead involved
+     with the thread synchronization and if there is not enough work
+     to be done the extra overhead outweighs any speedup from using
+     dual processors. You will not for example see any speedup when
+     running Quake because it uses GL_POLYGON and there is only one
+     polygon for each vertex buffer processed. Test results on a
+     dual 200 Mhz. Pentium Pro system show that one needs around
+     100-200 vertices in the vertex buffer before any there is any
+     appreciable benefit from the threading.
+
+
+5. Are there any parameters that I can tune to try to improve performance.
+     Yes. You can try to vary the size of the vertex buffer which is
+     define in VB_MAX located in the file src/vb.h from your top level
+     Mesa distribution. The number needs to be a multiple of 12 and
+     the optimum value will probably depend on the capabilities of
+     your machine and the particular application you are running.
+
+
+6. Are there any ways I can modify the application to improve its
+   performance with the MITS?
+     Yes. Try to use as many vertices between each Begin/End pair
+     as possbile. This will reduce the thread synchronization
+     overhead.
+
+
+7. What sort of speedups can I expect?
+     On some benchmarks performance gains of up to 30% have been
+     observerd. Others may see no gain at all and in a few rare
+     cases even some degradation.
+
+
+8. What still needs to be done?
+     Lots of testing and benchmarking.
+     A portable implementation that works within the Mesa thread API.
+     Threading of additional areas of Mesa to improve performance
+     even more.
+
+
+
+Installation:
+
+   1. This assumes that you already have a working Mesa 3.0 installation
+      from source.
+   2. Place the tarball MITS.tar.gz in your top level Mesa directory.
+   3. Unzip it and untar it. It will replace the following files in
+      your Mesa source tree so back them up if you want to save them.
+
+
+	 README.MITS
+         Make-config
+	 Makefile
+	 mklib.glide
+         src/vbxform.c
+	 src/vb.h
+
+   4. Rebuild Mesa using the command
+
+          make linux-386-glide-mits

+                           2) Building from sources

+
+
+1) Binary release
+
+   Though the Mesa sources should build in a quite reasonable time even on
+   a 585 class machine a binary relase is available (check topic 4) for an URL)
+   This package includes:
+
+     - lib/MesaGL.dll,  MesaGL.a
+     - lib/MesaGLU.dll, MesaGLU.a
+     - lib/glut.dll,    glut.a
+     - include/GL/*.h
+
+    Installing this in your XFree86 tree will enable you to build and
+    run all applications compatible with Mesa (and the current DLL
+    interface, of course ;-)
+    As usual the OMF-style libraries can be created using emxomf.
+    (e.g. "emxomf foo.a"  creates the foo.lib omf-style library).
+    The static libraries are rarely used and you have to rebuild
+    Mesa to get them. They're a supported target, so you get
+    them in a straightforward way (see below).
+
+    The testing of these libraries was limited to the supplied
+    demos/examples and a quite small number of third-party apps.
+    No warranty ... as usual ...  ;-)
+
+
+2)  Instructions to build Mesa 3.x for XFree86/OS2 from sources:
+
+    Except the official Mesa source distribution you need:
+      - a recent version of XFree86 (3.3.x or above) including
+        the programming libraries
+      - EMX 0.9c (0.9d might work, never checked)
+      - GNU make
+      - REXX (!)
+
+    The creation of the DLLs as well as of the static libraries
+    (if you want to have them) is handled in "mklib-emx.cmd",
+    a small REXX script. Perhaps not the best idea, but this
+    way it fits best in the scheme used to build libraries
+    on all platforms in Mesa 3.x.
+
+    To actually build the libraries and demos, check mklib-emx.cmd
+    and modify it as desired. Then type
+      make os2-x11
+    and wait for completion ;-)
+
+
+3)  History
+
+    Initially Darren Abbott (abbott@hiwaay.net) ported Mesa versions 2.x
+    to XFree86 OS/2. This port might still be available from 
+       http://fly.HiWAAY.net/~abbott/xfree86-os2/xfree86.html
+
+    The current port picked up things during the beta test for 3.0. 
+    No major changes in the source were done. The build mechanism under OS/2
+    has been made very similar to other platforms (if you treat mklib-emx.cmd
+    as a "black box").
+    Advantage is that X/2 is now a valid target and all files are
+    integrated in the official source distribution.
+    Disadvantage is that this port (i.e. the DLLs' interface itself) is
+    definitly NOT COMPATIBLE to those of version 2.x. 
+    It's uncertain whether this would be at all possible but since there
+    a _very_ few those apps it's not worth to find out anyway.
+    Also some libs (MesaTK, MesaAUX) are withdrawn from the Mesa distribution,
+    and accordingly from the OS/2 port.
+
+4) Todo
+
+    By now binary compatiblity is ensured by using the function names
+    as entry points instead of ordinals. This might cost performance and
+    is subject to change in future. In addition the supplied X86 assembler
+    source is not used yet.
+
+5)  Mesa Home Page
+
+    You can get the source code and more information about Mesa from
+       http://www.mesa3d.org/
+
+    The OS/2 ports should be available from
+       http://r350.ee.ntu.edu.tw/~hcchu/os2/ports

+             Info on using Mesa 3.0 with Linux Quake I and Quake II
+
+
+
+Disclaimer
+----------
+
+I am _not_ a Quake expert by any means.  I pretty much only run it to
+test Mesa.  There have been a lot of questions about Linux Quake and
+Mesa so I'm trying to provide some useful info here.  If this file
+doesn't help you then you should look elsewhere for help.  The Mesa
+mailing list or the news://news.3dfx.com/3dfx.linux.glide newsgroup
+might be good.
+
+Again, all the information I have is in this file.  Please don't email
+me with questions.
+
+If you have information to contribute to this file please send it to
+me at brianp@elastic.avid.com
+
+
+
+Linux Quake
+-----------
+
+You can get Linux Quake from http://www.idsoftware.com/
+
+Quake I and II for Linux were tested with, and include, Mesa 2.6.  You
+shouldn't have too many problems if you simply follow the instructions
+in the Quake distribution.
+
+
+
+RedHat 5.0 Linux problems
+-------------------------
+
+RedHat Linux 5.x uses the GNU C library ("glibc" or "libc6") whereas
+previous RedHat and other Linux distributions use "libc5" for its
+runtime C library.
+
+Linux Quake I and II were compiled for libc5.  If you compile Mesa
+on a RedHat 5.x system the resulting libMesaGL.so file will not work
+with Linux Quake because of the different C runtime libraries.
+The symptom of this is a segmentation fault soon after starting Quake.
+
+If you want to use a newer version of Mesa (like 3.x) with Quake on
+RedHat 5.x then read on.
+
+The solution to the C library problem is to force Mesa to use libc5.
+libc5 is in /usr/i486-linux-libc5/lib on RedHat 5.x systems.
+
+Emil Briggs (briggs@tick.physics.ncsu.edu) nicely gave me the following
+info:
+
+>   I only know what works on a RedHat 5.0 distribution. RH5 includes
+> a full set of libraries for both libc5 and glibc. The loader ld.so
+> uses the libc5 libraries in /usr/i486-linux-libc5/lib for programs
+> linked against libc5 while it uses the glibc libraries in /lib and
+> /usr/lib for programs linked against glibc.
+> 
+> Anyway I changed line 41 of mklib.glide to
+>     GLIDELIBS="-L/usr/local/glide/lib -lglide2x -L/usr/i486-linux-libc5/lib"
+> 
+> And I started quake2 up with a script like this
+> #!/bin/csh
+> setenv LD_LIBRARY_PATH /usr/i486-linux-libc5/lib
+> setenv MESA_GLX_FX f
+> ./quake2 +set vid_ref gl
+> kbd_mode -a
+> reset
+
+
+I've already patched the mklib.glide file.  You'll have to start Quake
+with the script shown above though.

+Daryll Strauss writes:
+
+Here's my thoughts on the problem. On a RH 5.x system, you can NOT build
+a libc5 executable or library. Red Hat just doesn't include the right
+stuff to do it.
+
+Since Quake is a libc5 based application, you are in trouble. You need
+libc5 libraries.
+
+What can you do about it? Well there's a package called gcc5 that does
+MOST of the right stuff to compile with libc5. (It brings back older
+header files, makes appropriate symbolic links for libraries, and sets
+up the compiler to use the correct directories) You can find gcc5 here: 
+ftp://ecg.mit.edu/pub/linux/gcc5-1.0-1.i386.rpm
+
+No, this isn't quite enough. There are still a few tricks to getting
+Mesa to compile as a libc5 application. First you have to make sure that
+every compile uses gcc5 instead of gcc. Second, in some cases the link
+line actually lists -L/usr/lib which breaks gcc5 (because it forces you
+to use the glibc version of things)
+
+If you get all the stuff correctly compiled with gcc5 it should work.
+I've run Mesa 3.0B6  and its demos in a window with my Rush on a Red Hat
+5.1 system. It is a big hassle, but it can be done. I've only made Quake
+segfault, but I think that's from my libRush using the wrong libc. 
+
+Yes, mixing libc5 and glibc is a major pain. I've been working to get
+all my libraries compiling correctly with this setup. Someone should
+make an RPM out of it and feed changes back to Brian once they get it
+all working. If no one else has done so by the time I get the rest of my
+stuff straightened out, I'll try to do it myself.

+Mesa Threads README
+-------------------
+
+Thread safety was introduced in Mesa 2.6 by John Stone and
+Christoph Poliwoda.
+
+It was redesigned in Mesa 3.3 so that thread safety is
+supported by default (on systems which support threads,
+that is).  There is no measurable penalty on single
+threaded applications.
+
+NOTE that the only _driver_ which is thread safe at this time
+is the OS/Mesa driver!
+
+
+At present the mthreads code supports three thread APIS:
+  1) POSIX threads (aka pthreads).
+  2) Solaris / Unix International threads.
+  3) Win32 threads (Win 95/NT).
+
+Support for other thread libraries can be added src/glthread.[ch]
+
+
+In order to guarantee proper operation, it is
+necessary for both Mesa and application code to use the same threads API.
+So, if your application uses Sun's thread API, then you should build Mesa
+using one of the targets for Sun threads.
+
+The mtdemos directory contains some example programs which use 
+multiple threads to render to osmesa rendering context(s).
+
+Linux users should be aware that there exist many different POSIX
+threads packages. The best solution is the linuxthreads package
+(http://pauillac.inria.fr/~xleroy/linuxthreads/) as this package is the
+only one that really supports multiprocessor machines (AFAIK). See
+http://pauillac.inria.fr/~xleroy/linuxthreads/README for further
+information about the usage of linuxthreads.
+
+If you are interested in helping with thread safety work in Mesa
+join the Mesa developers mailing list and post your proposal.
+

+VMS support contributed by Jouk Jansen (joukj@hrem.stm.tudelft.nl)
+
+
+The latest version was tested on a VMSAlpha7.2 system using DECC6.0, but
+probably also works for other versions.
+
+At the moment only the libraries LIBMESGL.EXE/LIBMESGL.OLB,
+LIBMESAGLU.EXE/LIBMESAGLU.OLB and LIBGLUT.EXE/LIBGLUT.OLB and the demos of the
+directory [.DEMOS] can be build.
+However, feel free to create the missing "decrip.mms-files" in the other
+directories.
+
+ The make files were tested
+using the DIGITAL make utility called MMS.  There is also a public domain
+clone available (MMK) and I  think, but it is not tested, that this
+utility will give (hardly) any problem.
+
+To make everything just type MMS (or MMK) in the main directory of
+mesagl.  For MMS the deafult makefile is called descrip.mms, and
+that is what I have called it.  I included alse some config files,
+all having mms somewhere in the name which all the makefiles need
+(just as your unix makefiles).
+
+On Alpha platforms at default a sharable images for the libraries are created.
+To get a static library make it by typing MMS/MACRO=(NOSHARE=1).
+On VAX platforms only static libraries can be build.
+
+
+You may want to compile Mesa to use IEEE floating point arithmetic, instead
+of VAX floating point by specifying the /float=IEEE flag to the compiler.

+
+Quick Start
+----- -----
+
+Unzip both ZIP files (MesaLib and MesaDemos) into the same directory.
+The libs and demos build separately, so if you do not care about the
+demos, you do not have to unzip that zip file.  But if you do, it does
+need to be unzipped into the same directory as the lib zip file
+because the demos depend on the libs.
+
+The Windows build system uses Microsoft Visual Studio.  Project files
+for a specific version of Visual Studio are in their own directory in
+the top-level "windows" directory.  For example, Visual Studio 6 files
+are in windows/VC6.  If a directory does not exist for your version of
+Visual Studio, you can try importing the project files from an earlier
+version of Visual Studio.  At this time, project files exist for
+Version 6 and Version 7.  The code has been built with a beta version
+of Version 8 and it runs on 64-bit Windows.  If you want to try this,
+start by importing the VC7 files and create the 64-bit targets in the
+configuration manager.
+
+The project files to build the core Mesa library, Windows Mesa
+drivers, OSMesa, and GLU are in the mesa directory.  The project files
+to build GLUT and some demo programs are in the progs directory.
+
+Makefiles are no longer shipped or supported, but can be generated
+from the projects using Visual Studio.
+
+
+Windows Drivers
+------- -------
+
+At this time, only the GDI driver is known to work, as it has been
+ported and rewritten to the latest Mesa DD interfaces.  Source code
+also exists in the tree for other drivers in src/mesa/drivers/windows,
+but the status of this code is unknown.
+
+The GDI driver operates basically by writing pixel spans into a DIB
+section and then blitting the DIB to the window.  The driver was
+recently cleaned up and rewitten and so may have bugs or may be
+missing some functionality.  The older versions of the CVS source may
+be useful in figuring out any problems, or report them to me.
+
+To build Mesa with the GDI driver, build the mesa, gdi, and glu
+projects in the Visual Studio workspace found at
+
+	windows/VC6/mesa/mesa.dsw
+or
+	windows/VC7/mesa/mesa.sln
+
+The osmesa DLL can also be built with the osmesa project.
+
+The build system creates a lib top-level directory and copies
+resulting LIB and DLL files to this lib directory.  The files are:
+
+	OPENGL32.LIB, GLU32.LIB, OSMESA32.LIB
+	OPENGL32.DLL, GLU32.DLL, OSMESA32.DLL
+
+If the MesaDemos ZIP file was extracted, the DLL files are also copied
+to the demos directory.  This facilitates running the demos as described
+below.
+
+
+GLUT and Demos
+---- --- -----
+
+A Visual Studio workspace can be found at 
+
+	windows/VC6/progs/progs.dsw
+or
+	windows/VC7/progs/progs.sln
+
+It can be used to build GLUT and a few demos.  The GLUT lib and DLL
+are copied to the top-level lib directory, along with the Mesa libs.
+
+The demo build system expects to find the LIB files in the top level
+lib directory, so you must build the Mesa libs first.  The demo
+executables are placed in the demos directory, because some of them
+rely on data files found there.  Also, the Mesa lib DLL's were copied
+there by the Mesa lib build process.  Therefore, you should be able to
+simply run the demo executables from the demo directory.
+
+If you want to run the demos from the Visual Studio, you may have to
+change the startup directory and explicitly state where the executables are.
+
+
+Build System Notes
+----- ------ -----
+
+VC6
+---
+
+Visual Studio 6 does not recognize files with the .cc extension as C++
+language files, without a lot of unnatural tweaking.  So, the VC6
+build process uses custom build steps to compile these files in the
+GLU library.
+
+
+VC7
+---
+
+The above-mentioned .cc problem does not exist in this version.
+
+
+General
+-------
+
+After building, you can copy the above DLL files to a place in your
+PATH such as $SystemRoot/SYSTEM32.  If you don't like putting things
+in a system directory, place them in the same directory as the
+executable(s).  Be careful about accidentially overwriting files of
+the same name in the SYSTEM32 directory.
+
+The DLL files are built so that the external entry points use the
+stdcall calling convention.
+
+Static LIB files are not built.  The LIB files that are built with are
+the linker import files associated with the DLL files.
+
+The si-glu sources are used to build the GLU libs.  This was done
+mainly to get the better tessellator code.
+
+To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
+to the project settings.  You will also need to edit src/mesa.def to
+change all the gl* symbols to mgl*.  Because this is easy to do with a
+global replace operation in a text editor, no additional mangled
+version of mesa.def is maintained or shipped.
+
+If you have a Windows-related build problem or question, it is
+probably better to direct it to me (kschultz@users.sourceforge.net),
+rather than directly to the other Mesa developers.  I will help you as
+much as I can.  I also monitor the Mesa mailing lists and will answer
+questions in this area there as well.

+2. Add the following line to your torVars.bat:
+set MESA_BASE=C:\Mesa
+
+OR copy the new torVars.bat in your bin path:
+c:/Mesa/src/ugl/tornado/torVars.sample -> 
+/mnt/nt/Tornado/host/x86-win32/bin/torVars (for example)
+
+3. In a command prompt:
+$ torVars
+$ cd c:\Mesa
+$ make -f Makefile.ugl CPU=PENTIUM
+
+Take a long while...
+
+5. Include all the files from ugldemos folder to build some downloadable
+   application modules
+
+4. Download UGL/Mesa object files on target
+
+For example via the WindShell:
+ld < c:\Tornado\target\lib\objMesaGL.o
+ld < c:\Tornado\target\lib\objMesaUGL.o
+ld < c:\Tornado\target\lib\objMesaGLU.o
+ld < c:\Tornado\target\lib\objGLUTshapes.o
+ld < c:\Tornado\target\lib\objMesaOS.o
+
+You can put the previous lines in a file and use:
+< filename
+
+6. Download the application modules.
+
+7. In WindShell, run:
+-> uglalldemos
+
+During the show some messages will appear, it provides some useful
+information on key management.
+
+
+Coding
+------
+
+Sample Usage:
+
+In addition to the usual ugl calls to initialize UGL, (may be find an
+input driver), you must do the following to use the UGL/Mesa interface:
+
+1. Call uglMesaCreateContext() to create a UGL/Mesa rendering context,
+   given the display format.
+
+2. Call uglMesaMakeCurrent() to bind the UGL/Mesa buffers to an
+   UGL/Mesa Context and to make the context the current one.
+
+3. Make gl* calls to render your graphics.
+
+4. Use uglMesaSwapBuffers() when double buffering to swap front/back buffers.
+
+5. Before the UGL is destroyed, call MesaDestroyContext().
+
+6. Before exiting, call if required uglEventQDestroy and then
+   uglDeinitialize();
+
+Limitations
+-----------
+
+I found the following limitations in my driver :
+ - Color Indexed management is only in 8 bits
+ - It's possible to mix UGL/OpenGL application with a software
+   double buffer

+                          Mesa Unix/X11 Information
+
+
+
+Installation
+============
+
+There are two ways to compile Mesa on Unix/X11 systems:
+
+1. The old way:
+    First type 'make' alone to see the list of system
+    configurations currently supported.  If you see your configuration on the
+    list, type 'make <config>'.  Most popular Unix/X workstations are currently
+    supported.
+
+    If your system configuration is not listed by 'make', you'll have to modify
+    the top-level Makefile and Make-config files.  There are instructions in
+    each file.
+
+    When finished, the Mesa libraries will be in the Mesa-x.y/lib/ directory.
+
+
+2. The new way:
+    Type './configure' and then 'make'.  This uses GNU autoconfig.
+    Run 'make check' to build the demos.
+    See docs/INSTALL for more details.
+    When finished, the Mesa libraries will be in the Mesa-x.y/src/.libs/,
+    Mesa-x.y/si-glu/.libs, etc directories.
+
+
+Notes on assembly language optimizations:
+
+   When using the old-style Makefiles, you can specify a configuration
+   that uses X86 assembly language optimizations (linux-3dnow for example).
+
+   The detection of MMX, 3DNow!, PIII/SSE, etc capability is done at
+   runtime.  That means you can compile Mesa for 3DNow! optimizations
+   even if you don't have an AMD CPU.
+
+   However, your Linux binutils and assembler must understand the
+   special instructions in order to compile them.  If you have
+   compilation problems, try upgrading your binutils.
+
+
+Header and library files:
+   After you've compiled Mesa and tried the demos I recommend the following
+   procedure for "installing" Mesa.
+
+   Copy the Mesa include/GL directory to /usr/local/include:
+	cp -r include/GL /usr/local/include
+
+   Copy the Mesa library files to /usr/local/lib:
+	cp lib/* /usr/local/lib
+
+	(actually, use "cp -d" on Linux to preserve symbolic links)
+
+
+Xt/Motif widgets:
+   If you want to use Mesa or OpenGL in your Xt/Motif program you can build
+   the widgets found in either the widgets-mesa or widgets-sgi directories.
+   The former were written for Mesa and the later are the original SGI
+   widgets.  Look in those directories for more information.
+
+
+Notes:
+   HP users:  a Mesa user reports that the HP-UX 10.01 C compiler has
+   a bug which effects glReadPixels.  A patch for the compiler (PHSS_5743) is
+   available.  Otherwise be sure your compiler is version 10.13 or later.
+
+   QNX users:  if you have problems running the demos try setting the
+   stack size to 200K or larger with -N200K, for example.
+
+   SunOS 5.x users:  The X shared memory extension may not work
+   correctly.  If Mesa prints an error message to the effect of "Shared memory
+   error" then you'll have to append the following three lines to the end of
+   your /etc/system file then reboot:
+      set shmsys:shminfo_shmmax = 0x2000000
+      set shmsys:shminfo_shmmni = 0x1000
+      set shmsys:shminfo_shmseg = 0x100
+
+
+
+Using the library
+=================
+
+Configuration options:
+   The file src/mesa/main/config.h has many parameters which you can adjust
+   such as maximum number of lights, clipping planes, maximum texture size,
+   etc.  In particular, you may want to change DEPTH_BITS from 16 to 32
+   if a 16-bit depth buffer isn't precise enough for your application.
+
+
+Shared libraries:
+   If you compile shared libraries you may have to set an environment
+   variable to specify where the Mesa libraries are located.  On Linux and
+   Sun systems for example, set the LD_LIBRARY_PATH variable to include
+   /your-dir/Mesa-2.6/lib.   Otherwise, when you try to run a demo it
+   may fail with a message saying that one or more libraries couldn't be
+   found.
+
+
+Remote display of OpenGL/GLX programs:
+   As of version 1.2.3, Mesa's header files use the same GLenum and GLUenum
+   values as SGI's (and most/all other vendor's) OpenGL headers.  This means
+   you can freely mix object files compiled with OpenGL or Mesa headers.
+   In fact, on systems with dynamic runtime linkers it's possible to dynam-
+   ically link with Mesa or OpenGL shared libraries at runtime, without
+   recompiling or relinking anything!
+
+   Using IRIX 5.x as an example, you can run SGI's OpenGL demos with the
+   Mesa shared libraries as follows.  Let's assume you're installing Mesa
+   in /usr/local/Mesa and using the C-shell:
+       % cd /usr/local/Mesa
+       % make irix5-dso
+       % setenv _RLD_LIST "/usr/local/Mesa/lib/libGL.so:DEFAULT"
+       % /usr/demos/bin/ideas_ogl      // this is a test
+
+   You can now run OpenGL executables on almost any X display!  There may
+   be some problems from the fact that Mesa supports many X visual types
+   that an OpenGL client may not expect (grayscale for example).  In this
+   case the application may abort, print error messages, or just behave
+   strangely.  You may have to experiment with the MESA_RGB_VISUAL envi-
+   ronment variable.
+
+
+Xt/Motif Widgets:
+   Two versions of the Xt/Motif OpenGL drawing area widgets are included:
+
+      widgets-sgi/	SGI's stock widgets
+      widgets-mesa/	Mesa-tuned widgets
+
+   Look in those directories for details
+
+
+Togl:
+   Togl is an OpenGL/Mesa widget for Tcl/Tk.
+   See http://togl.sourceforge.net for more information.
+
+
+
+X Display Modes:
+   Mesa supports RGB(A) rendering into almost any X visual type and depth.
+
+   The glXChooseVisual function tries its best to pick an appropriate visual
+   for the given attribute list.  However, if this doesn't suit your needs
+   you can force Mesa to use any X visual you want (any supported by your
+   X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL
+   environment variables.  When an RGB visual is requested, glXChooseVisual
+   will first look if the MESA_RGB_VISUAL variable is defined.  If so, it
+   will try to use the specified visual.  Similarly, when a color index
+   visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL
+   variable.
+
+   The format of accepted values is:  <visual-class> <depth>
+   Here are some examples:
+
+   using the C-shell:
+	% setenv MESA_RGB_VISUAL "TrueColor 8"		// 8-bit TrueColor
+	% setenv MESA_CI_VISUAL "PseudoColor 12"	// 12-bit PseudoColor
+	% setenv MESA_RGB_VISUAL "PseudoColor 8"	// 8-bit PseudoColor
+
+   using the KornShell:
+	$ export MESA_RGB_VISUAL="TrueColor 8"
+	$ export MESA_CI_VISUAL="PseudoColor 12"
+	$ export MESA_RGB_VISUAL="PseudoColor 8"
+
+
+Double buffering:
+   Mesa can use either an X Pixmap or XImage as the backbuffer when in
+   double buffer mode.  Using GLX, the default is to use an XImage.  The
+   MESA_BACK_BUFFER environment variable can override this.  The valid
+   values for MESA_BACK_BUFFER are:  Pixmap and XImage (only the first
+   letter is checked, case doesn't matter).
+
+   A pixmap is faster when drawing simple lines and polygons while an
+   XImage is faster when Mesa has to do pixel-by-pixel rendering.  If you
+   need depth buffering the XImage will almost surely be faster.  Exper-
+   iment with the MESA_BACK_BUFFER variable to see which is faster for
+   your application.  
+
+
+Colormaps:
+   When using Mesa directly or with GLX, it's up to the application writer
+   to create a window with an appropriate colormap.  The aux, tk, and GLUT
+   toolkits try to minimize colormap "flashing" by sharing colormaps when
+   possible.  Specifically, if the visual and depth of the window matches
+   that of the root window, the root window's colormap will be shared by
+   the Mesa window.  Otherwise, a new, private colormap will be allocated.
+
+   When sharing the root colormap, Mesa may be unable to allocate the colors
+   it needs, resulting in poor color quality.  This can happen when a
+   large number of colorcells in the root colormap are already allocated.
+   To prevent colormap sharing in aux, tk and GLUT, define the environment
+   variable MESA_PRIVATE_CMAP.  The value isn't significant.
+
+
+Gamma correction:
+   To compensate for the nonlinear relationship between pixel values
+   and displayed intensities, there is a gamma correction feature in
+   Mesa.  Some systems, such as Silicon Graphics, support gamma
+   correction in hardware (man gamma) so you won't need to use Mesa's
+   gamma facility.  Other systems, however, may need gamma adjustment
+   to produce images which look correct.  If in the past you thought
+   Mesa's images were too dim, read on.
+
+   Gamma correction is controlled with the MESA_GAMMA environment
+   variable.  Its value is of the form "Gr Gg Gb" or just "G" where
+   Gr is the red gamma value, Gg is the green gamma value, Gb is the
+   blue gamma value and G is one gamma value to use for all three
+   channels.  Each value is a positive real number typically in the
+   range 1.0 to 2.5.  The defaults are all 1.0, effectively disabling
+   gamma correction.  Examples using csh:
+
+	% setenv MESA_GAMMA "2.3 2.2 2.4"	// separate R,G,B values
+	% setenv MESA_GAMMA "2.0"		// same gamma for R,G,B
+
+   The demos/gamma.c program may help you to determine reasonable gamma
+   value for your display.  With correct gamma values, the color intensities
+   displayed in the top row (drawn by dithering) should nearly match those
+   in the bottom row (drawn as grays).
+
+   Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well
+   on HP displays using the HP-ColorRecovery technology.
+
+   Mesa implements gamma correction with a lookup table which translates
+   a "linear" pixel value to a gamma-corrected pixel value.  There is a
+   small performance penalty.  Gamma correction only works in RGB mode.
+   Also be aware that pixel values read back from the frame buffer will
+   not be "un-corrected" so glReadPixels may not return the same data
+   drawn with glDrawPixels.
+
+   For more information about gamma correction see:
+   http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html
+
+
+Overlay Planes
+
+   Overlay planes in the frame buffer are supported by Mesa but require
+   hardware and X server support.  To determine if your X server has
+   overlay support you can test for the SERVER_OVERLAY_VISUALS property:
+
+	xprop -root | grep SERVER_OVERLAY_VISUALS
+
+
+HPCR glClear(GL_COLOR_BUFFER_BIT) dithering
+
+   If you set the MESA_HPCR_CLEAR environment variable then dithering
+   will be used when clearing the color buffer.  This is only applicable
+   to HP systems with the HPCR (Color Recovery) system.
+
+
+Extensions
+==========
+   There are three Mesa-specific GLX extensions at this time.
+
+   GLX_MESA_pixmap_colormap 
+
+      This extension adds the GLX function:
+
+         GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
+                                           Pixmap pixmap, Colormap cmap )
+
+      It is an alternative to the standard glXCreateGLXPixmap() function.
+      Since Mesa supports RGB rendering into any X visual, not just True-
+      Color or DirectColor, Mesa needs colormap information to convert RGB
+      values into pixel values.  An X window carries this information but a
+      pixmap does not.  This function associates a colormap to a GLX pixmap.
+      See the xdemos/glxpixmap.c file for an example of how to use this
+      extension.
+
+   GLX_MESA_release_buffers
+
+      Mesa associates a set of ancillary (depth, accumulation, stencil and
+      alpha) buffers with each X window it draws into.  These ancillary
+      buffers are allocated for each X window the first time the X window
+      is passed to glXMakeCurrent().  Mesa, however, can't detect when an
+      X window has been destroyed in order to free the ancillary buffers.
+
+      The best it can do is to check for recently destroyed windows whenever
+      the client calls the glXCreateContext() or glXDestroyContext()
+      functions.  This may not be sufficient in all situations though.
+
+      The GLX_MESA_release_buffers extension allows a client to explicitly
+      deallocate the ancillary buffers by calling glxReleaseBuffersMESA()
+      just before an X window is destroyed.  For example:
+
+         #ifdef GLX_MESA_release_buffers
+            glXReleaseBuffersMESA( dpy, window );
+         #endif
+         XDestroyWindow( dpy, window );
+
+      This extension is new in Mesa 2.0.
+
+   GLX_MESA_copy_sub_buffer
+
+      This extension adds the glXCopySubBufferMESA() function.  It works
+      like glXSwapBuffers() but only copies a sub-region of the window
+      instead of the whole window.
+
+      This extension is new in Mesa version 2.6
+
+
+
+Summary of X-related environment variables:
+   MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only)
+   MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only)
+   MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only)
+   MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only)
+   MESA_GAMMA - gamma correction coefficients (X only)

+
+                             PLEASE READ!!!!
+
+
+New copyright
+-------------
+
+Mesa 3.1 will be distributed under an XFree86-style copyright instead
+of the GNU LGPL.
+
+
+New directories
+---------------
+
+All documentation files are now in the docs/ directory.
+All shell scripts are now in the bin/ directory.
+
+
+New library names
+-----------------
+
+Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a)
+and the GLU library was named libMesaGLU.so (or libMesaGLU.a).
+
+Now, the main library is named libGL.so (or libGL.a) and the GLU library
+is named libGLU.so (or libGLU.a).
+
+The change allows Mesa to be more easily substituted for OpenGL.
+Specifically, the linker/loader on some Unix-like systems won't
+allow libMesaGL.so to be used instead of libGL.so if the application
+was linked with the former.
+
+Warning: if you have another OpenGL implementation installed on your
+system (i.e. you have another OpenGL libGL.so) you'll have to be
+carefull about which library (OpenGL or Mesa) you link against.  Be
+aware of -L linker flags and the value of the LD_LIBRARY_PATH environment
+variable.
+
+
+New library versioning
+----------------------
+
+Previously, the Mesa GL library was named libMesaGL.so.3.0
+To better support Linux/OpenGL standards, the Mesa GL library is now
+named libGL.so.1.2.030100  This indicates version 1.2 of the OpenGL spec
+and Mesa implementation 3.1.0
+
+In the long term this will allow better interoperability with other
+OpenGL implementations, especially on Linux.  In the short term,
+OpenGL apps may have to be relinked to use the new library naming.
+
+
+
+New makefiles
+-------------
+
+The old Makefiles found in the various directories have been renamed
+to Makefile.X11 in order to prevent filename collisions with autoconfig-
+generated Makefiles.
+
+The top-level Makefile simply includes Makefile.X11
+If your top-level Makefile get's overwritten/destroyed you can restore
+it by copying Makefile.X11 to Makefile
+
+
+New extensions
+--------------
+
+GL_EXT_stencil_wrap
+	Implements two new stencil operations: GL_INCR_WRAP_EXT and
+	GL_DECR_WRAP_EXT which allow stencil increment and decrement
+	without clamping.
+
+GL_INGR_blend_func_separate
+	Allows specification of blend factors for RGB and Alpha independently.
+	(INGR = Intergraph)
+
+GL_ARB_multitexture
+	Multiple simultaneous textures.  (ARB = Architecture Review Board)
+
+GL_NV_texgen_reflection
+	nVidia texgen extension for better reflection mapping.
+
+GL_PGI_misc_hints
+	Assorted transformation hints.
+
+GL_EXT_compiled_vertex_array
+	Compiled vertex arrays.
+
+GL_EXT_clip_volume_hint
+	Allows one to disable clip volume (frustum) testing.
+
+
+
+Extensions removed
+------------------
+
+GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture
+
+
+
+Config file
+-----------
+
+By default, /etc/mesa.conf will be read when Mesa starts.  This
+file controls default hints, enable/disable of extensions, and
+more.  See the CONFIG file for documentation.
+
+
+
+Optimizations
+-------------
+
+Keith Whitwell has contributed significant optimizations to Mesa's
+vertex transformation code.  Basically, the whole transformation
+stage of Mesa has been rewritten.
+
+It's impossible to give a speedup factor.  You'll just have to
+try your app and see how it performs.
+
+
+
+Device Driver changes
+---------------------
+
+A bunch of new device driver functions have been added.  See src/dd.h
+Keith Harrison contributed many of them.  I've been planning on adding
+a bunch of functions like these to make writing hardware drivers easier.
+More such function will probably be added in the near future.
+
+
+
+Miscellaneous
+-------------
+
+util/glstate.c has some handy functions for debugging.  Basically, it
+offers a simple function for printing GL state variables.  It's not
+finished yet.  There's a LOT more GLenum records to be added (see the
+code).  Anyone want to help?
+

+See the VERSIONS file for the exact list.
+
+
+
+GLU Polygon Tessellator
+-----------------------
+
+The GLU tessellator has been reverted back to the version included
+with Mesa 3.0 since it's more stable.  The Mesa 3.1/3.2 tessellator
+implemented the GLU 1.3 specification but suffered from a number of
+bugs.
+
+Mesa implements GLU 1.1.
+
+Ideally, people should use the GLU 1.3 library included in SGI's
+OpenGL Sample Implementation (SI) available from 
+http://oss.sgi.com/projects/ogl-sample/
+People are working to make easy-to-install Linux RPMs of the
+GLU library.

+
+                             July 21, 2000
+
+                             PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.2.1) designate stable releases.
+
+Mesa 3.3 has a undergone many internal changes since version 3.2
+and features a lot of new extensions.  3.3 is expected to be pretty
+stable, but perhaps not as stable as 3.2 which has been used by
+thousands of users over the past months.
+
+Everyone is encouraged to try Mesa 3.3.  Bugs should be reported to
+the Mesa bug database on www.sourceforge.net.
+
+
+
+Header file / GLenum changes
+----------------------------
+
+The gl.h and glu.h headers now use #defines to define all GL_* tokens
+instead of C-language enums.  This change improves Mesa/OpenGL
+interoperability.
+
+
+
+New API dispatch code
+---------------------
+
+The core Mesa gl* functions are now implemented with a new dispatch
+(jump table) which will allow simultaneous direct/indirect rendering.
+
+The code is found in the glapi*.[ch] files.
+
+Of interest:  the actual "glFooBar" functions are generated with
+templatized code defined in glapitemp.h and included by glapi.c
+The glapitemp.h template should be reusable for all sorts of OpenGL
+projects.
+
+The new dispatch code has also optimized with x86 assembly code.
+This optimization eliminates copying the function arguments during
+dispatch.
+
+
+
+New thread support
+------------------
+
+Thread support in Mesa has been rewritten.  The glthread.[ch] files
+replace mthreads.[ch].  Thread safety is always enabled (on platforms
+which support threads, that is).  There is virtually no performance
+penalty for typical single-thread applications.  See the glapi.c
+file for details.
+
+The Xlib driver (XMesa) is now thread-safe as well.  Be sure to
+call XInitThreads() in your app first.  See the xdemos/glthreads.c
+demo for an example.
+
+
+
+Make configuration changes
+--------------------------
+
+If you use the old-style (non GNU automake) method to build Mesa note
+that several of the configuration names have changed:
+
+   Old name        New name
+   -------------   ----------------
+   linux-elf       linux
+   linux           linux-static
+   linux-386-elf   linux-386
+   linux-386       linux-386-static
+   etc.
+
+
+
+New extensions
+--------------
+
+GL_ARB_transpose_matrix
+	Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
+        functions.
+
+GL_ARB_texture_cube_map
+	For cube-based reflection mapping.
+
+GL_EXT_texture_add_env
+	Adds GL_ADD texture environment mode.
+	See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt
+
+GL_EXT_texture_lod_bias
+	Allows mipmapped texture blurring and sharpening.
+
+GLX_EXT_visual_rating extension
+	This extension has no effect in stand-alone Mesa (used for DRI).
+
+GL_HP_occlusion_test
+	Used for bounding box occlusion testing (see demos/occlude.c).
+
+GL_SGIX_pixel_texture / GL_SGIS_pixel_texture
+	Lets glDraw/CopyPixels draw a texture coordinate image.
+
+GL_SGI_color_matrix
+	Adds a color matrix and another set of scale and bias parameters
+	to the glDraw/CopyPixels paths.
+
+GL_SGI_color_table
+	Adds additional color tables to the glDraw/Read/CopyPixels paths.
+
+GL_EXT_histogram
+	Compute histograms for glDraw/Read/CopyPixels.
+
+GL_EXT_blend_func_separate
+	This is the same as GL_INGR_blend_func_separate.
+
+GL_ARB_texture_cube_mapping
+	6-face cube mapping, nicer than sphere mapping
+
+GL_EXT_texture_env_combine
+	For advanced texture environment effects.
+
+
+Documentation for all these functions can be found at
+http://oss.sgi.com/projects/ogl-sample/registry/
+
+
+
+GLX_SGI_make_current_read functionality
+---------------------------------------
+
+The functionality of this extension is needed for GLX 1.3 (and required
+for the Linux/OpenGL standards base).
+
+Implementing this function required a **DEVICE DRIVER CHANGE**.
+The old SetBuffer() function has been replaced by SetReadBuffer() and
+SetDrawBuffer().  All device drivers will have to be updated because
+of this change.
+
+The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa.
+The xdemos/wincopy.c program demonstrates it.
+
+
+
+Image-related code changes
+--------------------------
+
+The imaging path code used by glDrawPixels, glTexImage[123]D,
+glTexSubImage[123], etc has been rewritten.  It's now faster,
+uses less memory and has several bug fixes.  This work was
+actually started in Mesa 3.1 with the glTexImage paths but has now
+been carried over to glDrawPixels as well.
+
+
+
+Device driver interface changes
+-------------------------------
+
+Added new functions for hardware stencil buffer support:
+   WriteStencilSpan
+   ReadStencilSpan
+   WriteStencilPixels
+   ReadStencilPixels
+
+
+Removed old depth buffer functions:
+   AllocDepthBuffer
+   DepthTestSpan
+   DepthTestPixels
+   ReadDepthSpanFloat
+   ReadDepthSpanInt
+
+
+Added new depth buffer functions:
+   WriteDepthSpan
+   ReadDepthSpan
+   WriteDepthPixels
+   ReadDepthPixels
+
+   These functions always read/write 32-bit GLuints.  This will allow
+   drivers to have anywhere from 0 to 32-bit Z buffers without
+   recompiling for 16 vs 32 bits as was previously needed.
+
+
+New texture image functions
+   The entire interface for texture image specification has been updated.
+   With the new functions, it's optional for Mesa to keep an internal copy
+   of all textures.  Texture download should be a lot faster when the extra
+   copy isn't made.
+
+Misc changes
+   TexEnv now takes a target argument
+   Removed UseGlobalTexturePalette (use Enable function instead)
+
+
+Also added
+   ReadPixels
+   CopyPixels
+
+
+The SetBufffer function has been replaced by SetDrawBuffer and
+SetReadBuffer functions.  This lets core Mesa independently
+specify which buffer is to be used for reading and which for
+drawing.
+
+The Clear function's mask parameter has changed.  Instead of
+mask being the flags specified by the user to glClear, the
+mask is now a bitmask of the DD_*_BIT flags in dd.h.  Now
+multiple color buffers can be specified for clearing (ala
+glDrawBuffers).  The driver's Clear function must also
+check the glColorMask glIndexMask, and glStencilMask settings
+and do the right thing.  See the X/Mesa, OS/Mesa, or FX/Mesa
+drivers for examples.
+
+
+The depth buffer changes shouldn't be hard to make for existing
+drivers.  In fact, it should simply the code.  Be careful with
+the depthBits value passed to gl_create_context().  1 is a bad
+value!  It should normally be 0, 16, 24, or 32.
+
+
+gl_create_framebuffer() takes new arguments which explicitly tell
+core Mesa which ancillary buffers (depth, stencil, accum, alpha)
+should be implemented in software.  Mesa hardware drivers should
+carefully set these flags depending on which buffers are in the
+graphics card.
+
+
+
+Internal constants
+------------------
+
+Point and line size range and granularity limits are now stored
+in the gl_constants struct, which is the Const member of GLcontext.
+The limits are initialized from values in config.h but may be
+overridden by device drivers to reflect the limits of that driver's
+hardware.
+
+Also added constants for NumAuxBuffers and SubPixelBits.
+
+
+
+OpenGL Conformance
+------------------
+
+Mesa now passes all the OpenGL 1.1 conformance tests, except for
+antialiased lines.  AA lines fail on some, but not all, the tests.
+In order to fix the remaining failures, a new AA line algorithm will
+be needed (which computes coverage values for end-point fragments).
+This will be done for Mesa 3.5/3.6.
+
+
+
+OpenGL 1.2 GL_ARB_imaging subset
+--------------------------------
+
+Mesa 3.3 implements all the features of GL_ARB_imaging except for
+image convolution.  This will (hopefully) be done for Mesa 3.5/3.6.
+
+

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.5) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+The biggest change in Mesa 3.5 is a complete overhaul of the source
+code in order to make it more modular.  This was driven by the DRI
+hardware drivers.  It simplifies the DRI drivers and opens the door
+to hardware transform/clip/lighting (TCL).  Keith Whitwell can take
+the credit for that.
+
+
+
+Driver Support
+--------------
+
+The device driver interface in Mesa 3.5 has changed a lot since Mesa 3.4
+Not all of the older Mesa drivers have been updated.  Here's the status:
+
+Driver			Status
+----------------------	-----------
+XMesa (Xlib)		updated
+OSMesa (off-screen)	updated
+FX (3dfx Voodoo1/2)	updated
+SVGA			updated
+GGI			not updated
+Windows/Win32		not updated
+DOS/DJGPP		not updated
+BeOS			not updated
+Allegro			not updated
+D3D			not updated
+DOS			not updated
+
+We're looking for volunteers to update the remaining drivers.  Please
+post to the Mesa3d-dev mailing list if you can help.
+
+
+
+GLU 1.3
+-------
+
+Mesa 3.5 includes the SGI Sample Implementation (SI) GLU library.
+This version of GLU supports the GLU 1.3 specification.  The old
+Mesa GLU library implemented the 1.1 specification.  The SI GLU
+library should work much better.
+
+You'll need a C++ compiler to compile the SI GLU library.  This may
+be a problem on some systems.
+
+
+
+New Extensions
+--------------
+
+GL_EXT_convolution
+	Adds image convolution to glRead/Copy/DrawPixels/TexImage.
+
+GL_ARB_imaging
+	This is the optional imaging subset of OpenGL 1.2.
+	It's the GL_EXT_convolution, GL_HP_convolution_border_modes,
+	GL_EXT_histogram, GL_EXT_color_table, GL_EXT_color_subtable
+	GL_EXT_blend_color, GL_EXT_blend_minmax, GL_EXT_blend_subtract
+	and GL_SGI_color_matrix extensions all rolled together.
+	This is supported in all software renderers but not in all
+	hardware drivers (3dfx for example).
+
+GL_ARB_texture_compression
+	This is supported in Mesa but only used by the 3dfx DRI drivers
+	for Voodoo4 and later.
+
+GL_ARB_texture_env_add
+	This is identical to GL_EXT_texture_env_add.
+
+GL_NV_blend_square
+	Adds extra blend source and dest factors which allow squaring
+	of color values.
+
+GL_EXT_fog_coord
+	Allows specification of a per-vertex fog coordinate instead of
+	having fog always computed from the eye distance.
+
+GL_EXT_secondary_color
+	Allows specifying the secondary (specular) color for each vertex
+	instead of getting it only from lighting in GL_SEPARATE_SPECULAR_COLOR
+	mode.
+
+GL_ARB_texture_env_combine
+	Basically the same as GL_EXT_texture_env_combine
+
+GL_ARB_texture_env_add extension
+	Texture addition mode.
+
+GL_ARB_texture_env_dot3 extension
+	Dot product texture environment.
+
+GL_ARB_texture_border_clamp
+	Adds GL_CLAMP_TO_BORDER_ARB texture wrap mode
+
+GL_SGIX_depth_texture, GL_SGIX_shadow and GL_SGIX_shadow_ambient
+	Implements a shadow casting algorithm based on depth map textures
+
+GL_SGIS_generate_mipmap
+	Automatically generate lower mipmap images whenever the base mipmap
+	image is changed with glTexImage, glCopyTexImage, etc.
+
+
+
+libOSMesa.so
+------------
+
+libOSMesa.so is a new library which contains the OSMesa interface for
+off-screen rendering.  Apps which need the OSMesa interface should link
+with both -lOSMesa and -lGL.  This change was made so that stand-alone
+Mesa works the same way as XFree86/DRI's libGL.
+
+
+
+Device Driver Changes / Core Mesa Changes
+-----------------------------------------
+
+The ctx->Driver.LogicOp() function has been removed.  It used to
+be called during state update in order to determine if the driver
+could do glLogicOp() operations, and if not, set the SWLogicOpEnabled
+flag.  Drivers should instead examine the LogicOp state themselves
+and choose specialized point, line, and triangle functions appropriately,
+or fall back to software rendering.  The Xlib driver was the only driver
+to use this function.  And since the Xlib driver no longer draws
+points, lines or triangles using Xlib, the LogicOp function isn't needed.
+
+The ctx->Driver.Dither() function has been removed.  Drivers should
+detect dither enable/disable via ctx->Driver.Enable() instead.
+
+The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions
+are now just called from glIndexMask and glColorMask like the other
+GL state-changing functions.  They are no longer called from inside
+gl_update_state().  Also, they now return void.  The change was made
+mostly for sake of uniformity.
+
+The NEW_DRVSTATE[0123] flags have been removed.  They weren't being used
+and are obsolete w.r.t. the way state updates are done in DRI drivers.
+
+
+Removed obsolete gl_create_visual() and gl_destroy_visual().
+
+Renamed functions (new namespace):
+
+old				new
+gl_create_framebuffer		_mesa_create_framebuffer
+gl_destroy_framebuffer		_mesa_destroy_framebuffer
+gl_create_context		_mesa_create_context
+gl_destroy_context		_mesa_destroy_context
+gl_context_initialize		_mesa_context_initialize
+gl_copy_context			_mesa_copy_context
+gl_make_current			_mesa_make_current
+gl_make_current2		_mesa_make_current2
+gl_get_current_context		_mesa_get_current_context
+gl_flush_vb			_mesa_flush_vb
+gl_warning			_mesa_warning
+gl_compile_error		_mesa_compile_error
+
+
+All the drivers have been updated, but not all of them have been
+tested since I can't test some platforms (DOS, Windows, Allegro, etc).
+
+
+X/Mesa Driver
+-------------
+
+The source files for the X/Mesa driver in src/X have been renamed.
+The xmesa[1234].c files are gone.  The new files are xm_api.c,
+xm_dd.c, xm_line.c, xm_span.c and xm_tri.c.
+
+
+
+Multitexture
+------------
+
+Eight texture units are now supported by default.
+
+
+
+OpenGL SI related changes
+-------------------------
+
+In an effort to make Mesa's internal interfaces more like the OpenGL
+SI interfaces, a number of changes have been made:
+
+1. Importing the SI's glcore.h file which defines a number of
+interface structures like __GLimports and __GLexports.
+
+2. Renamed "struct gl_context" to "struct __GLcontextRec".
+
+3. Added __glCoreCreateContext() and __glCoreNopDispatch() functions.
+
+4. The GLcontext member Visual is no longer a pointer.
+
+5. New file: imports.c to setup default import functions for Mesa.
+
+
+
+
+16-bit color channels
+---------------------
+
+There's experimental support for 16-bit color channels (64-bit pixels)
+in Mesa 3.5.  Only the OSMesa interface can be used for 16-bit rendering.
+Type "make linux-osmesa16" in the top-level directory to build the
+special libOSMesa16.so library.
+
+This hasn't been tested very thoroughly yet so please file bug reports
+if you have trouble.
+
+In the future I hope to implement support for 32-bit, floating point
+color channels.

+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+Mesa version 4.0 signifies two things:
+
+  1. A stabilization of the 3.5 development release
+  2. Implementation of the OpenGL 1.3 specification
+
+
+Note that the Mesa major version number is incremented with the OpenGL
+minor version number:
+
+   Mesa 1.x  ==  OpenGL 1.0
+   Mesa 2.x  ==  OpenGL 1.1
+   Mesa 3.x  ==  OpenGL 1.2
+   Mesa 4.x  ==  OpenGL 1.3
+
+
+
+New Features
+------------
+
+Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as
+extensions.  These extensions were simply promoted to standard features:
+
+   GL_ARB_multisample
+   GL_ARB_multitexture
+   GL_ARB_texture_border_clamp
+   GL_ARB_texture_compression
+   GL_ARB_texture_cube_map
+   GL_ARB_texture_env_add
+   GL_ARB_texture_env_combine
+   GL_ARB_texture_env_dot3
+   GL_ARB_transpose_matrix
+
+In Mesa 4.0 the functions defined by these extensions are now available
+without the "ARB" suffix.  For example, glLoadTransposeMatrixf() is now
+a standard API function.  The new functions in OpenGL 1.3 and Mesa 4.0 are:
+
+   glActiveTexture
+   glClientActiveTexture
+   glCompressedTexImage1D
+   glCompressedTexImage2D
+   glCompressedTexImage3D
+   glCompressedTexSubImage1D
+   glCompressedTexSubImage2D
+   glCompressedTexSubImage3D
+   glGetCompressedTexImage
+   glLoadTransposeMatrixd
+   glLoadTransposeMatrixf
+   glMultiTexCoord1d
+   glMultiTexCoord1dv
+   glMultiTexCoord1f
+   glMultiTexCoord1fv
+   glMultiTexCoord1i
+   glMultiTexCoord1iv
+   glMultiTexCoord1s
+   glMultiTexCoord1sv
+   glMultiTexCoord2d
+   glMultiTexCoord2dv
+   glMultiTexCoord2f
+   glMultiTexCoord2fv
+   glMultiTexCoord2i
+   glMultiTexCoord2iv
+   glMultiTexCoord2s
+   glMultiTexCoord2sv
+   glMultiTexCoord3d
+   glMultiTexCoord3dv
+   glMultiTexCoord3f
+   glMultiTexCoord3fv
+   glMultiTexCoord3i
+   glMultiTexCoord3iv
+   glMultiTexCoord3s
+   glMultiTexCoord3sv
+   glMultiTexCoord4d
+   glMultiTexCoord4dv
+   glMultiTexCoord4f
+   glMultiTexCoord4fv
+   glMultiTexCoord4i
+   glMultiTexCoord4iv
+   glMultiTexCoord4s
+   glMultiTexCoord4sv
+   glMultTransposeMatrixd
+   glMultTransposeMatrixf
+   glSampleCoverage
+   glSamplePass
+
+
+GLX 1.4 is the companion to OpenGL 1.3.  The only new features in GLX 1.4
+are support for multisampling and the GLX_ARB_get_proc_address extension.
+glXGetProcAddress() is the only new function in GLX 1.4.
+
+
+
+Multisample and Texture Compression
+-----------------------------------
+
+The OpenGL 1.3 specification allows the multisample and texture compression
+features to essentially be no-ops.  For example, if you query for multisample
+support you'll find none, but the API functions work.
+
+Similarly, texture compression is not implemented by any of the software
+drivers but you can specify a generic compressed texture format (like
+GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted.
+
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the
+device driver.  If the driver enables all the ARB extensions which are part
+of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3".  Otherwise,
+it'll return "1.2".
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time.  We rely on volunteers to maintain many of the drivers.
+Here's the current status of all included drivers:

+
+New Features in Mesa 4.1
+------------------------
+
+New extensions.  Docs at http://oss.sgi.com/projects/ogl-sample/registry/
+
+GL_NV_vertex_program
+
+    NVIDIA's vertex programming extension
+
+GL_NV_vertex_program1_1
+
+    A few features built on top of GL_NV_vertex_program
+
+GL_ARB_window_pos
+
+    This is the ARB-approved version of GL_MESA_window_pos
+
+GL_ARB_depth_texture
+
+    This is the ARB-approved version of GL_SGIX_depth_texture.
+    It allows depth (Z buffer) data to be stored in textures.
+    This is used by GL_ARB_shadow
+
+GL_ARB_shadow
+
+    Shadow mapping with depth textures.
+    This is the ARB-approved version of GL_SGIX_shadow.
+
+GL_ARB_shadow_ambient
+
+    Allows one to specify the luminance of shadowed pixels.
+    This is the ARB-approved version of GL_SGIX_shadow_ambient.
+
+GL_EXT_shadow_funcs
+
+    Extends the set of GL_ARB_shadow texture comparision functions to
+    include all eight of standard OpenGL dept-test functions.
+
+GL_ARB_point_parameters
+
+    This is basically the same as GL_EXT_point_parameters.
+
+GL_ARB_texture_env_crossbar
+
+    Allows any texture combine stage to reference any texture source unit.
+
+GL_NV_point_sprite
+
+    For rendering points as textured quads.  Useful for particle effects.
+
+GL_NV_texture_rectangle  (new in 4.0.4 actually)
+
+    Allows one to use textures with sizes that are not powers of two.
+    Note that mipmapping and several texture wrap modes are not allowed.
+
+GL_EXT_multi_draw_arrays
+
+    Allows arrays of vertex arrays to be rendered with one call.
+
+GL_EXT_stencil_two_side
+
+   Separate stencil modes for front and back-facing polygons.
+
+GLX_SGIX_fbconfig & GLX_SGIX_pbuffer
+
+   Off-screen rendering support.
+
+GL_ATI_texture_mirror_once
+
+   Adds two new texture wrap modes: GL_MIRROR_CLAMP_ATI and
+   GL_MIRROR_CLAMP_TO_EDGE_ATI.
+
+
+
+Device Driver Status
+--------------------
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time.  We rely on volunteers to maintain many of these drivers.
+Here's the current status of all included drivers:
+
+
+Driver			Status
+----------------------	---------------------
+XMesa (Xlib)		implements OpenGL 1.3
+OSMesa (off-screen)	implements OpenGL 1.3
+FX (3dfx Voodoo1/2)	implements OpenGL 1.3
+SVGA			implements OpenGL 1.3
+Wind River UGL		implements OpenGL 1.3
+Windows/Win32		implements OpenGL 1.3
+DOS/DJGPP		implements OpenGL 1.3
+GGI			implements OpenGL 1.3
+BeOS			needs updating (underway)
+Allegro			needs updating
+D3D			needs updating
+DOS			needs updating
+
+
+
+New features in GLUT
+--------------------
+
+1. Frames per second printing
+
+   GLUT now looks for an environment variable called "GLUT_FPS".  If it's
+   set, GLUT will print out a frames/second statistic to stderr when
+   glutSwapBuffers() is called.  By default, frames/second is computed
+   and displayed once every 5 seconds.  You can specify a different
+   interval (in milliseconds) when you set the env var.  For example
+   'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval
+   to one second.
+
+   NOTE: the demo or application must call the glutInit() function for
+   this to work.  Otherwise, the env var will be ignored.
+
+   Finally, this feature may not be reliable in multi-window programs.
+
+
+2. glutGetProcAddress() function
+
+   The new function:
+
+        void *glutGetProcAddress(const char *procName)
+
+   is a wrapper for glXGetProcAddressARB() and wglGetProcAddress().  It
+   lets you dynamically get the address of an OpenGL function at runtime.
+   The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the
+   GLUT version number from 3.7 since that's probably Mark Kilgard's role.
+
+   This function should probably also be able to return the address of
+   GLUT functions themselves, but it doesn't do that yet.
+
+
+
+XXX Things To Do Yet XXXX
+-------------------------
+
+isosurf with vertex program exhibits some missing triangles (probably
+when recycling the vertex buffer for long prims).
+
+
+
+Porting Info
+------------
+
+If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here
+are some things to change:
+
+1. ctx->Texture._ReallyEnabled is obsolete.
+
+   Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that
+   left room for only 6 units (6*5 < 32) in this field.
+   This field is being replaced by ctx->Texture._EnabledUnits which has one
+   bit per texture unit.  If the bit k of _EnabledUnits is set, that means
+   ctx->Texture.Unit[k]._ReallyEnabled is non-zero.  You'll have to look at
+   ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or
+   rect texture is enabled for unit k.
+
+   This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are
+   obsolete.
+
+   The tokens TEXTURE0_* have been replaced as well (since there's no
+   significance to the "0" part:
+
+   old token           new token
+   TEXTURE0_1D         TEXTURE_1D_BIT
+   TEXTURE0_2D         TEXTURE_2D_BIT
+   TEXTURE0_3D         TEXTURE_3D_BIT
+   TEXTURE0_CUBE       TEXTURE_CUBE_BIT
+   <none>              TEXTURE_RECT_BIT
+
+   These tokens are only used for the ctx->Texture.Unit[i].Enabled and
+   ctx->Texture.Unit[i]._ReallyEnabled fields.  Exactly 0 or 1 bits will
+   be set in _ReallyEnabled at any time!
+
+   Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?"
+   A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any
+      texure unit all at once (an unusual thing to do).
+      OpenGL defines priorities that basically say GL_TEXTURE_2D has
+      higher priority than GL_TEXTURE_1D, etc.  Also, just because a
+      texture target is enabled by the user doesn't mean we'll actually
+      use that texture!  If a texture object is incomplete (missing mip-
+      map levels, etc) it's as if texturing is disabled for that target.
+      The _ReallyEnabled field will have a bit set ONLY if the texture
+      target is enabled and complete.  This spares the driver writer from
+      examining a _lot_ of GL state to determine which texture target is
+      to be used.
+
+
+2. Tnl tokens changes
+
+   During the implementation of GL_NV_vertex_program some of the vertex
+   buffer code was changed.  Specifically, the VERT_* bits defined in
+   tnl/t_context.h have been renamed to better match the conventions of
+   GL_NV_vertex_program.  The old names are still present but obsolete.
+   Drivers should use the newer names.
+
+   For example:  VERT_RGBA is now VERT_BIT_COLOR0 and
+   VERT_SPEC_RGB is now VERT_BIT_COLOR1.
+
+
+
+3. Read/Draw Buffer changes
+
+   The business of setting the current read/draw buffers in Mesa 4.0.x
+   was complicated.  It's much simpler now in Mesa 4.1.
+
+   Here are the changes:
+
+   - Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask
+   - Removed ctx->Color.DriverDrawBuffer
+   - Removed ctx->Pixel.DriverReadBuffer
+   - Removed ctx->Color.MultiDrawBuffer
+   - Removed ctx->Driver.SetDrawBuffer()
+   - Removed swrast->Driver.SetReadBuffer().
+   - Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT
+     values to indicate the current draw buffers.
+   - Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading.
+     The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values.
+   - Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer().
+     These functions exactly correspond to glDrawBuffer and glReadBuffer calls.
+     Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and
+     leave ctx->Draw.ReadBuffer NULL.
+     DRI drivers should implement their own function for ctx->Driver.DrawBuffer
+     and use it to set the current hardware drawing buffer.  You'll probably
+     also want to check for GL_FRONT_AND_BACK mode and fall back to software.
+     Call _swrast_DrawBuffer() too, to update the swrast state.
+   - Added swrast->Driver.SetBuffer().
+     This function should be implemented by all device drivers that use swrast.
+     Mesa will call it to specify the buffer to use for span reading AND
+     writing and point/line/triangle rendering.
+     There should be no confusion between current read or draw buffer anymore.
+   - Added swrast->CurrentBuffer to indicate which color buffer to read/draw.
+     Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT.
+     This value is usually passed to swrast->Driver.SetBuffer().
+
+
+4. _mesa_create_context() changes.  This function now takes a pointer to
+   a __GLimports object.  The __GLimports structure contains function
+   pointers to system functions like fprintf(), malloc(), etc.
+   The _mesa_init_default_imports() function can be used to initialize
+   a __GLimports object.  Most device drivers (like the DRI drivers)
+   should use this.
+
+
+5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords"
+   has been replaced by "NdcPtr" to better match the OpenGL spec's
+   terminology.
+
+
+6. Since GL_EXT_stencil_two_side has been implemented, many of the
+   ctx->Stencil fields are now 2-element arrays.  For example,
+   "GLenum Ref" is now "GLenum Ref[2]"  The [0] elements are the front-face
+   values and the [1] elements are the back-face values.
+   ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for
+   the glStencilOp/Func/Mask() functions.
+   ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling
+   is enabled.
+
+
+7. Removed ctx->Polygon._OffsetAny.  Removed ctx->Polygon.OffsetMRD.
+
+
+8. GLfloat / GLchan changes:
+
+   - Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4].
+     ctx->Color.ClearColor is now GLfloat[4] too.
+   - Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan.
+   - ctx->Color.AlphaRef is now GLfloat.
+   - texObj->BorderColor is now GLfloat[4].  texObj->_BorderChan is GLchan[4].
+
+   This is part of an effort to remove all GLchan types from core Mesa so
+   that someday we can support 8, 16 and 32-bit color channels dynamically
+   at runtime, instead of at compile-time.
+
+
+9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced
+   by GLuint ctx->Transform.ClipPlanesEnabled.  The later is a bitfield.
+
+
+10. There's a new matrix_stack type in mtypes.h used for the Modelview,
+   Projection, Color and Texcoord matrix stacks.
+
+
+11. The ctx->Current.* fields have changed a lot.  Now, there's a
+   ctx->Current.Attrib[] array for all vertex attributes which matches
+   the NV vertex program conventions.
+

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Even-numbered versions (such as 5.0) designate stable releases.
+Odd-numbered versions (such as 4.1) designate new developmental releases.
+
+Mesa 5.0 is basically just a stabilization of Mesa 4.1.  To see a list of
+bug fixes, etc. see the VERSIONS file.
+
+
+
+New Features in Mesa 5.0
+------------------------
+
+Mesa 5.0 supports OpenGL 1.4.  Note Mesa's versioning convention:
+
+   OpenGL Version    Mesa Version
+   ------------------------------
+        1.0             1.x
+        1.1             2.x
+        1.2             3.x
+        1.3             4.x
+        1.4             5.x
+
+OpenGL 1.4 (and Mesa 5.0) incorporates the following OpenGL extensions as
+standard features:
+
+	GL_ARB_depth_texture
+	GL_ARB_shadow
+	GL_ARB_texture_env_crossbar
+	GL_ARB_texture_mirror_repeat
+	GL_ARB_window_pos
+	GL_EXT_blend_color
+	GL_EXT_blend_func_separate
+	GL_EXT_blend_logic_op
+	GL_EXT_blend_minmax
+	GL_EXT_blend_subtract
+	GL_EXT_fog_coord
+	GL_EXT_multi_draw_arrays
+	GL_EXT_point_parameters
+	GL_EXT_secondary_color
+	GL_EXT_stencil_wrap
+	GL_SGIS_generate_mipmap
+
+
+
+Device Driver Status
+--------------------
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time.  We rely on volunteers to maintain many of these drivers.
+Here's the current status of all included drivers:
+

+GGI			implements OpenGL 1.3
+DOS			implements OpenGL 1.4
+BeOS			needs updating (underway)

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Even-numbered versions (such as 5.0) designate stable releases.
+Odd-numbered versions (such as 5.1) designate new developmental releases.
+
+
+Bug fixes
+---------
+See the VERSIONS file for a list of bugs fixed in this release.
+
+
+
+New Features in Mesa 5.1
+------------------------
+
+GL_ARB_vertex_program / GL_ARB_fragment_program
+   Michal Krol and Karl Rasche implemented these extensions.  Thanks!
+   Be aware that there may be some rough edges and lurking bugs.
+
+GL_ATI_texture_env_combine3 extension
+   This adds a few new texture combine modes.
+   Contributed by Ian Romanick.
+
+GL_SGI_texture_color_table
+   Adds a color table lookup to the RGBA texture path.  There's a separate
+   color table for each texture unit.
+   Contributed by Eric Plante.
+
+GL_NV_fragment_program
+   NVIDIA's fragment-level programming feature.
+   Possible lurking bugs:
+     - the DDX and DDY commands aren't fully tested
+     - there may be bugs in the parser
+     - the TEX and TXP instructions both do perspective correction
+     - the pack/unpack instructions may not be correct
+
+GL_EXT_depth_bounds_test
+   This extension adds a scissor-like test for the Z axis.  It's used to
+   optimize stencil-volume shadow algorithms.
+
+GL_NV_light_max_exponent
+   Lifts the 128 limit for max light exponent.
+
+GL_EXT_texture_rectangle
+   Identical to GL_NV_texture_rectangle
+
+GL_ARB_occlusion_query
+   Useful for visibility-based culling.
+
+GL_ARB_texture_non_power_of_two
+   Removes the restriction that texture dimensions must be powers of two.
+
+GL_ARB_vertex_buffer_object
+   Allows server-side vertex arrays, optimized host/card data transfers, etc.
+
+GL_ARB_point_sprite
+   ARB-approved version of GL_NV_point_sprite.  Basically allows textures
+   to be applied to points.
+
+GL_IBM_multimode_draw_arrays
+   Allows multiple vertex arrays to be drawn with one call, including arrays
+   of different types of primitives.
+
+GL_SUN_multi_draw_arrays
+   An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4.
+
+Faster glDrawPixels / glCopyPixels in X11 driver
+   If your X screen is 32bpp, glDrawPixels to the front color buffer will
+   be accelerated (via XPutImage()) if the image format is GL_BGRA and the
+   type is GL_UNSIGNED_BYTE.  No raster operations, such as depth test,
+   blend, fog, etc. can be enabled.
+
+   If your X screen is 16bpp, glDrawPixels to the front color buffer will
+   be accelerated (via XPutImage()) if the image format is GL_RGB and the
+   type is GL_UNSIGNED_SHORT_5_6_5.  No raster operations, such as depth
+   test, blend, fog, etc. can be enabled.
+
+   glCopyPixels() calls for the front color buffer will be accelerated
+   (via XCopyArea()) if no raster operations, such as depth test, blend,
+   fog, pixel zoom, etc. are enabled.
+
+   The speed-up over typical software rendering is a factor of 10 for
+   glDrawPixels and 100 for glCopyPixels.
+
+
+With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object,
+GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports
+all the new features of OpenGL 1.5.  Mesa 6.0 (the next stable release)
+will advertise GL_VERSION = "1.5".
+ 
+
+
+Vertex/Fragment program debugger
+--------------------------------
+
+GL_MESA_program_debug is an experimental extension to support
+interactive debugging of vertex and fragment programs.  See the
+docs/MESA_program_debug.spec file for details.
+
+The bulk of the vertex/fragment program debugger is implemented
+outside of Mesa.  The GL_MESA_program_debug extension just has minimal
+hooks for stopping running programs and inspecting programs.
+
+The progs/tests/debugger.c (only in CVS) program is an example of how
+the extension can be used.  Presently, the debugger code and demo code
+is in the same file.  Eventually the debugger code should be moved
+into a reusable module.
+
+As it is now, the demo lets you set breakpoings in vertex/fragment
+programs, single step, and print intermediate register values.  It's
+basically just a proof of concept.
+
+
+
+Directory tree reorganization
+-----------------------------
+
+The directory structure for Mesa has been overhauled to improve its layout.
+All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
+in appropriate subdirectories.
+
+The Mesa source code and drivers has been reorganized under src/mesa/.
+
+All demonstration programs and tests are now in subdirectories under progs/.
+
+
+
+Build System Changes
+--------------------
+
+The GNU automake/autoconf support has been removed.  As it was, it seldom
+worked on anything but Linux.  The Mesa developers aren't big fans of
+automake/autoconf/libtool and didn't have the time to maintain it.
+If someone wants to contribute new automake/autoconf support (and is
+willing to maintain it), it may be re-incorporated into Mesa, subject
+to some requirements.
+
+The "old style" makefile system has been updated:
+   1. Make-config has been trimmed down to fewer, modern configurations.
+   2. Most of the bin/mklib.* scripts have been rolled into a new "mklib"
+      script that works on all sorts of systems.  There are probably some
+      bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5.
+      Improvements/contributes are greatly appreciated.
+   3. The Makefile.X11 files have been cleaned up in various ways
+
+
+

+-------------------
+
+The mmath.[ch] files are obsolete.  Their contents have been moved
+into the imports.[ch] and macros.[ch] files.

+	version.h		- defines the Mesa version info
+
+Other removed files:
+	swrast/s_histogram.[ch]   - moved into src/histogram.c
+
+
+
+Other Changes
+-------------
+
+The ctx->Driver.CreateTexture function has been removed - it wasn't used.
+
+New device driver hook functions:
+   NewTextureObject   - used to allocate struct gl_texture_objects
+   NewTextureImage    - used to allocate struct gl_texture_images
+
+New ctx->Texture._EnabledCoordUnits field:
+   With the addition of GL_NV_fragment_program we may need to interpolate
+   various sets of texture coordinates even when the corresponding texture
+   unit is not enabled.  That is, glEnable(GL_TEXTURE_xD) may never get
+   called but we still may have to interpolate texture coordinates across
+   triangles so that the fragment program will get them.
+   This new field indicates which sets of texture coordinates are needed.
+   If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the
+   same bit MUST be set in ctx->Texture._EnabledCoordUnits.
+
+The ctx->_TriangleCaps field is deprecated.
+   Instead of testing the DD_* bits in _TriangleCaps, you should instead
+   directly test the relevant state variables, or use one of the helper
+   functions like NEED_SECONDARY_COLOR() at the bottom of context.h
+   While testing _TriangleCaps bits was fast, it was kludgey, and setting
+   the bits in the first place could be error prone.
+
+New vertex processing code.
+   The code behind glBegin, glEnd, glVertex, glNormal, etc. has been
+   totally rewritten.  It's a cleaner implementation now and should use
+   less memory. (Keith)
+
+
+
+To Do
+-----
+Add screen-awareness to fakeglx.c

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 5.1) designate new developmental releases.
+Even numbered versions (such as 6.0) designate stable releases.
+
+Mesa version 6.0 signifies two things:
+
+  1. A stabilization of the 5.1 development release
+  2. Implementation of the OpenGL 1.5 specification.  When you query
+     glGetString(GL_VERSION) "1.5" will be returned (as long as the
+     driver supports all the required features).
+
+
+Note that the Mesa major version number is incremented with the OpenGL
+minor version number:
+
+   Mesa 1.x  ==  OpenGL 1.0
+   Mesa 2.x  ==  OpenGL 1.1
+   Mesa 3.x  ==  OpenGL 1.2
+   Mesa 4.x  ==  OpenGL 1.3
+   Mesa 5.x  ==  OpenGL 1.4
+   Mesa 6.x  ==  OpenGL 1.5
+
+
+
+New Features
+------------
+
+Mesa 5.1 already had all the new features of OpenGL 1.5, implemented as
+extensions.  These extensions were simply promoted to standard features:
+
+   GL_ARB_occlusion_query extension
+   GL_ARB_texture_non_power_of_two extension
+   GL_ARB_vertex_buffer_object extension
+   GL_EXT_shadow_funcs
+
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on
+the device driver.  For example, if the driver enables all the ARB
+extensions which are part of OpenGL 1.3 then glGetString(GL_VERSION)
+will return "1.3".  Otherwise, it'll return "1.2".
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time.  We rely on volunteers to maintain many of the drivers.
+Here's the current status of all included drivers:

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.1) designate new developmental releases.
+Even numbered versions (such as 6.0) designate stable releases.
+
+
+New Features
+------------
+
+Half-precision floating point (GLhalf) pixel formats are supported
+in Mesa, but the feature isn't exposed yet since the ARB extension
+hasn't been finalized yet.
+
+
+Texture image handling
+----------------------
+
+The code which implements image conversion, pixel transfer ops, etc
+for glTexImage commands has been rewritten.
+
+Now the gl_texture_format struct has a new StoreImage function
+pointer.  Each texture format must implement this function.  The
+function is totally responsible for converting the user's texture
+image into the specific format.  A few helper functions makes this
+relatively simple.
+
+Overall, the code is much simpler, cleaner and easier to work with
+now.  Adding new texture formats is straight-forward and there's no
+longer any distinction between "hardware" and "software" formats.
+
+Finally, the code for compressed texture images has been reorganized
+as well.
+
+Removed files:
+  texutil.c
+  texutil.h
+  texutil_tmp.h
+
+New files:
+  texcompress_s3tc.c
+  texcompress_fxt1.c
+
+
+
+Driver / context changes
+------------------------
+
+The _mesa_create_context() and _mesa_initialize_context() function
+parameters have changed.  They now take a pointer to a struct
+dd_function_table.  Drivers can initialize this table by calling
+_mesa_init_driver_functions().  Drivers should then plug in the special
+functions they implement.  In particular, the ctx->Driver.NewTextureObject
+pointer _must_ be set so that the default texture objects created in
+_mesa_create/initialize_context() are correctly built.
+
+The _mesa_init_driver_functions() function allows a lot of redundant code
+to be removed from the device drivers (such as initializing
+ctx->Driver.Accum to point to _swrast_Accum).  Adding new functions to
+the dd_function_table can be done with less hassle since the pointer can
+be initialized in _mesa_init_driver_functions() rather than in _all_ the
+drivers.
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as supporting OpenGL 1.2, 1.3, 1.4 or 1.5
+depending on the device driver's capabilities.  For example, if the
+driver enables all the ARB extensions which are part of OpenGL 1.5
+then glGetString(GL_VERSION) will return "1.5".  Otherwise, it'll
+return "1.4" or the next lower version that implements all required

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.1) designate new developmental releases.
+Even numbered versions (such as 6.2.x) designate stable releases.
+
+
+This release primarily just fixes bugs found in the Mesa 6.2 release.
+See the VERSIONS file for details.
+
+
+
+Known Issues
+------------
+
+The GL_EXT_pixel_buffer_object extension isn't fully implemented for
+functions like glPolygonStipple, glConvolutionFilter, glColorTable,
+etc.  The important functions like glRead/DrawPixels, glTex[Sub]Image,
+and glBitmap work with PBOs.  This has been fixed for Mesa 6.3.

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 6.3) designate new developmental releases.
+Even numbered versions (such as 6.2) designate stable releases.
+
+
+
+New Features
+------------
+
+GL_ARB_draw_buffers - allows a fragment program to write to a number of
+  separate color buffers, instead of just one.
+
+GL_OES_read_format - allows one to query the fastest glReadPixels format
+  and datatype.
+
+GL_ARB_pixel_buffer_object - buffer objects for pixel read/write functions.
+
+GL_EXT_framebuffer_object - allows render-to-texture and provides a
+  window-system indepedent Pbuffer facility.
+  The Mesa CVS tree contains a couple tests of this extension.
+
+DirectFB driver, contributed by Claudio Ciccani.  See docs/README.directfb
+for details.
+
+
+
+Vertex/Fragment Program PRINT Instruction
+-----------------------------------------
+
+The GL_NV_vertex_program and GL_NV_fragment_program languages have been
+extended with a PRINT instruction.
+
+
+
+glDeleteTextures(), glDeletePrograms() and glDeleteBuffers() Changed
+--------------------------------------------------------------------
+
+To match the behaviour of other OpenGL implementations, glDeleteTextures,
+glDeletePrograms and glDeleteBuffers have been modified so that:
+
+  * The named texture/program/buffer ID is immediately freed for re-use.
+
+  * The actual texture object, program or buffers isn't really deleted until
+    it is no longer bound in any rendering context (the reference count
+    is zero).
+
+Previously, the texture/program/buffer ID wasn't freed until the object
+was really deleted.
+
+Note that textures, programs and buffers can be shared by several rendering
+contexts so they can't be deleted until they're unbound in _all_ contexts.
+
+
+
+GL_EXT_framebuffer_object changes
+---------------------------------
+
+Implementing this extension involved changing a lot of code (for the better).
+
+The gl_framebuffer object now a collection of gl_renderbuffer objects.
+Renderbuffers may store colors, stencil indices, or depth values.  The
+gl_framebuffer and gl_renderbuffer types are object-oriented in design.
+
+All the old RGB, color index, stencil and depth-related span functions for
+reading/writing pixels from/to buffers has changed.  Now, all pixels are
+read/written through a set of common renderbuffer functions (methods).
+
+Most device drivers have been updated for these changes, but some haven't.
+
+
+
+To Do (someday) items
+---------------------
+ Switch to freeglut
+ Increase MAX_DRAWBUFFERS
+ driver hooks for BeginQuery/EndQuery
+
+
+
+Miscellaneous
+-------------
+
+The main/get.c file is now generated with a Python script (get_gen.py).

+<H1>Bug Database</H1>
+
+<p>
+The Mesa bug database is now hosted on
+<a href="http://freedesktop.org" target="_parent">freedesktop.org</a>
+instead of SourceForge.
+</p>
+
+<p>
+To file a Mesa bug, go to
+<a href="https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa"
+target="_parent">
+Bugzilla on freedesktop.org</a>
+</p>
+
+<p>
+Please follow these bug reporting guidelines:
+</p>
+
+<ul>
+<li>Make sure you're using the most recent version of Mesa
+<li>Make sure your bug isn't already reported
+<li>Include as much information as possible in the report
+<li>Provide a simple GLUT-based test program if possible
+<li>Check back for follow-ups to the report
+</ul>
+
+<p>
+Bug reports will automatically be forwarded to the Mesa developer's mailing
+list.
+</p>
+
+<p>
+The easier a bug is to reproduce, the sooner it will be fixed.
+Please do everything you can to facilitate quickly fixing bugs.
+If your bug report is vague or your test program doesn't compile
+easily, the problem may not be fixed very quickly.

+
+<H1>Conformance</H1>
+
+<p>
+The SGI OpenGL conformance tests verify correct operation of OpenGL
+implementations.  I, Brian Paul, have been given a copy of the tests
+for testing Mesa.  The tests are not publically available.
+</p>
+<p>
+This file has the latest results of testing Mesa with the OpenGL 1.2
+conformance tests.  Testing with the preliminary OpenGL 1.3 tests has
+also been done.  Mesa passes all the 1.3 tests.
+</p>
+<p>
+The tests were run using the software X11 device driver on 24-bpp
+and 16-bpp displays.
+</p>
+<p>
+Mesa 4.0 and later pass all conformance tests at all path levels.
+Note that this says nothing about the conformance of hardware drivers
+based upon Mesa.
+</p>
+
+

+
+COVERAGE TESTS

+
+<H1>CVS Branch Information</H1>
+
+<p>
+At any given time, there may be several active branches in Mesa's
+CVS repository.
+
+Generally, the CVS trunk contains the latest development (unstable)
+code while a CVS branch has the latest stable code.
+</p>
+
+<p>
+Currently (Oct 2004), the trunk is the Mesa 6.3 development code
+while the mesa_6_2_branch branch has the stable Mesa 6.2.x code.
+</p>
+
+<p>
+Mesa releases use an even/odd numbering scheme to represent stable/development
+releases.
+
+For example, Mesa 6.2 (0 is considered even) is a stable release while
+Mesa 6.3 is a development release.
+</p>
+
+<p>
+To checkout a specific CVS branch pass <code>-r</code> and
+the branch tag after your CVS command.
+
+For example <code>cvs checkout -r mesa_6_2_branch Mesa</code> will
+checkout the 6.2 branch and <code>cvs update -r
+mesa_6_2_branch</code> will convert your current CVS tree to the 6.2
+branch.
+
+Consult <a href="http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54"
+target="_parent">http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54</a>
+for more on branching in CVS.
+</p>
+
+<p>
+To see a list of all the CVS branches run <code>cvs log README</code> (or any
+other file) and look for the section labeled <code>symbolic names</code>.
+You'll see something like this:
+</p>
+
+<pre>  symbolic names:
+        mesa_4_0: 1.3
+        mesa_4_0_branch: 1.3.0.6
+        mesa_3_5: 1.3
+        mesa_3_4_2: 1.3
+        mesa_3_4_1: 1.3
+        mesa_3_4: 1.3
+        mesa_3_4_branch: 1.3.0.4
+        mesa_3_3: 1.3
+        mesa_3_2_1: 1.1.1.1
+        mesa_3_3_texture_env_combine2: 1.3.0.2
+        mesa_3_2: 1.1.1.1
+        mesa_3_2_beta_1: 1.1.1.1
+        mesa_3_1: 1.1.1.1
+        mesa_3_2_dev: 1.1.1.1.0.2
+        mesa_3_1_beta_3: 1.1.1.1
+        start: 1.1.1.1
+        mesa: 1.1.1
+</pre>
+
+<p>
+Most will be obsolete branches.  Generally, the newer branches are at
+the top.  Ask on the mesa3d-dev mailing list to learn which branches
+are active.

+<H1>Debugging Tips</H1>
+
+<p>
+   Normally Mesa (and OpenGL) records but does not notify the user of
+   errors.  It is up to the application to call
+   <code>glGetError</code> to check for errors.  Mesa supports an
+   environment variable, MESA_DEBUG, to help with debugging.  If
+   MESA_DEBUG is defined, a message will be printed to stdout whenever
+   an error occurs.
+</p>
+
+<p>
+   More extensive error checking is done when Mesa is compiled with the
+   DEBUG symbol defined.  You'll have to edit the Make-config file and
+   add -DDEBUG to the CFLAGS line for your system configuration.  You may
+   also want to replace any optimization flags with the -g flag so you can
+   use your debugger.  After you've edited Make-config type 'make clean'
+   before recompiling.
+</p>
+<p>
+   In your debugger you can set a breakpoint in _mesa_error() to trap Mesa
+   errors.
+</p>
+<p>
+   There is a display list printing/debugging facility.  See the end of
+   src/dlist.c for details.

+
+
+<H2>Adding Extentions</H2>
+
+<p>
+To add a new GL extension to Mesa you have to do at least the following.
+
+<ul>
+<li>
+   If glext.h doesn't define the extension, edit include/GL/gl.h and add
+   code like this:
+   <pre>
+     #ifndef GL_EXT_the_extension_name
+     #define GL_EXT_the_extension_name 1
+     /* declare the new enum tokens */
+     /* prototype the new functions */
+     /* TYPEDEFS for the new functions */
+     #endif
+   </pre>
+</li>
+<li>
+   In the src/mesa/glapi/ directory, add the new extension functions and
+   enums to the gl_API.xml file.
+   Then, a bunch of source files must be regenerated by executing the
+   corresponding Python scripts.
+</li>
+<li>
+   Find an existing extension that's similar to the new one and search
+   the sources for code related to that extension.
+   Implement new code as needed.
+   In general, new state variables will be added to mtypes.h.  If the
+   extension is rather large, try to implement it in a new source file.
+</li>
+<li>
+   If the new extension adds new GL state, the functions in get.c, enable.c
+   and attrib.c will most likely require new code.
+</li>
+</ul>
+
+
+
+<H2>Coding Style</H2>
+
+<p>
+Mesa's code style has changed over the years.  Here's the latest.
+</p>
+
+<p>
+Comment your code!  It's extremely important that open-source code be
+well documented.  Also, strive to write clean, easily understandable code.
+</p>
+
+<p>
+3-space indentation
+</p>
+
+<p>
+If you use tabs, set them to 8 columns
+</p>
+
+<p>
+Brace example:
+</p>
+<pre>
+	if (condition) {
+	   foo;
+	}
+	else {
+	   bar;
+	}
+</pre>
+
+<p>
+Here's the GNU indent command which will best approximate my preferred style:
+</p>
+<pre>
+	indent -br -i3 -npcs infile.c -o outfile.c
+</pre>
+
+
+<p>
+Local variable name example:  localVarName (no underscores)
+</p>
+
+<p>
+Constants and macros are ALL_UPPERCASE, with _ between words
+</p>
+
+<p>
+Global variables are not allowed.
+</p>
+
+<p>
+Function name examples:
+</p>
+<pre>
+	glFooBar()       - a public GL entry point (in dispatch.c)
+	_mesa_FooBar()   - the internal immediate mode function
+	save_FooBar()    - retained mode (display list) function in dlist.c
+	foo_bar()        - a static (private) function
+	_mesa_foo_bar()  - an internal non-static Mesa function
+</pre>

+
+<H2>Making a New Mesa Release</H2>
+
+<p>
+These are the instructions for making a new Mesa release.
+</p>
+
+<H3>Get latest source files</H3>
+<p>
+Use "cvs update -dAP " to get the latest Mesa files from CVS.
+</p>
+
+
+<H3>Verify and update version info</H3>
+<p>
+Create/edit the docs/RELNOTES-X.Y file to document what's new in the release.
+Add the new RELNOTES-X.Y file to <a href="relnotes.html">relnotes.html</a>.
+Update the docs/VERSIONS file too.
+</p>
+
+<p>
+Edit configs/default and change the MESA_MAJOR, MESA_MINOR and MESA_TINY
+version numbers.
+</p>
+
+<p>
+Make sure the values in src/mesa/main/version.h is correct.
+</p>
+
+<p>
+Edit the top-level Makefile and verify that DIRECTORY, LIB_NAME and
+DEMO_NAME are correct.
+</p>
+
+<p>
+Update the docs/news.html file and docs/contents.html files.
+</p>
+
+<p>
+Check in all updates to CVS.
+</p>
+
+<p>
+Tag the CVS files with the release name (in the form <b>mesa_X_Y</b>).
+</p>
+
+
+<H3>Make the tarballs</H3>
+<p>
+Make a symbolic link from $(DIRECTORY) to 'Mesa'.  For example,
+ln -s Mesa Mesa-6.3
+This is needed in order to make a correct tar file in the next step.
+</p>
+
+<p>
+Make the distribution files.  From inside the Mesa directory:
+<pre>
+	make tarballs
+</pre>
+
+<p>
+After the tarballs are created, the md5 checksums for the files will
+be computed.
+Add them to the docs/news.html file.
+</p>
+
+<p>
+Copy the distribution files to a temporary directory, unpack them,
+compile everything, and run some demos to be sure everything works.
+</p>
+
+<H3>Update the website and announce the release</H3>
+<p>
+Follow the directions on SourceForge for creating a new "release" and
+uploading the tarballs.
+</p>
+
+<p>
+Update the web site by copying the docs/ directory's files to 
+/home/users/b/br/brianp/mesa-www/htdocs/
+</p>
+
+<p>
+Make an announcement on the mailing lists:
+<em>m</em><em>e</em><em>s</em><em>a</em><em>3</em><em>d</em><em>-</em><em>d</em><em>e</em><em>v</em><em>@</em><em>l</em><em>i</em><em>s</em><em>t</em><em>s</em><em>.</em><em>s</em><em>f</em><em>.</em><em>n</em><em>e</em><em>t</em>,

+Mesa is distributed in several parts:
+</p>
+<ul>
+<li><b>MesaLib-x.y.z</b> - the main Mesa library source code, drivers
+    and documentation.
+</li>
+<li><b>MesaDemos-x.y.z</b> - OpenGL demonstration and test programs.
+    Most of the programs require GLUT (either the
+    <a href="http://www.opengl.org/resources/libraries/glut.html"

+</a><h1><a name="part1">1. High-level Questions and Answers</a></h1>
+
+<h2><a name="part1">1.1 What is Mesa?</a></h2>
+<p>
+<a name="part1">Mesa is an open-source implementation of the OpenGL specification.
+OpenGL is a programming library for writing interactive 3D applications.
+See the </a><a href="http://www.opengl.org/">OpenGL website</a> for more
+information.
+</p>
+<p>
+Mesa 6.x supports the OpenGL 1.5 specification.
+</p>
+
+
+<h2>1.2 Does Mesa support/use graphics hardware?</h2>
+<p>
+Yes.  Specifically, Mesa serves as the OpenGL core for the open-source DRI
+drivers for XFree86/X.org.  See the <a href="http://dri.sf.net/">DRI
+website</a> for more information.
+</p>
+<p>
+There have been other hardware drivers for Mesa over the years (such as
+the 3Dfx Glide/Voodoo driver, an old S3 driver, etc) but the DRI drivers
+are the modern ones.
+</p>
+
+<h2>1.3 What purpose does Mesa serve today?</h2>
+<p>
+Hardware-accelerated OpenGL implementations are available for most popular
+operating systems today.
+Still, Mesa serves at least these purposes:
+</p>
+<ul>
+<li>Mesa is used as the core of the open-source XFree86/X.org DRI
+    hardware drivers.
+</li>
+<li>Mesa is quite portable and allows OpenGL to be used on systems
+    that have no other OpenGL solution.
+</li>
+<li>Software rendering with Mesa serves as a reference for validating the
+    hardware drivers.
+</li>
+<li>A software implementation of OpenGL is useful for experimentation,
+    such as testing new rendering techniques.
+</li>
+<li>Mesa can render images with deep color channels: 16-bit integer
+    and 32-bit floating point color channels are supported.
+    This capability is only now appearing in hardware.
+</li>
+<li>Mesa's internal limits (max lights, clip planes, texture size, etc) can be
+    changed for special needs (hardware limits are hard to overcome).
+</li>
+</ul>
+
+
+<h2>1.4 What's the difference between"Stand-Alone" Mesa and the DRI drivers?</h2>
+<p>
+<em>Stand-alone Mesa</em> is the original incarnation of Mesa.
+On systems running the X Window System it does all its rendering through
+the Xlib API:
+<ul>
+<li>The GLX API is supported, but it's really just an emulation of the
+     real thing.
+<li>The GLX wire protocol is not supported and there's no OpenGL extension
+    loaded by the X server.
+<li>There is no hardware acceleration.
+<li>The OpenGL library, libGL.so, contains everything (the programming API,
+    the GLX functions and all the rendering code).
+</ul>
+</p>
+<p>
+Alternately, Mesa acts as the core for a number of OpenGL hardware drivers
+within the DRI (Direct Rendering Infrastructure):
+<ul>
+<li>The libGL.so library provides the GL and GLX API functions, a GLX
+    protocol encoder, and a device driver loader.
+<li>The device driver modules (such as r200_dri.so) contain a built-in
+    copy of the core Mesa code.
+<li>The X server loads the GLX module.
+    The GLX module decodes incoming GLX protocol and dispatches the commands
+    to a rendering module.
+    For the DRI, this module is basically a software Mesa renderer.
+</ul>
+
+
+
+<h2>1.5 How do I upgrade my DRI installation to use a new Mesa release?</h2>
+<p>
+This wasn't easy in the past.
+Now, the DRI drivers are included in the Mesa tree and can be compiled
+separately from the X server.
+Just follow the Mesa <a href="install.html">compilation instructions</a>.
+</p>
+
+
+<h2>1.6 Are there other open-source implementations of OpenGL?</h2>
+<p>
+Yes, SGI's <a href="http://oss.sgi.com/projects/ogl-sample/index.html"
+target="_parent">
+OpenGL Sample Implemenation (SI)</a> is available.
+The SI was written during the time that OpenGL was originally designed.
+Unfortunately, development of the SI has stagnated.
+Mesa is much more up to date with modern features and extensions.
+</p>
+
+<p>
+<a href="http://ogl-es.sourceforge.net" target="_parent">Vincent</a> is
+an open-source implementation of OpenGL ES for mobile devices.
+
+<p>
+<a href="http://www.dsbox.com/minigl.html" target="_parent">miniGL</a>

+</p>
+
+<p>

+</p>
+
+<p>
+<a href="http://chromium.sourceforge.net/" target="_parent">Chromium</a>
+isn't a conventional OpenGL implementation (it's layered upon OpenGL),
+but it does export the OpenGL API.  It allows tiled rendering, sort-last
+rendering, etc.
+</p>
+
+<p>
+There may be other open OpenGL implementations, but Mesa is the most
+popular and feature-complete.

+</a><h1><a name="part2">2. Compilation and Installation Problems</a></h1>
+
+
+<h2><a name="part2">2.1 What's the easiest way to install Mesa?</a></h2>
+<p>
+<a name="part2">If you're using a Linux-based system, your distro CD most likely already
+has Mesa packages (like RPM or DEB) which you can easily install.
+</a></p>
+
+
+<h2><a name="part2">2.2 Running <code>configure; make</code> doesn't Work</a></h2>
+<p>
+Mesa no longer supports GNU autoconf/automake.  Why?
+<ul>
+<li>It seemed to seldom work on anything but Linux
+<li>The config files were hard to maintain and hard to understand
+<li>libtool caused a lot of grief
+</ul>
+
+<p>
+Now Mesa again uses a conventional Makefile system (as it did originally).
+Basically, each Makefile in the tree includes one of the configuration
+files from the config/ directory.
+The config files specify all the variables for a variety of popular systems.
+</p>
+
+
+<h2><a name="part2">2.3 I get undefined symbols such as bgnpolygon, v3f, etc...</a></h2>
+<p>
+<a name="part2">You're application is written in IRIS GL, not OpenGL.
+IRIS GL was the predecessor to OpenGL and is a different thing (almost)
+entirely.
+Mesa's not the solution.
+</a></p>
+
+
+<h2><a name="part2">2.4 Where is the GLUT library?</a></h2>
+<p>
+<a name="part2">GLUT (OpenGL Utility Toolkit) is in the separate MesaGLUT-x.y.z.tar.gz file.
+If you don't already have GLUT installed, you should grab the MesaGLUT
+package and compile it with the rest of Mesa.
+</a></p>
+
+
+
+<h2><a name="part2">2.5 What's the proper place for the libraries and headers?</a></h2>
+<p>
+<a name="part2">On Linux-based systems you'll want to follow the
+</a><a href="http://oss.sgi.com/projects/ogl-sample/ABI/index.html"
+target="_parent">Linux ABI</a> standard.
+Basically you'll want the following:
+</p>
+<ul>
+<li>/usr/include/GL/gl.h - the main OpenGL header
+</li><li>/usr/include/GL/glu.h - the OpenGL GLU (utility) header
+</li><li>/usr/include/GL/glx.h - the OpenGL GLX header
+</li><li>/usr/include/GL/glext.h - the OpenGL extensions header
+</li><li>/usr/include/GL/glxext.h - the OpenGL GLX extensions header
+</li><li>/usr/include/GL/osmesa.h - the Mesa off-screen rendering header
+</li><li>/usr/lib/libGL.so - a symlink to libGL.so.1
+</li><li>/usr/lib/libGL.so.1 - a symlink to libGL.so.1.xyz
+</li><li>/usr/lib/libGL.so.xyz - the actual OpenGL/Mesa library.  xyz denotes the
+Mesa version number.
+</li><li>/usr/lib/libGLU.so - a symlink to libGLU.so.1
+</li><li>/usr/lib/libGLU.so.1 - a symlink to libGLU.so.1.3.xyz
+</li><li>/usr/lib/libGLU.so.xyz - the OpenGL Utility library.  xyz denotes the Mesa
+version number.
+</li></ul>
+<p>
+After installing XFree86/X.org and the DRI drivers, some of these files
+may be symlinks into the /usr/X11R6/ tree.
+</p>
+<p>
+The old-style Makefile system doesn't install the Mesa libraries; it's
+up to you to copy them (and the headers) to the right place.
+</p>
+<p>
+The GLUT header and library should go in the same directories.
+</p>

+</a><h1><a name="part3">3. Runtime / Rendering Problems</a></h1>
+
+<h2><a name="part3">3.1 Rendering is slow / why isn't my graphics hardware being used?</a></h2>
+<p>
+<a name="part3">Stand-alone Mesa (downloaded as MesaLib-x.y.z.tar.gz) doesn't have any
+support for hardware acceleration (with the exception of the 3DFX Voodoo
+driver).
+</a></p>
+<p>
+<a name="part3">What you really want is a DRI or NVIDIA (or another vendor's OpenGL) driver
+for your particular hardware.
+</a></p>
+<p>
+<a name="part3">You can run the <code>glxinfo</code> program to learn about your OpenGL
+library.
+Look for the GL_VENDOR and GL_RENDERER values.
+That will identify who's OpenGL library you're using and what sort of
+hardware it has detected.
+</a></p>
+<p>
+<a name="part3">If your DRI-based driver isn't working, go to the
+</a><a href="http://dri.sf.net/" target="_parent">DRI website</a> for trouble-shooting information.
+</p>
+
+
+<h2>3.2 I'm seeing errors in depth (Z) buffering.  Why?</h2>
+<p>
+Make sure the ratio of the far to near clipping planes isn't too great.
+Look
+<a href="http://www.sgi.com/software/opengl/advanced97/notes/node18.html"
+target="_parent">
+here</a> for details.
+</p>
+<p>
+Mesa uses a 16-bit depth buffer by default which is smaller and faster
+to clear than a 32-bit buffer but not as accurate.
+If you need a deeper you can modify the parameters to
+<code> glXChooseVisual</code> in your code.
+</p>
+
+
+<h2>3.3 Why Isn't depth buffering working at all?</h2>
+<p>
+Be sure you're requesting a depth buffered-visual.  If you set the MESA_DEBUG
+environment variable it will warn you about trying to enable depth testing
+when you don't have a depth buffer.
+</p>
+<p>Specifically, make sure <code>glutInitDisplayMode</code> is being called
+with <code>GLUT_DEPTH</code> or <code>glXChooseVisual</code> is being
+called with a non-zero value for GLX_DEPTH_SIZE.
+</p>
+<p>This discussion applies to stencil buffers, accumulation buffers and
+alpha channels too.
+</p>
+
+
+<h2>3.4 Why does glGetString() always return NULL?</h2>
+<p>
+Be sure you have an active/current OpenGL rendering context before
+calling glGetString.
+</p>
+
+
+<h2>3.5 GL_POINTS and GL_LINES don't touch the right pixels</h2>
+<p>
+If you're trying to draw a filled region by using GL_POINTS or GL_LINES
+and seeing holes or gaps it's because of a float-to-int rounding problem.
+But this is not a bug.
+See Appendix H of the OpenGL Programming Guide - "OpenGL Correctness Tips".
+Basically, applying a translation of (0.375, 0.375, 0.0) to your coordinates
+will fix the problem.
+</p>

+<a name="part4">
+</a><h1><a name="part4">4. Developer Questions</a></h1>
+
+<h2><a name="part4">4.1 How can I contribute?</a></h2>
+<p>
+<a name="part4">First, join the Mesa3d-dev mailing list.  That's where Mesa development
+is discussed.
+</a></p>
+<p>
+<a name="part4">The </a><a href="http://www.opengl.org/developers/documentation/specs.html" target="_parent">
+OpenGL Specification</a> is the bible for OpenGL implemention work.
+You should read it.
+</p>
+<p>Most of the Mesa development work involves implementing new OpenGL
+extensions, writing hardware drivers (for the DRI), and code optimization.
+</p>
+
+<h2>4.2 How do I write a new device driver?</h2>
+<p>
+Unfortunately, writing a device driver isn't easy.
+It requires detailed understanding of OpenGL, the Mesa code, and your
+target hardware/operating system.
+3D graphics are not simple.
+</p>
+<p>
+The best way to get started is to use an existing driver as your starting
+point.
+For a software driver, the X11 and OSMesa drivers are good examples.
+For a hardware driver, the Radeon and R200 DRI drivers are good examples.
+</p>
+<p>The DRI website has more information about writing hardware drivers.
+The process isn't well document because the Mesa driver interface changes
+over time, and we seldome have spare time for writing documentation.
+That being said, many people have managed to figure out the process.
+</p>
+<p>
+Joining the appropriate mailing lists and asking questions (and searching
+the archives) is a good way to get information.
+</p>
+
+
+<h2>4.3 Why isn't GL_EXT_texture_compression_s3tc implemented in Mesa and/or the DRI drivers?</h2>
+<p>
+The <a href="http://oss.sgi.com/projects/ogl-sample/registry/EXT/texture_compression_s3tc.txt" target="_parent">specification for the extension</a>
+indicates that there are intellectual property (IP) and/or patent issues
+to be dealt with.
+</p>
+<p>We've been unsucessful in getting a response from S3 (or whoever owns
+the IP nowadays) to indicate whether or not an open source project can
+implement the extension (specifically the compression/decompression
+algorithms).
+</p>
+<p>
+Until we can get official permission to do so, this extension will not
+be implemented in Mesa.

+<H1>1. Introduction</H1>
+
+<p>
+The fbdev/DRI sub-project within Mesa brings hardware accelerated OpenGL
+rendering to the Linux fbdev environment.
+The X Window System / XFree86 is not needed.
+</p>
+
+<p>
+Basically, the <a href="http://dri.sf.net/">DRI</a> drivers for hardware
+accelerated OpenGL for XFree86 have been ported to fbdev so that X is
+not needed.
+This means fbdev/DRI works in full-screen mode only.
+</p>
+
+<p>
+DRI driver writers may find this simplified environment easier to work in,
+compared to the full XFree86/DRI environment.
+</p>
+
+<p>
+Much of the work for this project has been done by Jon Smirl and
+Keith Whitwell.
+</p>
+
+<p>
+To use fbdev/DRI, you'll need a Linux 2.4 or 2.6 kernel.
+</p>
+
+<h3>Background Info</h3>
+
+<p>
+The Mesa-based DRI drivers used to be hosted in the DRI tree (which is
+basically a copy of the XFree86 tree).
+Since the Mesa-based DRI drivers are moreso "Mesa drivers" than "XFree86
+drivers" and the fact that with some work, the drivers could be used
+without X, the driver code was moved into the Mesa tree.
+</p>
+
+<p>
+So now the DRI drivers can be compiled for two different environments:
+fbdev and XFree86.
+To build the drivers for XFree86, one has to download/build the DRI
+source tree.
+Eventually, we'd like to be able to build the drivers for XFree86 outside
+of the XFree86/DRI trees.
+</p>
+
+
+
+
+<h1>2. Compilation</h1>
+
+<h2>2.1 Compiling the DRM modules</h2>
+
+<p>
+First, you'll need the DRM (Direct Rendering Manager) kernel module sources.
+They're found in a module of the DRI CVS tree.
+To obtain the code do the following:
+</p>
+<pre>
+   cvs -d:pserver:anonymous@pdx.freedesktop.org:/cvs/dri login
+</pre>
+<p>
+Press Enter/Return when prompted for a password.  Then,
+</p>
+<pre>
+   cvs -d:pserver:anonymous@pdx.freedesktop.org:/cvs/dri co drm
+</pre>
+
+<p>
+Compile the DRM kernel modules:
+</p>
+<pre>
+  cd drm/linux
+  make
+</pre>
+
+<p>
+Note: you may need to be root in order to make a few symlinks.
+</p>
+<p>
+When compilation is done, you should have at least the following
+kernel modules:
+</p>
+<pre>
+  gamma.o
+  i810.o
+  i830.o
+  mach64.o
+  mga.o
+  r128.o
+  radeon.o
+  savage.o
+  sis.o
+  tdfx.o
+  via.o
+</pre>
+<p>
+You'll probably want to copy/move them into your kernel module directory
+(for example: <code>/lib/modules/2.4.18-14/kernel/drivers/char/drm/</code>).
+</p>
+
+
+
+<h2>2.2 Compiling the Mesa drivers</h2>
+
+<p>
+Begin by editing the <code>Mesa/configs/default</code> file to set
+the <code>DRM_SOURCE_PATH</code> variable.
+Set it to the location where the DRM module sources are located.
+For example, if your current directory in step 2.1 was <code>/home/fred/</code>
+set DRM_SOURCE_PATH to <code>/home/fred/drm</code>
+</p>
+
+<p>
+Next, assuming you're starting with a fresh Mesa CVS checkout,
+do the following:
+</p>
+<pre>
+   make linux-solo
+</pre>
+
+<p>
+If you previously built the source tree, run <code>make realclean</code>
+first to remove the old object files.
+</p>
+
+<p>
+When this is finished, check the <code>Mesa/lib/</code> directory
+to verify that the following files were made:
+</p>
+
+<ul>
+<li><code>libGL.so.1.2</code> - the client-side OpenGL library
+    (and a few symlinks to it).
+<li><code>libGLU.so.1.1</code> - the GLU library (and a few symlinks to it).
+<li><code>libglut.so.3.7</code> - the GLUT library (and a few symlinks to it).
+<li><code>mga_dri.so</code> - DRI driver for Matrox G200/G400 cards.
+<li><code>r128_dri.so</code> - DRI driver for ATI Rage 128 cards.
+<li><code>r200_dri.so</code> - DRI driver for ATI R200 Radeon cards.
+<li><code>radeon_dri.so</code> - DRI driver for original ATI Radeon cards.
+<li><code>i810_dri.so</code> - DRI driver for Intel i810/i815 chips.
+<li><code>i830_dri.so</code> - DRI driver for Intel i830/i845 chips.
+<li><code>mga_dri.so</code> - DRI driver for Matrox G200/G400 cards.
+<li><code>sis_dri.so</code> - DRI driver for SIS cards.
+<li><code>tdfx_dri.so</code> - DRI driver for 3dfx Voodoo 3/4/5 cards.
+<li><code>gamma_dri.so</code> - DRI driver for 3Dlabs gamma cards.
+<li><code>fb_dri.so</code> - software-only fbdev driver.
+<li><code>miniglx.conf</code> - configuration file for the MiniGLX interface
+</ul>
+
+
+<h1>3. Using fbdev/DRI</h1>
+
+<p>
+If XFree86 is currently running, exit/stop the X server so you're
+working from the console.
+</p>
+
+
+<h2>3.1 Load Kernel Modules</h2>
+
+<p>
+You'll need to load the kernel modules specific to your graphics hardware.
+Typically, this consists of the agpgart module, an fbdev driver module
+and the DRM kernel module (from step 2.1).
+</p>
+
+
+<p>
+If you have ATI Radeon/R200 hardware, run as root:
+</p>
+<pre>
+   modprobe agpgart            # the AGP GART module
+   modprobe radeonfb           # the Radeon fbdev driver
+   modprobe radeon             # the Radeon DRI kernel module
+</pre>
+
+<p>
+If you have ATI Rage 128 hardware, run as root:
+</p>
+<pre>
+   modprobe agpgart            # the AGP GART module
+   modprobe aty128fb           # the Rage 128 fbdev driver
+   modprobe r128               # the Rage 128 DRI kernel module
+</pre>
+
+<p>
+If you have Matrox G200/G400 hardware, run as root:
+</p>
+<pre>
+   modprobe agpgart            # the AGP GART module
+   modprobe mgafb              # the Matrox fbdev driver
+   modprobe mga                # the Matrox DRI kernel module
+</pre>
+
+<p>
+Then run <code>lsmod</code> to be sure the modules are loaded.
+For a Radeon card, you should see something like this:
+</p>
+<pre>
+Module                  Size  Used by    Not tainted
+radeon                110308   0  (unused)
+radeonfb               21900   0  (unused)
+agpgart                43072   1 
+</pre>
+
+
+
+<h2>3.2 Configuration File</h2>
+
+<p>
+The <code>Mesa/lib/miniglx.conf</code> file should be installed
+in <code>/etc/</code>.
+</p>
+
+<p>
+Edit <code>/etc/miniglx.conf</code> to be sure it's set up correctly
+for your hardware.
+Comments in the file explain the options.
+</p>
+
+
+<h2>3.3 Running fbdev/DRI Programs</h2>
+
+<p>
+Make sure your LD_LIBRARY_PATH environment variable is set to the
+<code>Mesa/lib/</code> directory.
+</p>
+
+<p>
+Change to the <code>Mesa/progs/miniglx/</code> directory and
+start the sample_server program in the background:
+</p>
+<pre>
+   ./sample_server &
+</pre>
+
+<p>
+Then try running the <code>miniglxtest</code> program:
+</p>
+<pre>
+   ./miniglxtest
+</pre>
+<p>
+You should see a rotating quadrilateral which changes color as it rotates.
+It will exit automatically after a bit.
+</p>
+
+<p>
+If you run other tests in the miniglx/ directory, you may want to run
+them from a remote shell so that you can stop them with ctrl-C.
+</p>
+
+
+
+<h1>4.0 Troubleshooting</h1>
+
+<p>
+If you try to run miniglxtest and get the following:
+</p>
+<pre>
+   [miniglx] failed to probe chipset
+   connect: Connection refused
+   server connection lost
+</pre>
+<p>
+It means that the sample_server process is not running.
+</p>
+
+
+
+
+<h1>5.0 Programming Information</h1>
+
+<p>
+The full OpenGL API is available with fbdev/DRI.
+</p>
+
+<p>
+OpenGL/Mesa is interfaced to fbdev via the <a href="MiniGLX.html">MiniGLX</a>
+interface.
+MiniGLX is a subset of Xlib and GLX API functions which provides just
+enough functionality to setup OpenGL rendering and respond to simple
+input events.
+</p>
+
+<p>
+Since MiniGLX is a subset of the usual Xlib and GLX APIs, programs written
+to the MiniGLX API can also be run on full Xlib/GLX implementations.
+This allows some degree of flexibility for software development and testing.
+</p>
+
+<p>
+However, the MiniGLX API is not binary-compatible with full Xlib/GLX.
+Some of the structures are different and some macros/functions work
+differently.
+See the <code>GL/miniglx.h</code> header file for details.

+
+<H1>1. Introduction</H1>
+
+<p>
+The GLFBDev driver interface allows one to do OpenGL rendering into a
+framebuffer managed with the Linux's fbdev interface.
+</p>
+
+<p>
+Basically, the programmer uses the fbdev functions to initialize the
+graphics hardware and setup the framebuffer.
+Then, using a calls to Mesa's glFBDev API functions, one can render
+into the framebuffer with the OpenGL API functions.
+</p>
+
+<p>
+Note, only software rendering is supported; there is no hardware
+acceleration.
+</p>
+
+
+<p>
+The GL/glfbdev.h header file defines the glFBDev interface.
+</p>
+
+<p>
+The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface.
+</p>
+
+<p>

+<p>
+SGI open-sourced their OpenGL Sample Implementation (SI) in January, 2000.
+This includes the GLU library.
+</p>
+
+<p>
+The SI GLU library implements GLU version 1.3 whereas the original
+Mesa GLU library only implemented version 1.2.
+We recommend using the SI GLU library instead of Mesa's GLU library
+since it's more up-to-date, complete and reliable.
+We're no longer developing the original Mesa GLU library.
+</p>
+
+<p>
+The SI GLU library code is included in the Mesa distribution.
+You don't have to download it separately.
+</p>
+
+
+<p>
+<b>Olivier Michel</b> has made Linux RPMs of GLU for i386 and PowerPC.

+
+<p>
+We can always use more help with the Mesa project.
+Here are some specific ideas and areas where help would be appreciated:
+</p>
+
+<ol>
+<li><p>
+    Generate the src/mesa/main/enums.c file with a Python script which
+    uses the gl_API.xml file.
+    </p>
+<li><p>
+    Try to auto-generate the display list "save" functions seen in dlist.c
+    using a Python script and the gl_API.xml file.
+    The gl_API.xml file will probably need a new tag to indicate whether or
+    not each function gets compiled into display lists.
+    </p>
+<li><p>
+    Maintenance of assembly language files on Linux, Windows and SPARC systems.
+    </p>
+<li><p>
+    Help to incorporate the 3Dlabs' shading language compiler for OpenGL 2.0.
+    </p>
+<li><p>
+    Implement assembly language (SSE/MMX) code generation for
+    vertex/fragment programs.
+    </p>
+<li><p>
+    Windows 98/NT driver building, maintenance and testing
+    (Karl Schultz has been doing a great job of this lately).
+    </p>
+<li><p>
+    Maintenance and testing of various drivers, such as DOS/DJGPP, GGI, etc.
+    </p>
+<li><p>
+    Write new tests for Glean.
+    </p>
+</ol>
+
+
+<p>
+If you want to help with Mesa, first join the Mesa developer's
+mailing list.
+Then post a message to propose what you want to do, just to make sure
+there's no issues.
+</p>
+
+</p>
+Anyone is welcome to contribute code to the Mesa project.
+By doing so, it's assumed that you agree to the code's licensing terms.
+</p>
+
+<p>
+Finally:
+<p>
+
+<ol>
+<li>Try to write high-quality code that follows the existing style.
+<li>Use uniform indentation, write comments, use meaningful identifiers, etc.
+<li>Test your code thoroughly.  Include test programs if appropriate.
+</ol>

+
+<h3>1.1 Compilation</h3>
+
+<p>
+Mesa may be compiled in several different ways:
+</p>
+<ul>
+<li><b><em>Stand-alone/Xlib mode</em></b> - Mesa is compiled as
+a software renderer using Xlib to do all rendering.
+libGL.so is a self-contained rendering library.
+<p>
+To compile stand-alone Mesa type <b>make</b> in the top-level directory.
+You'll see a list of supported system configurations.
+Choose one from the list (such as linux-x86), and type:
+</p>
+<pre>
+    make linux-x86
+</pre>
+<p>This will produce libGL.so and several other libraries</p>
+</li>
+
+<li><b><em>DRI/accelerated</em></b> - The DRI hardware drivers (for ATI,
+Intel, Matrox, etc) are built.
+libGL.so implements the GLX extension and dynamically loads the DRI drivers.
+<p>
+To build the DRI drivers you'll first need to have the DRM (Direct
+Rendering Manager) kernel drivers and header files.
+They're available from the <a href="http://dri.sf.net/" target="_parent">DRI</a> project.
+</p>
+<p>
+You can get them from CVS by doing:
+<pre>
+cvs -d:pserver:anonymous@pds.freedesktop.org:/cvs/dri login
+(hit enter when prompted for a password)
+cvs -z3 -d:pserver:anonymous@pdx.freedesktop.org:/cvs/dri co drm
+</pre>
+<p>
+Make note of the directory in which the drm files are placed.
+</p>
+<p>
+See the <a href="http://dri.freedesktop.org/wiki/Building" target="_parent">
+DRI Building Instructions</a> for the steps to build the DRM modules.
+</p>
+<p>
+Next, in the <code>Mesa-x.y.z/configs/default</code> file, set the
+<code>DRM_SOURCE_PATH</code> variable to indicate where the DRM files
+are located.
+</p>
+<p>
+Now build Mesa and the DRI drivers by running
+</p>
+<pre>
+make linux-dri
+</pre>
+<p>
+There are also <code>linux-dri-x86</code>, <code>linux-dri-x86-64</code>, 
+and <code>linux-ppc</code> configurations, optimized for those architectures.
+</p>

+Finally, you'll need a DRI-enabled X server from
+<a href="http://freedesktop.org/wiki/Software_2fXserver" target="_parent">
+X.org</a> or <a href="http://www.xfree86.org" target="_parent">XFree86</a>.

+<h3>1.3 Running the demos</h3>
+
+<p>
+If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or
+obtained Mesa from CVS, the <b>progs/</b> directory will contain a
+bunch of demonstration programs.
+</p>
+
+<p>
+Before running a demo, you may have to set an environment variable
+(such as <b>LD_LIBRARY_PATH</b> on Linux) to indicate where the
+libraries are located.  For example:
+<p>
+<blockquote>
+<b>cd</b> into the Mesa <b>lib/</b> directory.
+<br>
+<b>setenv LD_LIBRARY_PATH ${cwd}</b>   (if using csh or tcsh shell)
+<br>
+or,
+<br>
+<b>export LD_LIBRARY_PATH=${PWD}</b>   (if using bash or sh shell)
+</blockquote>
+
+<p>
+Next, change to the Mesa/demos/ directory:
+</p>
+<blockquote>
+<b>cd ../progs/demos</b>
+</blockquote>
+
+<p>
+Run a demo such as gears:
+</p>
+<blockquote>
+<b>./gears</b>
+</blockquote>
+
+<p>
+If this doesn't work, try the <b>Mesa/progs/xdemos/glxinfo</b> program
+and see that it prints the expected Mesa version number.
+</p>
+
+<p>
+If you're using Linux or a similar OS, verify that the demo program is
+being linked with the proper library files:
+</p>
+<blockquote>
+<b>ldd gears</b>
+</blockquote>
+
+<p>
+You should see something like this:
+</p>
+<pre>
+        libglut.so.3 => /home/brian/Mesa/lib/libglut.so.3 (0x40013000)

+Retrace your steps if this doesn't look right.

+
+
+<H3>1.4 Installing the header and library files</H3>
+
+<p>
+The standard location for the OpenGL header files on Unix-type systems is
+in <code>/usr/include/GL/</code>.
+The standard location for the libraries is <code>/usr/lib/</code>.
+For more information see, the
+<a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
+Linux/OpenGL ABI specification</a>.
+</p>
+
+<p>
+If you'd like Mesa to co-exist with another implementation of OpenGL that's
+already installed, you'll have to choose different directories, like
+<code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
+</p>
+
+<p>
+To install Mesa's headers and libraries, run <code>make install</code>
+You'll be prompted to enter alternative directories for the headers
+and libraries.
+</p>
+
+<p>
+Note: at runtime, you can set the LD_LIBRARY_PATH (on Linux) to switch
+between the Mesa libs and another vendor libs whenever you want.
+This is a handy way to compare multiple OpenGL implementations.

+<BODY>
+
+<H1>Introduction</H1>
+
+<p>
+Mesa is a 3-D graphics library with an API which is very similar to
+that of <a href="http://www.opengl.org/" target="_parent">OpenGL</a>.*
+To the extent that Mesa utilizes the OpenGL command syntax or state
+machine, it is being used with authorization from <a
+href="http://www.sgi.com/" target="_parent">Silicon Graphics,
+Inc.</a>(SGI). However, the author does not possess an OpenGL license
+from SGI, and makes no claim that Mesa is in any way a compatible
+replacement for OpenGL or associated with SGI. Those who want a
+licensed implementation of OpenGL should contact a licensed
+vendor.
+</p>
+
+<p>
+Please do not refer to the library as <em>MesaGL</em> (for legal
+reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
+library</em>. <br>
+</p>
+
+<p>
+* OpenGL is a trademark of <a href="http://www.sgi.com/"
+target="_parent">Silicon Graphics Incorporated</a>.
+</p>
+
+
+<H1>Project History</H1>
+
+<p>
+The Mesa project was founded by me, Brian Paul.  Here's a short history
+of the project.
+</p>
+
+<p>
+August, 1993: I begin working on Mesa in my spare time.  The project
+has no name at that point.  I was simply interested in writing a simple
+3D graphics library that used the then-new OpenGL API.  I was partially
+inspired by the <em>VOGL</em> library which emulated a subset of IRIS GL.
+I had been programming with IRIS GL since 1991.
+</p>
+
+<p>
+November 1994: I contact SGI to ask permission to distribute my OpenGL-like
+graphics library on the internet.  SGI was generally receptive to the
+idea and after negotiations with SGI's legal department, I get permission
+to release it.
+</p>
+
+<p>
+February 1995: Mesa 1.0 is released on the internet.  I expected that
+a few people would be interested in it, but not thousands.
+I was soon receiving patches, new features and thank-you notes on a
+daily basis.  That encouraged me to continue working on Mesa.  The
+name Mesa just popped into my head one day.  SGI had asked me not to use
+the terms <em>"Open"</em> or <em>"GL"</em> in the project name and I didn't
+want to make up a new acronym.  Later, I heard of the Mesa programming
+language and the Mesa spreadsheet for NeXTStep.
+</p>
+
+<p>
+In the early days, OpenGL wasn't available on too many systems.
+It even took a while for SGI to support it across their product line.
+Mesa filled a big hole during that time.
+For a lot of people, Mesa was their first introduction to OpenGL.
+I think SGI recognized that Mesa actually helped to promote
+the OpenGL API, so they didn't feel threatened by the project.
+</p>
+
+
+<p>
+1995-1996: I continue working on Mesa both during my spare time and during
+my work hours at the Space Science and Engineering Center at the University
+of Wisconsin in Madison.  My supervisor, Bill Hibbard, lets me do this because
+Mesa is now being using for the <a href="http://www.ssec.wisc.edu/%7Ebillh/vis.html" target="_parent">Vis5D</a> project.
+</p><p>
+October 1996: Mesa 2.0 is released.  It implements the OpenGL 1.1 specification.
+</p>
+
+<p>
+March 1997: Mesa 2.2 is released.  It supports the new 3dfx Voodoo graphics
+card via the Glide library.  It's the first really popular hardware OpenGL
+implementation for Linux.
+</p>
+
+<p>
+September 1998: Mesa 3.0 is released.  It's the first publicly-available
+implementation of the OpenGL 1.2 API.
+</p>
+
+<p>
+March 1999: I attend my first OpenGL ARB meeting.  I contribute to the
+development of several official OpenGL extensions over the years.
+</p>
+
+<p>
+September 1999: I'm hired by Precision Insight, Inc.  Mesa is a key
+component of 3D hardware acceleration in the new DRI project for XFree86.
+Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon follow.
+</p>
+
+<p>
+October 2001: Mesa 4.0 is released.
+It implements the OpenGL 1.3 specification.
+</p>
+
+
+<p>
+November 2001: I cofound <a href="http://www.tungstengraphics.com" target="_parent">
+Tungsten Graphics, Inc.</a> with Keith Whitwell, Jens Owen, David Dawes and
+Frank LaMonica.
+I continue to develop Mesa as part of my resposibilities with Tungsten
+Graphics and as a spare-time project.
+</p>
+
+<p>
+November 2002: Mesa 5.0 is released.
+It implements the OpenGL 1.4 specification.
+</p>
+
+<p>
+January 2003: Mesa 6.0 is released.  It implements the OpenGL 1.5
+specification as well as the GL_ARB_vertex_program and
+GL_ARB_fragment_program extensions.
+</p>
+
+
+<p>
+Ongoing: Mesa is used as the core of many hardware OpenGL drivers for
+the XFree86 X.org X servers within the
+<A href="http://dri.sourceforge.net/" target="_parent">DRI project</A>.
+I continue to enhance Mesa with new extensions and features.
+</p>
+
+
+
+<H1>Major Versions</H1>
+
+<p>
+This is a summary of the major versions of Mesa.  Note that Mesa's major
+version number tracks OpenGL's minor version number (+1).
+Work is underway to implement the OpenGL 2.0 specification.

+<H1>Function Name Mangling</H1>
+
+<p>
+If you want to use Mesa and native OpenGL in the same application at
+the same time you may find it useful to compile Mesa with
+<i>name mangling</i>.
+This results in all the Mesa functions being prefixed with
+<b>mgl</b> instead of <b>gl</b>.
+</p>
+
+<p>
+To do this, recompile Mesa with the compiler flag -DUSE_MGL_NAMESPACE.
+Add the flag to the other compiler flags in Make-config (if using the
+old-style build system) or in src/Makefile if using GNU autoconf/
+automake to build Mesa.

+
+<H1>Off-screen Rendering</H1>
+
+
+<p>
+Mesa 1.2.4 introduced off-screen rendering, a facility for generating
+3-D imagery without having to open a window on your display.  Mesa's
+simple off-screen rendering interface is completely operating system
+and window system independent so programs which use off-screen
+rendering should be very portable.  This feature effectively
+enables you to use Mesa as an off-line, batch-oriented renderer.
+</p>
+<p>
+The "OSMesa" API provides 3 functions for making off-screen
+renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and
+OSMesaDestroyContext().  See the Mesa/include/GL/osmesa.h header for
+more information.  See the demos/osdemo.c file for an example program.
+There is no facility for writing images to files.  That's up to you.
+</p>
+<p>
+If you want to generate large images (larger than 1280x1024) you'll
+have to edit the src/config.h file to change MAX_WIDTH and MAX_HEIGHT
+then recompile Mesa.  Image size should only be limited by available
+memory.
+</p>
+
+
+<H2>Deep color channels</H2>
+
+<p>
+   For some applications 8-bit color channels don't have sufficient
+   accuracy (film and IBR, for example).  If you're in this situation
+   you'll be happy to know that Mesa supports 16-bit and 32-bit color
+   channels through the OSMesa interface.  When using 16-bit channels,
+   channels are GLushorts and RGBA pixels occupy 8 bytes.  When using 32-bit
+   channels, channels are GLfloats and RGBA pixels occupy 16 bytes.
+</p>
+<p>
+   To build Mesa/OSMesa with 16-bit color channels:
+<pre>
+      make realclean
+      make linux-osmesa16
+</pre>
+
+   For 32-bit channels:
+<pre>
+      make realclean
+      make linux-osmesa32
+</pre>
+
+<p>
+You'll wind up with a library named libOSMesa16.so or libOSMesa32.so.
+</p>
+
+<p>
+If you need to compile on a non-Linux platform, copy Mesa/configs/linux-osmesa16
+to a new config file and edit it as needed.  Then, add the new config name to
+the top-level Makefile.  Send a patch to the Mesa developers too, if you're
+inclined.
+</p>
+
+<p>
+BE WARNED: 16 and 32-bit channel support has not been exhaustively
+tested and there may be some bugs.  However, a number of people have
+been using this feature successfully so it can't be too broken.

+<BODY>
+
+<H1>PBuffer Rendering</H1>
+
+<p>
+Basically, FBconfigs and PBuffers allow you to do off-screen rendering
+with OpenGL.  The OSMesa interface does basically the same thing, but
+fbconfigs and pbuffers are supported by more vendors.
+PBuffer rendering may also be hardware accelerated.
+</p>
+
+<p>
+PBuffers are getting more use nowadays, though they've actually been
+around for a long time on IRIX systems and other workstations.
+</p>
+
+<p>
+The
+<a href="http://oss.sgi.com/projects/ogl-sample/registry/SGIX/fbconfig.txt"
+target="_parent">GL_SGIX_fbconfig</a>
+and
+<a href="http://oss.sgi.com/projects/ogl-sample/registry/SGIX/pbuffer.txt"
+target="_parent">
+GL_SGIX_pbuffer</a> extensions describe the functionality.
+More recently, these extensions have been promoted to ARB extensions (on
+Windows at least).
+</p>
+
+<p>
+The Mesa/progs/xdemos/ directory has some useful code for working
+with pbuffers:
+</p>
+
+<ul>
+<li><b>pbinfo.c</b> - like glxinfo, it prints a list of available
+    fbconfigs and whether each supports pbuffers.
+<li><b>pbutil.c</b> - a few utility functions for dealing with
+    fbconfigs and pbuffers.
+<li><b>pbdemo.c</b> - a demonstration of off-screen rendering with pbuffers.
+</ul>
+
+<p>
+Mesa 4.1 and later support GL_SGIX_fbconfig and GL_SGIX_pbuffer (software
+rendering only).

+
+<BODY>
+
+<H1>Performance Tips</H1>
+
+<p>
+Performance tips for software rendering:
+</P>
+<ol>
+
+<li> Turn off smooth shading when you don't need it (glShadeModel)
+<li> Turn off depth buffering when you don't need it.
+<li> Turn off dithering when not needed.
+<li> Use double buffering as it's often faster than single buffering
+<li> Compile in the X Shared Memory extension option if it's supported
+      on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for
+      your system in the Make-config file.
+<li> Recompile Mesa with more optimization if possible.
+<li> Try to maximize the amount of drawing done between glBegin/glEnd pairs.
+<li> Use the MESA_BACK_BUFFER variable to find best performance in double
+      buffered mode.  (X users only)
+<li> Optimized polygon rasterizers are employed when:
+         rendering into back buffer which is an XImage
+         RGB mode, not grayscale, not monochrome
+         depth buffering is GL_LESS, or disabled
+         flat or smooth shading
+         dithered or non-dithered
+         no other rasterization operations enabled (blending, stencil, etc)
+<li> Optimized line drawing is employed when:
+         rendering into back buffer which is an XImage
+         RGB mode, not grayscale, not monochrome
+         depth buffering is GL_LESS or disabled
+         flat shading
+         dithered or non-dithered
+         no other rasterization operations enabled (blending, stencil, etc)
+<li> Textured polygons are fastest when:
+         using a 3-component (RGB), 2-D texture
+         minification and magnification filters are GL_NEAREST
+         texture coordinate wrap modes for S and T are GL_REPEAT
+         GL_DECAL environment mode
+         glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST )
+         depth buffering is GL_LESS or disabled
+<li> Lighting is fastest when:
+         Two-sided lighting is disabled
+         GL_LIGHT_MODEL_LOCAL_VIEWER is false
+         GL_COLOR_MATERIAL is disabled
+         No spot lights are used (all GL_SPOT_CUTOFFs are 180.0)
+         No local lights are used (all position W's are 0.0)
+         All material and light coefficients are >= zero
+<li> XFree86 users:  if you want to use 24-bit color try starting your
+      X server in 32-bit per pixel mode for better performance.  That is,
+      start your X server with
+         startx -- -bpp 32
+      instead of
+         startx -- -bpp 24
+<li> Try disabling dithering with the MESA_NO_DITHER environment variable.
+      If this env var is defined Mesa will disable dithering and the
+      command glEnable(GL_DITHER) will be ignored.

+The <span style="font-weight: bold;">glMatrixMode</span> command
+specifies the <span style="font-style: italic;">current matrix.</span>
+&nbsp;The mode parameter may be GL_MODELVIEW or GL_PROJECTION to specify
+the modelview matrix or projection matrix. &nbsp;Subsequent matrix
+commands will effect the current matrix. &nbsp;Also associated with the
+modelview and projection matrices are a modelview matrix stack and
+projection matrix stack.<br>
+<br>
+The <span style="font-weight: bold;">glLoadIdentity</span> command
+replaces the current matrix with the identity matrix. &nbsp;The matrix
+elements are specified in column-major order.<br>
+<br>
+The <span style="font-weight: bold;">glPushMatrix</span> command pushes
+a copy of the current matrix onto either the modelview matrix stack or
+the projection matrix stack. &nbsp;The <span style="font-weight: bold;">glPopMatrix</span>
+command replaces the current matrix with a copy of the top matrix off
+the modelview matrix stack or projection matrix stack, the pops the
+stack. &nbsp;Matrix stacks are useful for traversing and rendering
+hierarchical models.<br>
+<br>
+The <span style="font-weight: bold;">glMultMatrixf</span> command
+post-multiplies the current matrix by the specified matrix. &nbsp;The
+matrix elements are specified in column-major order.<br>
+<br>
+The <span style="font-weight: bold;">glRotatef</span> command
+post-multiplies the current matrix by a rotation matrix defined by the
+angle and rotation axis defined by x, y and z.<br>
+<br>
+The <span style="font-weight: bold;">glTranslatef</span> command
+post-multiplies the current matrix by a translation matrix defined by
+the <span style="font-style: italic;">x</span>, <span
+ style="font-style: italic;">y</span> and <span
+ style="font-style: italic;">z</span> translation parameters.<br>
+<span style="font-weight: bold;"></span><br>

+<span style="font-weight: bold;"></span><br>
+The <span style="font-weight: bold;">glFrustum</span> command
+post-multiplies the current matrix by a perspective projection matrix.
+&nbsp;The <span style="font-style: italic;">near</span> and <span
+ style="font-style: italic;">far</span> values specify the position of
+the hither and yon Z-axis clipping planes. &nbsp;The <span
+ style="font-style: italic;">left, right, bottom</span> and <span
+ style="font-style: italic;">top</span> parameters are the X and Y
+extents at the near clipping plane. &nbsp;<span
+ style="font-weight: bold;">glFrustum</span> is normally used to modify
+the projection matrix.<br>
+<br>
+The <span style="font-weight: bold;">glOrtho</span> command
+post-multiplies the current matrix by an orthographic projection matrix.
+&nbsp;The <span style="font-style: italic;">near</span> and <span
+ style="font-style: italic;">far</span> values specify the position of
+the hither and yon Z-axis clipping planes. &nbsp;The <span
+ style="font-style: italic;">left, right, bottom</span> and <span
+ style="font-style: italic;">top</span> parameters specify the X and
+Y-axis clipping planes. &nbsp;<span style="font-weight: bold;">glOrtho</span>
+is normally used to modify the projection matrix.<br>
+<br>
+The <span style="font-weight: bold;">glViewport</span> command
+specifies the mapping of coordinates from normalized device coordinates
+to window coordinates. &nbsp;The <span style="font-style: italic;">x</span>
+and <span style="font-style: italic;">y</span> parameters specify the
+viewport's lower-left corner in the window and the <span
+ style="font-style: italic;">width</span> and <span
+ style="font-style: italic;">height</span> parameters specify the size
+of the viewport. &nbsp;<span style="font-weight: bold;">glViewport</span>
+does not effect the current matrix.<br>
+<br>
+A coordinate transformed to window coordinates is hereafter known as (x<sub>w</sub>,
+y<sub>w</sub>, z<sub>w</sub>).<br>
+<br>
+<h2>3.2 Clipping</h2>
+View-volume clipping automatically discards or trims primitives which
+lie completely or partially outside of the view volume specified by <span
+ style="font-weight: bold;">glFrustum</span> and <span
+ style="font-weight: bold;">glOrtho</span>. &nbsp;Note that the <span
+ style="font-weight: bold;">glViewport</span> command does not define a
+clipping region.<br>
+<br>
+Clipping occurs in <span style="font-style: italic;">clip coordinate
+space - </span>the coordinates produced after applying the projection
+matrix.<br>
+<br>
+<h2>3.3 Current Raster Position</h2>
+The current raster position specifies the location for drawing images
+with <span style="font-weight: bold;">glBitmap.</span> &nbsp;The current
+raster position is set with the commands:<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glRasterPos2f</span>(GLfloat<span
+ style="font-style: italic;">x</span>, GLfloat <span
+ style="font-style: italic;">y</span>)<br>

+ style="font-style: italic;">y</span>)<br>
+void <span style="font-weight: bold;">glRasterPos2iv</span>(const
+GLint *<span style="font-style: italic;">v</span>)<br>
+</div>
+<br>
+<span style="font-weight: bold;">glRasterPos</span> specifies a
+4-component coordinate (x, y, 0, 1). &nbsp;The coordinate is processed
+like a vertex; it is transformed by the modelview matrix, the projection
+matrix and mapped to the viewport. &nbsp;The resulting window coordinate
+is stored as the current raster position. &nbsp;The coordinate is
+clipped-tested against the frustum like a vertex. &nbsp;If the
+coordinate is clipped, then the current raster position becomes invalid
+and subsequent <span style="font-weight: bold;">glBitmap</span> commands
+have no effect.<br>
+<br>
+<span style="font-weight: bold;">glRasterPos</span> also updates the
+current raster color and current raster texture coordinates. &nbsp;The
+current raster color is updated (copied) from the current color (as
+specified by <span style="font-weight: bold;">glColor</span>).
+&nbsp;The current raster texture coordinate is updated (copied) from the
+current texture coordinate (as specified by <span
+ style="font-weight: bold;">glTexCoord</span>).<br>

+<h1>4. Rasterization</h1>
+This section describes the commands and options for drawing points,
+lines, triangles and bitmaps. &nbsp;<span style="font-style: italic;">Rasterization</span>
+is the term for the process which produces fragments from the geometric
+description of a primitive (a point, line, polygon or bitmap). &nbsp;For
+example, given the two coordinates for the end-points of a line segment,
+rasterization determines which pixels in the frame buffer are modified
+to <span style="font-style: italic;">draw</span> the line. &nbsp;A
+fragment is a tuple which consists of a window coordinate, colors and
+texture coordinates. &nbsp;The fragments produced by rasterization are
+subsequently processed by the per-fragment operations described later.<br>
+<br>
+<h2>4.1 Point Rasterization</h2>
+Points are rendered with the command sequence <span
+ style="font-weight: bold;">glBegin</span>(GL_POINTS), <span
+ style="font-weight: bold;">glVertex</span>, ... <span
+ style="font-weight: bold;">glEnd</span>. &nbsp;The window coordinate (x<sub>w</sub>,
+y<sub>w</sub>, z<sub>w</sub>) is truncated to rasterize the point.
+&nbsp;The truncated coordinate with its associated color and texture
+coordinate is sent as a single fragment to the per-fragment processing
+stages.<br>
+<br>
+The <span style="font-weight: bold;">glPointSize</span> command is not
+supported; only 1-pixel points are supported.<br>
+<br>
+Point smoothing (antialiasing) is also not supported.<br>
+<br>
+<h2>4.2 Line Rasterization</h2>
+Lines are rendered with the command sequence <span
+ style="font-weight: bold;">glBegin</span>(<span
+ style="font-style: italic;">mode</span>), <span
+ style="font-weight: bold;">glVertex</span>, <span
+ style="font-weight: bold;">glVertex</span>, ... <span
+ style="font-weight: bold;">glEnd</span> where <span
+ style="font-style: italic;">mode</span> is one of GL_LINES,
+GL_LINE_STRIP or GL_LINE_LOOP. &nbsp;Lines are rasterized as described
+in the OpenGL specification. &nbsp;Note that OpenGL specifies the <span
+ style="font-style: italic;">half-open</span> convention for drawing
+lines: the last fragment in a line segment is omitted so that endpoint
+pixels shared by two line segments will only be drawn once instead of
+twice.<br>
+<br>
+<h3>4.2.1 Line Width</h3>
+The width of lines can be controlled by<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glLineWidth</span>(GLfloat<span
+ style="font-style: italic;">width</span>)<br>
+</div>
+<br>
+where <span style="font-style: italic;">width</span> is the line width
+in pixels. &nbsp;The width defaults to 1.0. &nbsp;Attempting to set the
+width to a value less than or equal to zero will raise the error
+GL_INVALID_VALUE.<br>
+<br>
+<h3>4.2.2 Line Stipple<br>
+</h3>
+Lines may be stippled (i.e. dashed) with the command<br>
+<br>
+<div style="margin-left: 40px;"><span style="font-weight: bold;">glLineStipple</span>(GLint<span
+ style="font-style: italic;">factor</span>, GLushort <span
+ style="font-style: italic;">pattern</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">pattern</span> describes an on/off
+pattern for the fragments produced by rasterization and <span
+ style="font-style: italic;">factor</span> specifies how many subsequent
+fragments are kept or culled for each pattern bit. &nbsp;Line stippling
+can be enabled or disabled by the commands <span
+ style="font-weight: bold;">glEnable</span>(GL_LINE_STIPPLE) and <span
+ style="font-weight: bold;">glDisable</span>(GL_LINE_STIPPLE).<br>
+<br>
+<h3>4.2.3 Line Antialiasing</h3>
+Lines may be antialiased. &nbsp;For antialiased lines, each fragment
+produced by rasterization is assigned a <span
+ style="font-style: italic;">coverage value</span> which describes how
+much of the fragment's area is considered to be <span
+ style="font-style: italic;">inside</span> the line. &nbsp;Later, the
+alpha value of each fragment is multiplied by the coverage value.
+&nbsp;By blending the fragments into the frame buffer, the edges of
+lines appear smoothed.<br>
+<br>
+Line antialiasing can be enabled or disabled with the commands <span
+ style="font-weight: bold;">glEnable</span>(GL_LINE_SMOOTH) and <span
+ style="font-weight: bold;">glDisable</span>(GL_LINE_SMOOTH).<br>
+<br>
+<h2>4.3 Polygon Rasterization</h2>
+Polygons, quadrilaterals and triangles share the same polygon
+rasterization options. <br>
+<br>
+Triangles are rendered by the command sequence <span
+ style="font-weight: bold;">glBegin</span><span
+ style="font-style: italic;"><span style="font-style: italic;">(mode</span></span>),<span
+ style="font-weight: bold;">glVertex</span>, <span
+ style="font-weight: bold;">glVertex</span>, ... <span
+ style="font-weight: bold;">glEnd</span> where <span
+ style="font-style: italic;">mode</span> may be one of GL_TRIANGLES,
+GL_TRIANGLE_STRIP or GL_TRIANGLE_FAN.<span style="font-weight: bold;"></span>
+&nbsp;For GL_TRIANGLES mode, the number of vertices should be a multiple
+of three - extra vertices will be ignored. &nbsp;For GL_TRIANGLE_STRIP
+and GL_TRIANGLE_FAN, at least three vertices should be specified.
+&nbsp;If less than three are specified, nothing is drawn. &nbsp;<br>
+<br>
+Quadrilaterals are <span style="font-weight: bold;"></span>rendered by
+the command sequence <span style="font-weight: bold;">glBegin</span>(<span
+ style="font-style: italic;"><span style="font-style: italic;">mode</span></span>),<span
+ style="font-weight: bold;">glVertex</span>, <span
+ style="font-weight: bold;">glVertex</span>, ... <span
+ style="font-weight: bold;">glEnd</span> where <span
+ style="font-style: italic;">mode</span> may be one of GL_QUADS or
+GL_QUAD_STRIP.<span style="font-weight: bold;"></span> &nbsp; For
+GL_QUADS, the number of vertices should be a multiple of four - extra
+vertices will be ignored. &nbsp;For GL_QUAD_STRIP, the number of
+vertices should be even and at least four. &nbsp;Extra vertices (one)
+will be ignored.<br>
+<br>
+Convex polygons are <span style="font-weight: bold;"></span>rendered
+by the command sequence <span style="font-weight: bold;">glBegin</span><span
+ style="font-style: italic;"><span style="font-style: italic;"></span></span>(GL_POLYGON),<span
+ style="font-weight: bold;">glVertex</span>, <span
+ style="font-weight: bold;">glVertex</span>, ... <span
+ style="font-weight: bold;">glEnd</span>.<span
+ style="font-style: italic;"></span><span style="font-weight: bold;"></span>
+&nbsp;If less than three vertices are specified, nothing is drawn.<br>
+<br>
+<h3>4.3.1 Polygon Orientation</h3>
+The <span style="font-style: italic;">winding order</span> of vertices
+(clockwise or counter-clockwise) is significant. &nbsp;It is used to
+determine the <span style="font-style: italic;">front-facing</span> or <span
+ style="font-style: italic;">back-facing</span> orientation of polygons.
+&nbsp;By default, a front-facing polygon's vertices are in
+counter-clockwise order (in window coordinates). &nbsp;Figures 2.4 and
+2.5 of the OpenGL 1.2.1 specification illustrate the winding order for
+front-facing triangles and quadrilaterals, respectively.<br>
+<br>
+The command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glFrontFace</span>(GLenum<span
+ style="font-style: italic;"> mode</span>)<br>
+</div>
+<br>
+specifies whether clockwise or counter-clockwise winding indicates a
+front-facing polygon. &nbsp;If <span style="font-style: italic;">mode</span>
+is GL_CW then polygons with clockwise winding are front-facing. &nbsp;If <span
+ style="font-style: italic;">mode</span> is GL_CCW then polygons with
+counter-clockwise winding are front-facing. &nbsp;The default value is
+GL_CCW. &nbsp;If <span style="font-style: italic;">mode</span> is not
+GL_CCW or GL_CW then the error GL_INVALID_ENUM will be raised.<span
+ style="font-style: italic;"></span><span style="font-style: italic;"></span><br>
+<br>
+<h3>4.3.2 Polygon Culling</h3>
+Polygons may be culled (discarded) depending on whether they are
+front-facing or back-facing. &nbsp;The command<br>
+<br>
+<div style="margin-left: 40px;">void<span style="font-weight: bold;">
+glCullFace</span>(GLenum <span style="font-style: italic;">mode</span>)<br>
+</div>
+<br>
+specifies whether front-facing, back-facing or all polygons should be
+culled. &nbsp;If <span style="font-style: italic;">mode</span> is
+GL_FRONT then front-facing polygons will be culled. &nbsp;If <span
+ style="font-style: italic;">mode</span> is GL_BACK then back-facing
+polygons will be culled. Otherwise, if <span style="font-style: italic;">mode</span>
+is GL_FRONT_AND_BACK then all polygons will be culled. &nbsp;Any other
+value for <span style="font-style: italic;">mode</span> will raise the
+error GL_INVALID_ENUM.<br>
+<br>
+Polygon culling is enabled and disabled with the commands <span
+ style="font-weight: bold;">glEnable</span>(GL_CULL_FACE) and <span
+ style="font-weight: bold;">glDisable</span>(GL_CULL_FACE),
+respectively.<br>
+<br>
+<h3>4.3.3 Polygon Antialiasing</h3>
+Polygons may be antialiased in order to smooth their edges.
+&nbsp;Polygon antialiasing is enabled and disabled with the commands <span
+ style="font-weight: bold;">glEnable</span>(GL_POLYGON_SMOOTH) and <span
+ style="font-weight: bold;">glDisable</span>(GL_POLYGON_SMOOTH).<br>
+<br>
+When polygon antialiasing is enabled each fragment produced by polygon,
+triangle and quadrilateral rasterization will be given a <span
+ style="font-style: italic;">coverage</span> value which indicates how
+much of the fragment is covered by the polygon. &nbsp;Fragments
+completely inside the polygon have coverage 1.0. &nbsp;Fragments
+completely outside the polygon have zero coverage (in theory).
+&nbsp;Fragments which intersect the polygon's edge have a coverage value
+in the range (0, 1).<br>
+<br>
+The fragment's alpha value is multiplied by the coverage value.
+&nbsp;By enabling the appropriate blending mode, polygon edges will
+appear smoothed.<br>
+<br>
+<h2>4.4 Shading</h2>
+The command<br>
+<br>
+<div style="margin-left: 40px;"> void <span style="font-weight: bold;">glShadeModel</span>(GLenum<span
+ style="font-style: italic;">mode</span>)<br>
+</div>
+<br>
+determines whether colors are interpolated between vertices during
+rasterization. &nbsp;If <span style="font-style: italic;">mode</span> is
+GL_FLAT then vertex colors are not interpolated. &nbsp;The color used
+for drawing lines, triangles and quadrilaterals is that of the last
+vertex used to specify each primitive. &nbsp;For polygons, the color of
+the first vertex specifies the color for the entire polygon. &nbsp;If <span
+ style="font-style: italic;">mode</span> is GL_SMOOTH then vertex colors
+are linearly interpolated to produce the fragment colors.<br>
+<br>
+<h2>4.5 Bitmap Rasterization</h2>
+A bitmap is a monochromatic, binary image in which each image element
+(or pixel) is represented by one bit. &nbsp;Fragments are only generated
+for the bits (pixels) which are set.  &nbsp;Bitmaps are commonly used to
+draw text (glyphs) and markers.<br>
+<br>
+A bitmap is drawn with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glBitmap</span>(GLsizei<span
+ style="font-style: italic;">width</span>, GLsizei <span
+ style="font-style: italic;">height</span>, GLfloat <span
+ style="font-style: italic;">xOrig</span>, GLfloat <span
+ style="font-style: italic;">yOrig</span>, GLfloat <span
+ style="font-style: italic;">xMove</span>, GLfloat <span
+ style="font-style: italic;">yMove</span>, const &nbsp;GLubyte *<span
+ style="font-style: italic;">image</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">width </span>and <span
+ style="font-style: italic;">height</span> specify the image size in
+pixels. &nbsp;<span style="font-style: italic;">xOrig</span> and <span
+ style="font-style: italic;">yOrig</span> specify the bitmap origin.
+&nbsp;<span style="font-style: italic;">xMove</span> and <span
+ style="font-style: italic;">yMove</span> are added to the current
+raster position after the bitmap is rasterized. &nbsp;<span
+ style="font-style: italic;">image</span> is a pointer to the bitmap
+data.<br>
+<br>
+If the current raster position is not valid, <span
+ style="font-weight: bold;">glBitmap</span> has no effect.<br>
+<br>
+<h3>4.5.1 Bitmap Unpacking</h3>
+The first step in bitmap rendering is <span style="font-style: italic;">unpacking.
+&nbsp;</span>Unpacking is the process of extracting image data from
+client memory subject to byte swapping, non-default row strides, etc.
+&nbsp;The unpacking parameters are specified with the command<br>
+<br>
+<div style="margin-left: 40px;">void<span style="font-weight: bold;">
+glPixelStorei</span>(GLenum pname, GLint value)<br>
+</div>
+<span style="font-style: italic;"></span><br>
+The following unpacking parameters may be set:<br>
+<br>
+<table cellpadding="2" cellspacing="2" border="1"
+ style="text-align: left; width: 90%; margin-left: auto; margin-right: auto;">
+  <tbody>

+      <td style="vertical-align: top;">GL_UNPACK_LSB_FIRST<br>
+      </td>
+      <td style="vertical-align: top;">GL_FALSE indicates that the most
+significant bit is unpacked first from each byte. &nbsp;GL_TRUE
+indicates that the least significant bit is unpacked first from each
+byte. <br>
+      </td>
+      <td style="vertical-align: top;">GL_FALSE<br>
+      </td>
+    </tr>
+  </tbody>
+</table>
+<br>
+<br>
+The GL_UNPACK_ROW_LENGTH specifies the stride (in pixels) for advancing
+from one row of the image to the next.&nbsp; If it's zero, the <span
+ style="font-style: italic;">width</span> parameter to <span
+ style="font-weight: bold;">glBitmap</span> specifies the width of the
+image in memory.<br>
+<br>
+GL_UNPACK_LSB_FIRST determines whether the least significant or most
+significant bit in each byte is unpacked first. &nbsp;Unpacking occurs
+in left to right order (in image space).<br>
+<br>
+The value of bit (i, j) of the image (where i is the image row and j is
+the image column) is found as follows:<br>
+<br>
+<div style="margin-left: 40px;">rowLength = (GL_UNPACK_ROW_LENGTH != 0)
+? GL_UNPACK_ROW_LENGTH : <span style="font-style: italic;">width</span>;<br>
+<br>
+byte = <span style="font-style: italic;">image</span>[((rowLength + 7)
+/ 8) * i + j / 8];<br>
+<br>
+if (GL_UNPACK_LSB_FIRST != 0)<br>
+&nbsp;&nbsp;&nbsp; bitMask = 1 &lt;&lt; (j % 8);<br>
+else<br>
+&nbsp;&nbsp;&nbsp; bitMask = 128 &gt;&gt; (j % 8);<br>
+<br>
+if (byte &amp; bitMask)<br>
+&nbsp;&nbsp;&nbsp; bit = 1;<br>
+else<br>
+&nbsp;&nbsp;&nbsp; bit = 0;<br>
+<br>
+</div>
+<span style="font-style: italic;"><span style="font-style: italic;"></span></span>
+<h3>4.5.2 Rasterization</h3>
+If the current raster position is (x<sub>rp</sub>, y<sub>rp</sub>, z<sub>rp</sub>,
+w<sub>rp</sub>), then the bitmap is rasterized according to the
+following algorithm:<br>
+<br>
+for (j = 0; j &lt; <span style="font-style: italic;">height</span>;
+j++) {<br>
+&nbsp;&nbsp;&nbsp; for (i = 0; i &lt; <span style="font-style: italic;">width</span>;
+i++) {<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; if (bit(i,j)) {<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; fragment.x =
+floor(x<sub>rp</sub> - <span style="font-style: italic;">xOrig</span>)
++ i;<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; fragment.y =
+floor(y<sub>rp</sub> - <span style="font-style: italic;">yOrig</span>)
++ j;<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; fragment.color
+= GL_CURRENT_RASTER_COLOR;<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;
+fragment.texture = GL_CURRENT_RASTER_TEXTURE_COORDS;<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;
+ProcessFragment(fragment)<br>
+&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;}<br>
+&nbsp;&nbsp;&nbsp; }<br>
+}<br>
+<br>
+After the bitmap has been rendered the current raster position is
+updated as follows:<br>
+<br>
+<div style="margin-left: 40px;">x<sub>rp</sub> = x<sub>rp</sub> + <span
+ style="font-style: italic;">xMove</span><br>
+y<sub>rp</sub> = y<sub>rp</sub> + <span style="font-style: italic;">yMove</span><br>

+<h1>5. Texture Mapping<br>
+</h1>
+There are four elements to texture mapping: texture coordinate
+specification, texture image specification, texture sampling and texture
+application.<br>
+<br>
+Texture mapping is enabled and disabled with the commands <span
+ style="font-weight: bold;">glEnable</span>(GL_TEXTURE_2D) and <span
+ style="font-weight: bold;">glDisable</span>(GL_TEXTURE_2D).<br>
+<br>
+<h2>5.1 Texture Image Specification</h2>
+A texture image is specified with the command:<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glTexImage2D</span>(GLenum<span
+ style="font-style: italic;"> target</span>, GLint <span
+ style="font-style: italic;">level</span>, GLint <span
+ style="font-style: italic;">internalFormat,</span> GLsizei <span

+ style="font-style: italic;">format,</span> GLenum <span
+ style="font-style: italic;">type,</span> const GLvoid *<span
+ style="font-style: italic;">pixels</span> )<br>
+</div>
+<br>
+<span style="font-style: italic;">target</span> must be GL_TEXTURE_2D.
+&nbsp;<span style="font-style: italic;">level </span>indicates the
+mipmap level for mipmap textures. &nbsp;<span style="font-style: italic;">internalFormat</span>
+is a hint to indicate the preferred internal storage format for the
+texture. &nbsp;<span style="font-style: italic;">width</span> and <span
+ style="font-style: italic;">height </span>indicate the image size in
+pixels (or texels). &nbsp;<span style="font-style: italic;">border </span>must
+be zero. &nbsp;<span style="font-style: italic;">format</span> and <span
+ style="font-style: italic;">type</span> describe the pixel format and
+data type for the incoming image. &nbsp;<span style="font-style: italic;">pixels</span>
+points to the incoming texture image. &nbsp;These parameters are
+described in more detail below.<br>
+<br>
+<h3>5.1.1 Texture Image Size and Mipmaps</h3>
+<h3><span style="font-style: italic;"></span></h3>
+Texture images must have dimensions (width and height) that are powers
+of two. For example: 256 x 256, 32 x 1024, 1 x 8, etc. &nbsp;That is, it
+must be the case that <span style="font-style: italic;">width </span>=
+2<sup>n</sup> and <span style="font-style: italic;">height</span> = 2<sup>m</sup>
+for some positive integers n and m.<br>
+<br>
+Mipmapping is a method of antialiasing or filtering textures to improve
+their appearance. &nbsp;A mipmap is a set of images consisting of a base
+image and a set of filtered, reduced-resolution images. &nbsp;If the
+base image (<span style="font-style: italic;">level</span>=0) is of
+width 2<sup>n</sup> and height 2<sup>m</sup> then the level 1 image must
+be of width 2<sup>n-1</sup> and height 2<sup>m-1</sup>. &nbsp;Each mipmap
+level is half the width and height of the previous level, or at least
+one. &nbsp;The last mipmap level has a width and height of one.<br>
+<br>
+The following is an example of a mipmap's image levels:<br>

+If the <span style="font-style: italic;">width</span> or <span

+two, the error GL_INVALID_VALUE is raised. &nbsp;If the image levels in
+a mipmap do not satisfy the restrictions listed above the texture is
+considered to be <span style="font-style: italic;">inconsistent</span>
+and the system will behave as if the texturing is disabled.<br>
+<br>
+<h3>5.1.2 Texture Image Formats and Unpacking</h3>
+The <span style="font-weight: bold;">glTexImage2D</span> command's <span
+ style="font-style: italic;"><span style="font-weight: bold;"></span></span><span
+ style="font-style: italic;">format</span> and <span
+ style="font-style: italic;">type</span> parameters describe the format
+of the incoming texture image.&nbsp; Accepted values for <span
+ style="font-style: italic;">format</span> are GL_INTENSITY, GL_RGB and
+GL_RGBA. &nbsp;The <span style="font-style: italic;">type</span>
+parameter must be GL_UNSIGNED_BYTE. &nbsp;Pixel component values are
+thus in the range 0 through 255.<br>
+<br>
+If <span style="font-style: italic;">format</span> is GL_INTENSITY then
+the image has one byte per pixel which specifies the pixel's red, green,
+blue and alpha values.<span style="font-style: italic;"></span><br>
+<br>
+If <span style="font-style: italic;">format</span> is GL_RGB then the
+image has three bytes per pixel which specify the pixel's red, green and
+blue values (in that order). &nbsp;The alpha value defaults to 255.<br>
+<br>
+If <span style="font-style: italic;">format</span> is GL_RGBA then the
+image has four bytes per pixel which specify the pixel's red, green,
+blue and alpha values (in that order).<br>
+<br>
+The command<br>
+<br>
+<div style="margin-left: 40px;">void<span style="font-weight: bold;">
+glPixelStorei</span>(GLenum <span style="font-style: italic;">pname</span>,
+GLint <span style="font-style: italic;">value</span>)<br>
+</div>
+<br>
+controls the unpacking of texture image data from client memory. &nbsp;<span
+ style="font-style: italic;">pname</span> may be GL_UNPACK_ROW_LENGTH to
+indicate the stride, in pixels, between subsequent rows of the image in
+client memory. &nbsp;If GL_UNPACK_ROW_LENGTH is zero (the default) then
+the <span style="font-style: italic;">width</span> parameter to <span
+ style="font-weight: bold;">glTexImage2D </span>determines the stride.<span
+ style="font-style: italic;"></span><br>
+<br>
+<h3>5.1.3 Internal Texture Format</h3>
+<span style="font-weight: bold;">glTexImage2D<span
+ style="font-style: italic;"> </span></span>converts the incoming
+texture image to one of the supported internal texture formats.<br>
+<br>
+The <span style="font-style: italic;">internalFormat</span> parameter
+indicates the desired internal format for the texture and may be either
+GL_INTENSITY8, GL_RGB5 or GL_RGBA8.<br>
+<br>
+If <span style="font-style: italic;">internalFormat</span> is
+GL_INTENSITY8 then the texture has one byte per texel (texture element)
+which indicates the texel's intensity (or brightness). &nbsp;The
+intensity is obtained from the incoming image's red channel.<br>
+<br>
+If <span style="font-style: italic;">internalFormat</span> is GL_RGB5
+then the texture is stored with two bytes per texel: &nbsp;5 bits per
+red value, 5 bits per green value and 5 bits per blue value.<br>
+<br>
+If <span style="font-style: italic;">internalFormat </span>is
+GL_RGBA8 then the texture is stored with four bytes per texel: &nbsp;8
+bits for each of the red, green, &nbsp;blue and alpha values.<br>
+<br>
+The internal format is also significant to texture application (see
+section 5.4).<br>
+<br>
+<h2>5.2 Texture Coordinates</h2>
+Texture coordinates control the mapping from local polygon space to
+texture image space. &nbsp;Texture coordinates are set for each vertex
+with the <span style="font-weight: bold;">glTexCoord</span> commands.
+&nbsp;During line and polygon rasterization the vertex's texture
+coordinates are interpolated across the primitive to produce a texture
+coordinate for each fragment. &nbsp;The fragment texture coordinates are
+used to sample the current texture image.<br>
+<br>
+Texture coordinates are normally in the range [0, 1]. &nbsp;Values
+outside that range are processed according to the <span
+ style="font-style: italic;">texture wrap mode</span>. &nbsp;The
+texture wrap mode is set with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glTexParameteri</span>(GLenum<span
+ style="font-style: italic;"> target</span>, GLenum <span
+ style="font-style: italic;">pname</span>, GLint <span
+ style="font-style: italic;">value</span>)<br>
+<br>
+</div>
+<span style="font-style: italic;">target</span> must be GL_TEXTURE_2D.
+&nbsp;If <span style="font-style: italic;">pname</span> is
+GL_TEXTURE_WRAP_S or GL_TEXTURE_WRAP_T then <span
+ style="font-style: italic;">value</span> must be either
+GL_CLAMP_TO_EDGE or GL_REPEAT.<br>
+<br>
+For GL_CLAMP_TO_EDGE, texture coordinates are effectively clamped to
+the interval [0, 1].<br>
+<br>
+For GL_REPEAT, the integer part of texture coordinates is ignored; only
+the fractional part of the texture coordinates is used. &nbsp;This
+allows texture images to repeated or tiled across an object.<br>
+<br>
+<h2>5.3 Texture Sampling</h2>
+Texture sampling is the process of using texture coordinates to extract
+a color from the texture image. &nbsp;Multiple, weighted samples may be
+taken from the texture and combined during the filtering step.<br>
+<br>
+During texture coordinate interpolation a <span
+ style="font-style: italic;">level of detail</span> value (lambda) is
+computed for each fragment. &nbsp;For a mipmapped texture, lambda
+determines which level (or levels) of the mipmap will be sampled to
+obtain the texture color.<br>
+<br>
+If lambda indicates that multiple texels map to a single screen pixel,
+then the texture <span style="font-style: italic;">minification</span>

+<h3>5.3.1 Texture Minification</h3>
+The texture minification filter is set with the <span
+ style="font-weight: bold;">glTexParameteri </span><span
+ style="font-style: italic;"></span><span style="font-weight: bold;"></span><span
+ style="font-style: italic;"></span> command by setting <span
+ style="font-style: italic;">target</span> to GL_TEXTURE_2D, setting <span
+ style="font-style: italic;">pname</span> to GL_TEXTURE_MIN_FILTER and
+setting <span style="font-style: italic;">value</span> to GL_NEAREST,
+GL_LINEAR, GL_NEAREST_MIPMAP_NEAREST,&nbsp;
+GL_NEAREST_MIPMAP_LINEAR,&nbsp; &nbsp;GL_LINEAR_MIPMAP_NEAREST or
+GL_LINEAR_MIPMAP_LINEAR.<br>
+<br>
+GL_NEAREST samples the texel nearest the texture coordinate in the
+level 0 texture image.<br>
+<br>
+GL_LINEAR samples the four texels around the texture coordinate in the
+level 0 texture image. &nbsp;The four texels are linearly weighted to
+compute the final texel value.<br>
+<br>
+GL_NEAREST_MIPMAP_NEAREST samples the texel nearest the texture
+coordinate in the level N texture image. &nbsp;N is the level of detail
+and is computed by the partial derivatives of the texture coordinates
+with respect to the window coordinates.<br>
+<br>
+GL_NEAREST_MIPMAP_LINEAR samples two texels nearest the texture
+coordinates in the level N and N+1 texture images. &nbsp;The two texels
+are linearly weighted to compute the final texel value. &nbsp;N is the
+level of detail and is computed by the partial derivatives of the
+texture coordinates with respect to the window coordinates.<br>
+<br>
+GL_LINEAR_MIPMAP_NEAREST samples four texels around the texture
+coordinate in the level N texture image. &nbsp;The four texels are
+linearly weighted to compute the final texel value. &nbsp;N is the level
+of detail and is computed by the partial derivatives of the texture
+coordinates with respect to the window coordinates.<br>
+<br>
+GL_LINEAR_MIPMAP_LINEAR samples four texels around the texture
+coordinate in the level N texture image and four texels around the
+texture coordinate in the level N+1 texture image. &nbsp;The eight
+texels are linearly weighted to compute the final texel value. &nbsp;N
+is the level of detail and is computed by the partial derivatives of the
+texture coordinates with respect to the window coordinates.<br>
+<br>
+Filter modes other than GL_LINEAR and GL_NEAREST requires that the
+texture have a complete set of mipmaps. &nbsp;If the mipmap is
+incomplete, it is as if texturing is disabled.<br>
+&nbsp;<br>
+<h3>5.3.2 Texture Magnification</h3>
+The texture magnification filter is set with the <span
+ style="font-weight: bold;">glTexParameteri </span><span
+ style="font-style: italic;"></span><span style="font-weight: bold;"></span>command
+by setting <span style="font-style: italic;">target</span> to

+GL_TEXTURE_MAG_FILTER and setting <span style="font-style: italic;">value</span>
+to GL_NEAREST or GL_LINEAR.<br>
+<br>
+GL_NEAREST samples the texel nearest the texture coordinate in the
+level 0 texture image.<br>
+<br>
+GL_LINEAR samples the four texels around the texture coordinate in the
+level 0 texture image. &nbsp;The four texels are linearly weighted to
+compute the final texel value.<br>
+<br>
+<h2>5.4 Texture Application</h2>
+The sampled texture value is combined with the incoming fragment color
+to produce a new fragment color. &nbsp;The fragment and texture colors
+are combined according to the texture environment mode and the current
+texture's base internal format. &nbsp;The texture environment mode is
+set with the command<br>
+<br>
+<div style="margin-left: 40px;">void<span style="font-weight: bold;">
+glTexEnvi</span>(GLenum <span style="font-style: italic;">target</span>,
+GLenum <span style="font-style: italic;">pname</span>, GLint <span
+ style="font-style: italic;">value</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">target</span> must be GL_TEXTURE_ENV.
+&nbsp;If <span style="font-style: italic;">pname</span> is
+GL_TEXTURE_ENV_MODE then <span style="font-style: italic;">value</span>
+must be one of GL_REPLACE, GL_MODULATE, GL_DECAL, or GL_BLEND.<br>
+<br>
+There is also a <span style="font-style: italic;">texture environment
+color</span> that can factor into texture application. &nbsp;The texture
+environment color can be set with the command<br>
+<br>
+<div style="margin-left: 40px;">void<span style="font-weight: bold;">
+glTexEnvfv</span>(GLenum <span style="font-style: italic;">target</span>,
+GLenum <span style="font-style: italic;">pname</span>, const GLfloat *<span

+</div>
+<span style="font-style: italic;"></span><br>
+<span style="font-style: italic;">target</span> must be GL_TEXTURE_ENV.
+&nbsp;If <span style="font-style: italic;">pname</span> is
+GL_TEXTURE_ENV_COLOR then <span style="font-style: italic;">value </span>must
+point to an array of four values which specify the red, green, blue,
+and alpha values of the texture environment color. &nbsp;The values are
+clamped to the range [0, 1]. &nbsp;The default color is (0, 0, 0, 0).<br>
+<span style="font-style: italic;"></span><br>
+The following table describes the arithmetic used for each combination
+of environment mode and base internal format. &nbsp;(Rf, Gf, Bf, Af) is
+the incoming fragment color. &nbsp;(Rt, Gt, Bt, At) is the sampled
+texture color. &nbsp;Lt is the sampled texture luminance. &nbsp;<span
+ style="font-style: italic;"></span>'It' is the sampled texture
+intensity. &nbsp;(Rc, Gc, Bc, Ac) is the texture environment color.
+&nbsp;(Rv, Gv, Bv, Av) is the resulting value.<br>

+<h2>5.5 Texture Objects</h2>
+Texture objects encapsulate a set of texture images (mipmap) and
+related state into a named object. &nbsp;This facilitates use of
+multiple textures in an application. &nbsp;Texture objects are named
+with GLuints (unsigned integers). &nbsp;There is a default texture
+object with the name/identifier zero which can never be deleted.<br>
+<br>
+<h3>5.5.1 Creating Texture Objects</h3>
+A texture object is created by binding a new GLuint identifier to the
+GL_TEXTURE_2D target with the command:<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glBindTexture</span>(GLenum<span
+ style="font-style: italic;"> target</span>, GLuint <span
+ style="font-style: italic;">textureID</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">target</span> must be GL_TEXTURE_2D.
+&nbsp;<span style="font-style: italic;">textureID</span> may be any
+unsigned integer. &nbsp;If <span style="font-style: italic;">textureID</span>
+does not name an existing texture object, a new texture object with that
+ID will be created, initialized to the default state. &nbsp;Whether the
+ID is new or existed previously, that named texture object is bound as
+the <span style="font-style: italic;">current texture object</span>.
+&nbsp;Subsequent <span style="font-weight: bold;">glTexParameter </span>and<span
+ style="font-weight: bold;">glTexImage2D<span
+ style="font-style: italic;"> </span></span>calls will effect the
+current texture object.<br>
+<span style="font-style: italic;"></span><span
+ style="font-weight: bold;"><span style="font-style: italic;"> </span></span><br>
+<h3>5.5.2 Deleting Texture Objects</h3>
+One or more texture objects may be deleted with the command:<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glDeleteTextures</span>(GLsizei<span
+ style="font-style: italic;">n</span>, const GLuint *<span
+ style="font-style: italic;">textureIDs</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">textureIDs</span> is an array of <span
+ style="font-style: italic;">n</span> texture IDs. &nbsp;The named
+texture objects will be deleted. &nbsp;If the current texture object is
+deleted the default texture object (number 0) will be bound as the
+current texture object.<br>
+<br>
+<h3>5.5.3 Allocating Texture Object Identifiers</h3>
+A list of new, unused texture IDs can be obtained by calling the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glGenTextures</span>(GLsizei<span
+ style="font-style: italic;"> n</span>, GLuint *<span
+ style="font-style: italic;">textureIDs</span>)<br>
+</div>
+<br>
+An array of <span style="font-style: italic;">n</span> unused texture
+IDs will be returned in the <span style="font-style: italic;">textureIDs</span>
+array.<br>
+<br>
+<br>
+<h1>6. Per-fragment Operations</h1>
+The fragments produced by rasterization are subjected to a number of
+operations which either modify the fragment or test the fragment
+(discarding the fragment if the test fails.) &nbsp;This chapter
+describes the per-fragment operations. &nbsp;They are presented in the
+order in which they're performed. &nbsp;If a fragment fails a test it is
+discarded and not subjected to subsequent tests or modifications.<br>
+<br>
+<h2>6.1 Scissor Test</h2>
+The scissor test limits rendering to a 2-D rectangular region of the
+framebuffer. &nbsp;The command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glScissor</span>(GLint<span
+ style="font-style: italic;">x</span>, GLint <span
+ style="font-style: italic;">y</span>, GLsizei <span
+ style="font-style: italic;">width</span>, GLsizei<span
+ style="font-style: italic;"> height</span>)<br>
+</div>
+<br>
+defines a clipping region with the lower-left corner at (<span
+ style="font-style: italic;">x, y</span>) and the given <span
+ style="font-style: italic;">width</span> and <span
+ style="font-style: italic;">height</span>. &nbsp;The scissor test is
+enabled and disabled with the command <span style="font-weight: bold;">glEnable</span>(GL_SCISSOR_TEST)
+and <span style="font-weight: bold;">glDisable</span>(GL_SCISSOR_TEST).<br>
+<br>
+If the incoming fragment's position is (x<sub>f</sub>, y<sub>f</sub>)
+then the fragment will pass the test if <span
+ style="font-style: italic;">x</span> &lt;= x<sub>f</sub> &lt; <span
+ style="font-style: italic;">x</span> + <span
+ style="font-style: italic;">width</span> and <span
+ style="font-style: italic;">y</span> &lt;= y<sub>f</sub> &lt; <span
+ style="font-style: italic;">y</span> + <span
+ style="font-style: italic;">height. &nbsp;</span>Otherwise, the
+fragment is discarded.<br>
+<br>
+If <span style="font-style: italic;">width</span> or <span
+ style="font-style: italic;">height</span> is less than zero the error
+GL_INVALID_VALUE is raised. &nbsp;The default scissor rectangle bounds
+are (0, 0, w, h) where w is the initial window width and h is the
+initial window height. &nbsp;The scissor test is disabled by default.<br>
+<br>
+<h2>6.2 Alpha Test</h2>
+The alpha test compares the fragment's alpha value against a reference
+value and discards the fragment if the comparison fails. &nbsp;The test
+is specified by the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glAlphaFunc</span>(GLenum<span
+ style="font-style: italic;">mode</span>, GLclampf <span
+ style="font-style: italic;">reference</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">mode</span> specifies an inequality
+and <span style="font-style: italic;">reference</span> specifies a value
+to compare against. &nbsp;The following table lists all possible
+modes&nbsp;<span style="font-style: italic;"></span>and the
+corresponding test:<br>

+<br>
+The <span style="font-style: italic;">reference</span> parameter is

+<br>
+The alpha test is enabled and disabled with the commands <span
+ style="font-weight: bold;">glEnable</span>(GL_ALPHA_TEST) and <span
+ style="font-weight: bold;">glDisable</span>(GL_ALPHA_TEST).<br>
+<br>
+The default mode is GL_ALWAYS and the default reference value is 0.<br>
+<br>
+<h2>6.3 Stencil Test</h2>
+The stencil buffer stores an N-bit integer value for each pixel in the
+frame buffer. &nbsp;The stencil test compares the stencil buffer value
+at the fragment's position to a reference value and possibly discards
+the fragment based on the outcome. &nbsp;Furthermore, the stencil buffer
+value may be updated or modified depending on the outcome. &nbsp;If
+there is no stencil buffer the stencil test is bypassed.<br>
+<br>
+Stenciling is controlled by the commands<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glStencilFunc</span>(GLenum<span

+<h1>7. Frame Buffer Operations</h1>
+The frame buffer is considered to be a two-dimensional array of pixels.
+&nbsp;The frame buffer is also organized into layers or logical buffers.
+&nbsp;There may be a front color buffer, back color buffer and stencil
+buffer. &nbsp;A double-buffered frame buffer has both a front color
+buffer and back color buffer. &nbsp;A single-buffered framebuffer only
+has a front color buffer. &nbsp;Each pixel in a color buffer has a red,
+green and blue value and an optional alpha value.<br>
+<br>
+<h2>7.1 Clearing Buffers</h2>
+Buffers are cleared (set to uniform values) with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glClear</span>(GLbitfield<span
+ style="font-style: italic;">buffers</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">buffers</span> is a bitmask for which
+the value may be the bitwise-OR of the values GL_COLOR_BUFFER_BIT and
+GL_STENCIL_BUFFER_BIT. &nbsp;If the GL_COLOR_BUFFER_BIT bit is
+specified, the current color buffer will be cleared. &nbsp;If the
+GL_STENCIL_BUFFER_BIT bit is specified, the stencil buffer will be
+cleared.<br>
+<br>
+The current color buffer is specified with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glDrawBuffer</span>(GLenum<span
+ style="font-style: italic;"> buffer</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">buffer</span> may be either GL_FRONT,
+GL_BACK or GL_NONE. &nbsp;GL_FRONT indicates that the front color buffer
+will be modified by <span style="font-weight: bold;">glClear</span> and
+any drawing command. &nbsp;GL_BACK indicates that the back color buffer
+will be modified by <span style="font-weight: bold;">glClear</span> and
+any drawing command. &nbsp;GL_NONE indicates that neither color buffer
+will be modified by <span style="font-weight: bold;">glClear</span> or
+any drawing command. &nbsp;GL_BACK is only valid for double-buffered
+frame buffers.<br>
+<br>
+The current scissor rectangle, set by the <span
+ style="font-weight: bold;">glScissor</span> command, effects <span
+ style="font-weight: bold;">glClear</span><span
+ style="font-style: italic;">,</span><span style="font-style: italic;"> </span>limiting
+the clear to the scissor rectangle, if it's enabled. &nbsp;Furthermore, <span
+ style="font-weight: bold;"></span>only the color channels enabled by <span
+ style="font-weight: bold;">glColorMask</span> will be effected by <span
+ style="font-weight: bold;">glClear</span>(GL_COLOR_BUFFER_BIT).
+&nbsp;Likewise, only the stencil bits enabled by <span
+ style="font-weight: bold;">glStencilMask</span> will be effected by <span
+ style="font-weight: bold;">glClear</span>(GL_STENCIL_BUFFER_BIT).<br>
+<br>
+The current clear color is set with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glClearColor</span>(GLclampf<span
+ style="font-style: italic;">red</span>, GLclampf <span

+ style="font-style: italic;">blue</span>, GLclampf <span
+ style="font-style: italic;">alpha</span>)<br>
+</div>
+<br>
+Subsequent calls to <span style="font-weight: bold;">glClear</span>
+will use the color (<span style="font-style: italic;">red, green, blue,
+alpha</span>) to clear the front or back color buffers.<br>
+<span style="font-style: italic;"></span><br>
+The current stencil clear value is set with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glClearStencil</span>(GLint<span
+ style="font-style: italic;">clearValue</span>)<br>
+</div>
+<br>
+If the stencil buffer is N bits deep, the least significant N bits of <span
+ style="font-style: italic;">clearValue</span> will be used to clear the
+stencil buffer.<br>

+<h1>8. Other Features</h1>
+<h2>8.1 Frame Buffer Readback</h2>
+A rectangular region of pixels can be read from the frame buffer and
+placed in client memory with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glReadPixels</span>(GLint<span
+ style="font-style: italic;">x</span>, GLint <span

+ style="font-style: italic;">data</span>)<br>
+</div>
+<br>
+<span style="font-style: italic;">x</span> and <span
+ style="font-style: italic;">y</span> specify the coordinate of the
+lower-left corner of the region to read and <span
+ style="font-style: italic;">width</span> and <span
+ style="font-style: italic;">height</span> specify the size of the
+rectangular region to read. &nbsp;<span style="font-style: italic;">format</span>
+specifies the format of image data and must be either GL_RGB or
+GL_RGBA.&nbsp; <span style="font-style: italic;">type</span> specify the
+data type of the image data and must be either GL_UNSIGNED_BYTE or
+GL_FLOAT. &nbsp;Other values for <span style="font-style: italic;">format</span>
+or <span style="font-style: italic;">type</span> will cause the error
+GL_INVALID_ENUM to be raised.<br>
+<br>
+The framebuffer may contain 3-component colors (red, green, blue) or
+4-component colors (red, green, blue, alpha). &nbsp;If an alpha channel
+is not present, alpha values default to 1.0.<br>
+<br>
+The frame buffer color components (red, green, blue, alpha) are either
+converted to 8-bit unsigned integers in the range[0, 255] if <span
+ style="font-style: italic;">type </span>is GL_UNSIGNED_BYTE or
+converted to floating point values in the range [0, 1] if <span
+ style="font-style: italic;">type</span> is GL_FLOAT. &nbsp;The (red,
+green, blue, alpha) tuples are then stored as GL_RGB triplets (by
+dropping the alpha component) or GL_RGBA quadruples in client memory.<br>
+<br>
+Image data is <span style="font-style: italic;">packed</span> into
+client memory according to the pixel packing parameters which are set by
+the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glPixelStorei</span>(GLenum<span

+The function FrameBuffer(<span style="font-style: italic;">c, r</span>)
+returns the pixel in the frame buffer at column <span
+ style="font-style: italic;">c</span> of row <span
+ style="font-style: italic;">r. &nbsp;</span><span
+ style="font-style: italic;">data</span> is considered to be either a
+GLubyte pointer or a GLfloat pointer, depending on the <span
+ style="font-style: italic;">type</span> parameter. &nbsp;Similarly, the
+FrameBuffer function returns either GLubyte values in the range [0, 255]
+or GLfloat values in the range [0,1], depending on the <span
+ style="font-style: italic;">type</span> parameter.<br>
+<br>
+Pixels may be read from either the front or back color buffer.
+&nbsp;The command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glReadBuffer</span>(GLenum<span
+ style="font-style: italic;">buffer</span>)<br>
+</div>
+<br>
+specifies the source for reading images with <span
+ style="font-weight: bold;">glReadPixels</span>. &nbsp;If <span
+ style="font-style: italic;">buffer</span> is GL_FRONT then front color
+buffer is the source. &nbsp;If <span style="font-style: italic;">buffer</span>
+is GL_BACK then the back color buffer is the source. &nbsp;It is illegal
+to specify GL_BACK when the color buffer is not double buffered.
+&nbsp;Any invalid value for <span style="font-style: italic;">buffer</span>
+will raise the error GL_INVALID_ENUM.<br>
+<br>
+The default read source is GL_BACK if the frame buffer is double
+buffered. &nbsp;Otherwise, the default read source is GL_FRONT.<br>
+<br>
+<h2>8.2 Selection Mode</h2>
+Selection mode is typically used to implement <span
+ style="font-style: italic;">picking</span>: determining which
+primitive(s) are present at particular window positions. &nbsp;The
+command<br>
+<br>
+<div style="margin-left: 40px;">GLint <span style="font-weight: bold;">glRenderMode</span>(GLenum<span
+ style="font-style: italic;">mode</span>)<br>
+</div>
+<br>
+is used to enable selection mode. &nbsp;If <span
+ style="font-style: italic;">mode</span> is GL_SELECTION the graphics
+library is put into selection mode. &nbsp;If <span
+ style="font-style: italic;">mode</span> is GL_RENDER the graphic
+library is put into normal rendering mode. &nbsp;Any other value for <span
+ style="font-style: italic;">mode</span> will raise the error
+GL_INVALID_ENUM.<br>
+<br>
+When in selection mode rendering commands will not effect the
+framebuffer. &nbsp;Instead, a record of the primitives that would have
+been drawn is placed in the <span style="font-style: italic;">selection</span> <span
+ style="font-style: italic;">buffer</span>. &nbsp;The selection buffer
+is specified with the command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glSelectionBuffer</span>(GLsizei<span
+ style="font-style: italic;">n</span>, GLuint *<span
+ style="font-style: italic;">buffer</span>)<br>
+</div>
+<span style="font-style: italic;"></span><span
+ style="font-style: italic;"><br>
+buffer</span> is an array of <span style="font-style: italic;">n</span>
+unsigned integers. &nbsp;No more than <span style="font-style: italic;">n</span>
+values will be placed in the buffer.<br>
+<br>
+The <span style="font-style: italic;">name stack</span> is a stack
+(LIFO) of unsigned integer names. &nbsp;The following commands
+manipulate the name stack:<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glInitNames</span>(void)<br>
+void <span style="font-weight: bold;">glPushName</span>(GLuint <span
+ style="font-style: italic;">name</span>)<br>
+void <span style="font-weight: bold;">glPopName</span>(void)<br>
+void <span style="font-weight: bold;">glLoadName</span>(GLuint <span
+ style="font-style: italic;">name</span>)<br>
+</div>
+<br>
+<span style="font-weight: bold;">glInitNames</span> resets the name
+stack to an empty state. &nbsp;<span style="font-weight: bold;">glPushName<span
+ style="font-style: italic;"> </span></span>pushes the given <span
+ style="font-style: italic;">name</span> value onto the stack. &nbsp;<span
+ style="font-weight: bold;">glPopName</span> pops the top name from the
+stack. &nbsp;<span style="font-weight: bold;">glLoadName<span
+ style="font-style: italic;"> </span></span>replaces the top value on
+the stack with the specified <span style="font-style: italic;">name</span>.
+&nbsp;Stack underflow and overflow conditions cause the errors
+GL_STACK_OVERFLOW and GL_STACK_UNDERFLOW to be raised.<br>
+<br>
+While in selection mode, primitives (points, lines, polygons) are
+transformed and clip-tested normally. &nbsp;Primitives which aren't
+discarded by clipping cause the <span style="font-style: italic;">hit</span> <span
+ style="font-style: italic;">data</span> to be updated. &nbsp;The hit
+data consists of three pieces of information: a hit flag, a minimum Z
+value and a maximum Z value. &nbsp;First, the hit flag is set.
+&nbsp;Then, for each of the primitive's vertices, the vertex Z value is
+compared to the minimum and maximum Z values. &nbsp;The minimum Z value
+is updated if the vertex's Z value is less than the minimum Z value.
+&nbsp;The maximum Z value is updated if the vertex's Z value is greater
+than the maximum Z value.<br>
+<br>
+When any of <span style="font-weight: bold;">glInitNames</span><span
+ style="font-style: italic;"><span style="font-style: italic;">, </span></span><span
+ style="font-weight: bold;">glPushName</span>, <span
+ style="font-weight: bold;">glPopName</span>, <span
+ style="font-weight: bold;">glLoadName</span> or <span
+ style="font-weight: bold;">glRenderMode</span> are called and the hit
+flag is set, a <span style="font-style: italic;">hit record</span> is
+written to the selection buffer.<br>
+<br>
+A hit record consists of a sequence of unsigned integers. &nbsp;The
+first value is the size of the name stack. &nbsp;The second value is the
+minimum Z value multiplied by 2<sup>32</sup>-1. &nbsp;The third value is
+the maximum Z value multiplied by 2<sup>32</sup>-1. &nbsp;The remaining
+values are the values in the name stack, in bottom to top order.
+&nbsp;The hit flag is cleared after a hit record is written to the
+selection buffer. &nbsp;Hit records are places sequentially into the
+selection buffer until it is full or selection mode is terminated.<br>
+<br>
+Selection mode is terminated by calling <span
+ style="font-weight: bold;">glRenderMode</span>(GL_RENDER). &nbsp; The
+return value of <span style="font-weight: bold;">glRenderMode</span>
+will be -1 if the selection buffer overflowed. &nbsp;Otherwise, the
+return value will indicate the number of values written into the
+selection buffer.<br>
+<br>
+<h2>8.3 Synchronization</h2>
+The command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glFlush</span>(void)<br>
+</div>
+<br>
+makes the graphics library to flush all pending graphics commands.
+&nbsp;The command<br>
+<div style="margin-left: 40px;"><br>
+void <span style="font-weight: bold;">glFinish</span>(void)<br>
+</div>
+<br>
+makes the graphics library flush the command queue and wait until those
+commands are completed. &nbsp;<span style="font-weight: bold;">glFlush</span>
+will not return until all previous graphics commands have been fully
+completed.<br>
+<br>
+These commands are typically used to force completion of rendering to
+the front color buffer. &nbsp;Otherwise, rendering to the front color
+buffer may not appear. &nbsp;The <span style="font-style: italic;">swapbuffers</span>
+command (part of the window system binding library) does an implicit
+flush before swapping the front and back color buffers. &nbsp;The <span
+ style="font-weight: bold;">glReadPixels</span> command also does an
+implicit flush before reading pixel data from the frame buffer.<br>
+<br>
+<h1>9. State Queries</h1>
+The current value of nearly all library state variables can be queried.
+&nbsp;This chapter describes the commands used for querying the value of
+state variables.<br>
+<br>
+<h2>9.1 General State Queries</h2>
+The command<br>
+<br>
+<div style="margin-left: 40px;">void <span style="font-weight: bold;">glGetFloatv</span>(GLenum<span
+ style="font-style: italic;">pname</span>, GLfloat *<span
+ style="font-style: italic;">values</span>)<br>
+</div>
+<br>
+returns the value(s) of the state variable specified by <span
+ style="font-style: italic;">pname</span>. &nbsp;The following table
+lists all accepted values for <span style="font-style: italic;">pname</span>
+and a description of the value(s). &nbsp;Specifying any other value for <span

+<h2>10.18 Imaging Subset</h2>
+The OpenGL imaging subset (which implements features such as
+convolution, histogram, min/max recording, color matrix and color
+tables) is not supported.<br>
+<br>
+<br>
+<h1>Appendix A: Issues</h1>
+This appendix lists documentation and subset issues with their current
+status. &nbsp;For items which are still open, the documentation (above)
+follows the recommended solution.<br>
+<br>
+<h2>A.1 Vertex Arrays</h2>
+Should vertex arrays be supported? &nbsp;Is there a performance
+advantage?<br>
+<br>
+RESOLUTION: No, there isn't enough of a performance advantage to
+justify them.<br>
+<br>
+<h2>A.2 Polygon Antialiasing and Edge Flags</h2>
+Should edge flags be supported for antialiasing?<br>
+<br>
+Edge flags don't effect antialiasing, at least not normally. &nbsp;A
+number of approaches to antialiasing have been summarized in email.<br>
+<br>
+RECOMMENDATION: don't support edge flags. &nbsp;They don't effect
+polygon antialiasing.<br>
+<br>
+RESOLUTION: closed, as of 26 Feb 2003.<br>
+<br>
+<h2>A.3 glRasterPos vs. glWindowPos</h2>
+Should glRasterPos and/or glWindowPos commands be supported?<br>
+<br>
+RESOLUTION: Closed: implement glRasterPos commands, but not glWindowPos
+commands.<br>
+<br>
+<h2>A.4 GL_IBM_rasterpos_clip extension</h2>
+Should the GL_IBM_rasterpos_clip extension be implemented?<br>
+<br>
+RESOLUTION: &nbsp;No. &nbsp;It's not required.<br>
+<br>
+<h2>A.5 Image Formats and Types</h2>
+Which image formats and types should be supported for <span
+ style="font-weight: bold;">glTexImage2D</span> and <span
+ style="font-weight: bold;">glReadPixels</span>?<br>
+<br>
+OpenGL specifies a <span style="font-weight: bold;">large</span>
+variety of image formats and data types. &nbsp;Only a few are commonly
+used.<br>
+<br>
+RECOMMENDATION: &nbsp;we propose a subset:<br>
+<br>
+For <span style="font-weight: bold;">glTexImage2D</span> only allow <span
+ style="font-style: italic;">type</span>=GL_UNSIGNED_BYTE and <span
+ style="font-style: italic;">format</span>=GL_RGBA, GL_RGB,
+GL_INTENSITY. &nbsp; Only allow <span style="font-style: italic;">internalFormat</span>
+to be GL_RGBA, GL_RGB or GL_INTENSITY as well.&nbsp; Basically, only
+support image formats/types that are directly supported by the Radeon
+hardware. &nbsp;This will allow <span style="font-weight: bold;">glTexImage2D</span>
+to basically just use <span style="font-weight: bold;">memcpy</span> to
+copy texture images.<br>
+<br>
+For <span style="font-weight: bold;">glReadPixels</span>, only allow <span
+ style="font-style: italic;">type</span> = GL_UNSIGNED_BYTE or GL_FLOAT.
+&nbsp;Only allow <span style="font-style: italic;">format</span> =
+GL_RGB or GL_RGBA. &nbsp;This is just enough to support the OpenGL
+conformance tests.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.6 Texture Environment Modes</h2>
+Which texture environment modes should be supported? &nbsp;OpenGL 1.2
+has GL_REPLACE, GL_MODULATE, GL_DECAL and GL_BLEND. &nbsp;GL_DECAL isn't
+defined for all base internal texture formats. &nbsp;GL_ADD is another
+useful mode. &nbsp;Perhaps drop GL_DECAL mode and add GL_ADD mode.<br>
+<br>
+RECOMMENDATION: implement the standard modes GL_REPLACE, GL_MODULATE,
+GL_DECAL and GL_BLEND.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.7 Truncated Mipmaps and LOD Control</h2>
+Should we support the GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_MAX_LEVEL,
+GL_TEXTURE_MIN_LOD and GL_TEXTURE_MAX_LOD texture parameters?<br>
+<br>
+RECOMMENDATION: &nbsp;We propose omitting these features at this time,
+in the interest of simplifying the driver.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.8 Texture Priorities and Residency</h2>
+Should the subset support texture priorities via <span
+ style="font-weight: bold;">glPrioritizeTextures</span> and the <span
+ style="font-weight: bold;">glAreTexturesResident</span> command?<br>
+<br>
+RECOMMENDATION: &nbsp;Few applications use these features and
+functions. &nbsp;We propose omitting them to simplify the driver.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.9 Pixel Pack/Unpack Alignment Control</h2>
+Should we support the GL_PACK_ALIGNMENT and GL_UNPACK_ALIGNMENT options?<br>
+<br>
+These are used to align pixel data addresses to 1, 2 and 4-byte
+multiples for <span style="font-weight: bold;">glBitmap, glTexImage2D</span>
+and <span style="font-weight: bold;">glReadPixels</span>. &nbsp;These
+aren't strictly needed since the user can provide a 1, 2 or 4-byte
+aligned address and appropriate GL_PACK_ROW_LENGTH or
+GL_UNPACK_ROW_LENGTH values instead.<br>
+<br>
+RECOMMENDATION: &nbsp;We recommend omitting them to simplify the driver.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.10 Pixel Pack/Unpack Skip Rows/Pixels Control</h2>
+Should we support the GL_UNPACK_SKIP_PIXELS, GL_UNPACK_SKIP_ROWS,
+GL_PACK_SKIP_PIXELS and GL_PACK_SKIP_ROWS options for pixel
+unpacking/packing?<br>
+<br>
+These options aren't really needed since the user can adjust the start
+address and GL_PACK/UNPACK_ROW_LENGTH parameters to achieve the same
+effect.<br>
+<br>
+RECOMMENDATION: &nbsp;omit these parameters.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.11 Texture State Queries</h2>
+Should we support the command <span style="font-weight: bold;">glGetTexEnvi/fv,
+glGetTexParameteri/fv</span> and <span style="font-weight: bold;">glGetTexLevelParameteri/fv</span>?<br>
+<br>
+RECOMMENDATION: &nbsp;No.&nbsp;They're seldom needed and their
+implementation is several hundred lines of code in length.<br>
+<br>
+RESOLUTION: &nbsp;open<br>
+<br>
+<h2>A.12 glGetIntegerv, glGetBooleanv and glGetDoublev</h2>
+Should we support the commands <span style="font-weight: bold;">glGetIntegerv,
+glGetBooleanv </span>and <span style="font-weight: bold;">glGetDoublev</span>
+in addition to <span style="font-weight: bold;">glGetFloatv</span>?<br>
+<br>
+RECOMMENDATION: &nbsp;Omit the boolean, integer and double-valued
+functions. All state values which can be queried by these commands can
+be expressed as floating point values and queried with <span
+ style="font-weight: bold;">glGetFloatv</span>. &nbsp;The
+implementation of the other three commands involves many lines of code.<br>
+<br>
+RESOLUTION: &nbsp;open<br>
+<br>
+<h2>A.13 glBitmap and Per-Fragment Operations</h2>
+Should bitmaps rendered with <span style="font-weight: bold;">glBitmap</span>
+be subjected to the per-fragment operations?<br>
+<br>
+If bitmaps are implemented with points it will be easy to implement the
+per-fragment operations. &nbsp;Otherwise, it could be difficult.<br>
+<br>
+RECOMMENDATION: &nbsp;Implement glBitmap by drawing points/pixels with
+the hardware. &nbsp;This will make supporting the per-fragments
+trivially easy. &nbsp;Also, it makes portrait-mode display relatively
+easy.<br>
+<br>
+RESOLUTION: &nbsp;open<br>
+<br>
+<h2>A.14 Reduced gl.h Header File</h2>
+Should we produce a reduced gl.h header file which only defines the
+tokens and functions which are implemented by the subset?<br>
+<br>
+RECOMMENDATION: yes. &nbsp;It would be a useful reference to
+programmers to quickly determine which functions and tokens are
+supported.<br>
+<br>
+RESOLUTION: open<br>
+<br>
+<h2>A.15 glPolygonMode</h2>
+Is <span style="font-weight: bold;">glPolygonMode</span> needed?<br>
+<br>
+RECOMMENDATION: No. &nbsp;Omit it.<br>
+<br>
+RESOLUTION: closed, as of 26 Feb 2003<br>

+
+<p>
+Mesa was originally designed for Unix/X11 systems and is still best
+supported on those systems. All you need is an ANSI C compiler and the
+X development environment to use Mesa.
+</p>
+
+<p>
+The DRI hardware drivers for the X.org server and XFree86 provide
+hardware accelerated rendering for chips from ATI, Intel, Matrox, 3dfx
+and others on Linux and FreeBSD.
+</p>
+
+<p>
+Drivers for other assorted platforms include:
+the Amiga, Apple Macintosh, BeOS, NeXT, OS/2, MS-DOS, VMS, Windows
+9x/NT, and Direct3D.

+*               performance. Utilizes the VESA VBE/AF Accelerator Functions

+*               via the MGL's accelerated device driver functions, as well

+*               as basic DirectDraw accelerated functions provided by the

+*               MGL.

+ * Mesa Off-Screen rendering interface.
+ *
+ * This is an operating system and window system independent interface to
+ * Mesa which allows one to render images into a client-supplied buffer in
+ * main memory.  Such images may manipulated or saved in whatever way the
+ * client wants.
+ *
+ * These are the API functions:
+ *   OSMesaCreateContext - create a new Off-Screen Mesa rendering context
+ *   OSMesaMakeCurrent - bind an OSMesaContext to a client's image buffer
+ *                       and make the specified context the current one.
+ *   OSMesaDestroyContext - destroy an OSMesaContext
+ *   OSMesaGetCurrentContext - return thread's current context ID
+ *   OSMesaPixelStore - controls how pixels are stored in image buffer
+ *   OSMesaGetIntegerv - return OSMesa state parameters
+ *
+ *
+ * The limits on the width and height of an image buffer are MAX_WIDTH and
+ * MAX_HEIGHT as defined in Mesa/src/config.h.  Defaults are 1280 and 1024.
+ * You can increase them as needed but beware that many temporary arrays in
+ * Mesa are dimensioned by MAX_WIDTH or MAX_HEIGHT.

+/* Sample Usage:
+
+In addition to the usual X calls to select a visual, create a colormap
+and create a window, you must do the following to use the X/Mesa interface:
+
+1. Call XMesaCreateVisual() to make an XMesaVisual from an XVisualInfo.
+
+2. Call XMesaCreateContext() to create an X/Mesa rendering context, given
+   the XMesaVisual.
+
+3. Call XMesaCreateWindowBuffer() to create an XMesaBuffer from an X window
+   and XMesaVisual.
+
+4. Call XMesaMakeCurrent() to bind the XMesaBuffer to an XMesaContext and
+   to make the context the current one.
+
+5. Make gl* calls to render your graphics.
+
+6. Use XMesaSwapBuffers() when double buffering to swap front/back buffers.
+
+7. Before the X window is destroyed, call XMesaDestroyBuffer().
+
+8. Before exiting, call XMesaDestroyVisual and XMesaDestroyContext.

+ * From: Stephane Rehel <rehel@worldnet.fr>
+ * Date: Mon, 31 May 1999 18:40:54 -0400
+ * To: Paul Brian <brianp@ra.avid.com>
+ * Subject: OpenGL State Dump Function
+ * 
+ * Here is a function that dumps the current OpenGL state. I wrote it
+ * some time ago.
+ * 
+ * In the attachment:
+ *   + the code itself
+ *   + its output
+ * 
+ * I think Mesa is wrong on some getBooleanv(). For example, GL_VERTEX_ARRAY
+ * is queried by IsEnabled() (cf. p. 196 of the spec). But on page 193
+ * we can read that all the boolean attribs that can be queried by IsEnabled()
+ * can also be queried by IsEnabled().
+ * 
+ * I had duplicated all the enums (LOCAL_*) so that the code can run on any 
+ * OpenGL version, even if an enum is not recognized.
+ * 
+ * The code can be shipped in the public domain.
+ * 
+ * Stephane.

+DESCRIPTION 'Mesa GLU (OpenGL work-alike) for Win32'
+VERSION 5.1
+;
+; Module definition file for GLU (GLU32.DLL)
+;
+; Note: The GLU functions use the STDCALL
+; function calling convention.  Microsoft's
+; GLU32 uses this convention and so must the
+; Mesa GLU32 so that the Mesa DLL can be used
+; as a drop-in replacement.
+;
+; The linker exports STDCALL entry points with
+; 'decorated' names; e.g., _glBegin@0, where the
+; trailing number is the number of bytes of 
+; parameter data pushed onto the stack.  The
+; callee is responsible for popping this data
+; off the stack, usually via a RETF n instruction.
+;
+; However, the Microsoft GLU32.DLL does not export
+; the decorated names, even though the calling convention
+; is STDCALL.  So, this module definition file is
+; needed to force the Mesa GLU32.DLL to export the
+; symbols in the same manner as the Microsoft DLL.
+; Were it not for this problem, this file would not
+; be needed (for the glu* functions) since the entry
+; points are compiled with dllexport declspec.

+General Polygon Tesselation
+---------------------------
+
+  This note describes a tesselator for polygons consisting of one or
+  more closed contours.  It is backward-compatible with the current
+  OpenGL Utilities tesselator, and is intended to replace it.  Here is
+  a summary of the major differences:
+
+   - input contours can be intersecting, self-intersecting, or degenerate.
+  
+   - supports a choice of several winding rules for determining which parts
+     of the polygon are on the "interior".  This makes it possible to do
+     CSG operations on polygons.
+  
+   - boundary extraction: instead of tesselating the polygon, returns a
+     set of closed contours which separate the interior from the exterior.
+  
+   - returns the output as a small number of triangle fans and strips,
+     rather than a list of independent triangles (when possible).
+  
+   - output is available as an explicit mesh (a quad-edge structure),
+     in addition to the normal callback interface.
+  
+   - the algorithm used is extremely robust.
+
+
+The interface
+-------------
+
+  The tesselator state is maintained in a "tesselator object".
+  These are allocated and destroyed using
+
+     GLUtesselator *gluNewTess( void );
+     void gluDeleteTess( GLUtesselator *tess );
+
+  Several tesselator objects may be used simultaneously.
+
+  Inputs
+  ------
+  
+  The input contours are specified with the following routines:
+
+     void gluTessBeginPolygon( GLUtesselator *tess );
+     void gluTessBeginContour( GLUtesselator *tess );
+     void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data );
+     void gluTessEndContour( GLUtesselator *tess );
+     void gluTessEndPolygon( GLUtesselator *tess );
+
+  Within each BeginPolygon/EndPolygon pair, there can be zero or more
+  calls to BeginContour/EndContour.  Within each contour, there are zero
+  or more calls to gluTessVertex().  The vertices specify a closed
+  contour (the last vertex of each contour is automatically linked to
+  the first).
+
+  "coords" give the coordinates of the vertex in 3-space.  For useful
+  results, all vertices should lie in some plane, since the vertices
+  are projected onto a plane before tesselation.  "data" is a pointer
+  to a user-defined vertex structure, which typically contains other
+  information such as color, texture coordinates, normal, etc.  It is
+  used to refer to the vertex during rendering.
+
+  The library can be compiled in single- or double-precision; the type
+  GLUcoord represents either "float" or "double" accordingly.  The GLU
+  version will be available in double-precision only.  Compile with
+  GLU_TESS_API_FLOAT defined to get the single-precision version.
+
+  When EndPolygon is called, the tesselation algorithm determines
+  which regions are interior to the given contours, according to one
+  of several "winding rules" described below.  The interior regions
+  are then tesselated, and the output is provided as callbacks.
+
+
+  Rendering Callbacks
+  -------------------
+
+  Callbacks are specified by the client using
+
+     void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)());
+
+  If "fn" is NULL, any previously defined callback is discarded.
+  
+  The callbacks used to provide output are:	/* which == */
+
+     void begin( GLenum type );			/* GLU_TESS_BEGIN */
+     void edgeFlag( GLboolean flag );		/* GLU_TESS_EDGE_FLAG */
+     void vertex( void *data );			/* GLU_TESS_VERTEX */
+     void end( void );				/* GLU_TESS_END */
+
+  Any of the callbacks may be left undefined; if so, the corresponding
+  information will not be supplied during rendering.
+
+  The "begin" callback indicates the start of a primitive; type is one
+  of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the
+  notes on "boundary extraction" below).
+  
+  It is followed by any number of "vertex" callbacks, which supply the
+  vertices in the same order as expected by the corresponding glBegin()
+  call.  After the last vertex of a given primitive, there is a callback
+  to "end".
+
+  If the "edgeFlag" callback is provided, no triangle fans or strips
+  will be used.  When edgeFlag is called, if "flag" is GL_TRUE then each
+  vertex which follows begins an edge which lies on the polygon boundary
+  (ie. an edge which separates an interior region from an exterior one).
+  If "flag" is GL_FALSE, each vertex which follows begins an edge which lies
+  in the polygon interior.  "edgeFlag" will be called before the first
+  call to "vertex".
+
+  Other Callbacks
+  ---------------
+
+   void mesh( GLUmesh *mesh );			/* GLU_TESS_MESH */
+
+   - Returns an explicit mesh, represented using the quad-edge structure
+     (Guibas/Stolfi '85).  Other implementations of this interface might
+     use a different mesh structure, so this is available only only as an
+     SGI extension.  When the mesh is no longer needed, it should be freed
+     using
+
+	void gluDeleteMesh( GLUmesh *mesh );
+
+     There is a brief description of this data structure in the include
+     file "mesh.h".  For the full details, see L. Guibas and J. Stolfi,
+     Primitives for the manipulation of general subdivisions and the
+     computation of Voronoi diagrams, ACM Transactions on Graphics,
+     4(2):74-123, April 1985.  For an introduction, see the course notes
+     for CS348a, "Mathematical Foundations of Computer Graphics",
+     available at the Stanford bookstore (and taught during the fall
+     quarter).
+
+   void error( GLenum errno );			/* GLU_TESS_ERROR */
+
+   - errno is one of	GLU_TESS_MISSING_BEGIN_POLYGON,
+			GLU_TESS_MISSING_END_POLYGON,
+			GLU_TESS_MISSING_BEGIN_CONTOUR,
+			GLU_TESS_MISSING_END_CONTOUR,
+			GLU_TESS_COORD_TOO_LARGE,
+			GLU_TESS_NEED_COMBINE_CALLBACK
+
+     The first four are obvious.  The interface recovers from these
+     errors by inserting the missing call(s).
+  
+     GLU_TESS_COORD_TOO_LARGE says that some vertex coordinate exceeded
+     the predefined constant GLU_TESS_MAX_COORD in absolute value, and
+     that the value has been clamped.  (Coordinate values must be small
+     enough so that two can be multiplied together without overflow.)
+
+     GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an
+     intersection between two edges in the input data, and the "combine"
+     callback (below) was not provided.  No output will be generated.
+
+
+   void combine( GLUcoord coords[3], void *data[4],	/* GLU_TESS_COMBINE */
+		 GLUcoord weight[4], void **outData );
+
+   - When the algorithm detects an intersection, or wishes to merge
+     features, it needs to create a new vertex.  The vertex is defined
+     as a linear combination of up to 4 existing vertices, referenced
+     by data[0..3].  The coefficients of the linear combination are
+     given by weight[0..3]; these weights always sum to 1.0.  All vertex
+     pointers are valid even when some of the weights are zero.
+     "coords" gives the location of the new vertex.
+
+     The user must allocate another vertex, interpolate parameters
+     using "data" and "weights", and return the new vertex pointer in
+     "outData".  This handle is supplied during rendering callbacks.
+     For example, if the polygon lies in an arbitrary plane in 3-space,
+     and we associate a color with each vertex, the combine callback might
+     look like this:
+    
+     void myCombine( GLUcoord coords[3], VERTEX *d[4],
+                     GLUcoord w[4], VERTEX **dataOut )
+     {
+        VERTEX *new = new_vertex();
+       
+        new->x = coords[0];
+        new->y = coords[1];
+        new->z = coords[2];
+        new->r = w[0]*d[0]->r + w[1]*d[1]->r + w[2]*d[2]->r + w[3]*d[3]->r;
+        new->g = w[0]*d[0]->g + w[1]*d[1]->g + w[2]*d[2]->g + w[3]*d[3]->g;
+        new->b = w[0]*d[0]->b + w[1]*d[1]->b + w[2]*d[2]->b + w[3]*d[3]->b;
+        new->a = w[0]*d[0]->a + w[1]*d[1]->a + w[2]*d[2]->a + w[3]*d[3]->a;
+        *dataOut = new;
+     }
+
+     If the algorithm detects an intersection, then the "combine" callback
+     must be defined, and must write a non-NULL pointer into "dataOut".
+     Otherwise the GLU_TESS_NEED_COMBINE_CALLBACK error occurs, and no
+     output is generated.  This is the only error that can occur during
+     tesselation and rendering.
+
+
+  Control over Tesselation
+  ------------------------
+  
+   void gluTessProperty( GLUtesselator *tess, GLenum which, GLUcoord value );
+
+   Properties defined:
+
+    - GLU_TESS_WINDING_RULE.  Possible values:
+
+	  GLU_TESS_WINDING_ODD
+	  GLU_TESS_WINDING_NONZERO
+	  GLU_TESS_WINDING_POSITIVE
+	  GLU_TESS_WINDING_NEGATIVE
+	  GLU_TESS_WINDING_ABS_GEQ_TWO
+
+      The input contours parition the plane into regions.  A winding
+      rule determines which of these regions are inside the polygon.
+      
+      For a single contour C, the winding number of a point x is simply
+      the signed number of revolutions we make around x as we travel
+      once around C (where CCW is positive).  When there are several
+      contours, the individual winding numbers are summed.  This
+      procedure associates a signed integer value with each point x in
+      the plane.  Note that the winding number is the same for all
+      points in a single region.
+
+      The winding rule classifies a region as "inside" if its winding
+      number belongs to the chosen category (odd, nonzero, positive,
+      negative, or absolute value of at least two).  The current GLU
+      tesselator implements the "odd" rule.  The "nonzero" rule is another
+      common way to define the interior.  The other three rules are
+      useful for polygon CSG operations (see below).
+
+    - GLU_TESS_BOUNDARY_ONLY.  Values: TRUE (non-zero) or FALSE (zero).
+
+      If TRUE, returns a set of closed contours which separate the
+      polygon interior and exterior (rather than a tesselation).
+      Exterior contours are oriented CCW with respect to the normal,
+      interior contours are oriented CW.  The GLU_TESS_BEGIN callback
+      uses the type GL_LINE_LOOP for each contour.
+      
+    - GLU_TESS_TOLERANCE.  Value: a real number between 0.0 and 1.0.
+
+      This specifies a tolerance for merging features to reduce the size
+      of the output.  For example, two vertices which are very close to
+      each other might be replaced by a single vertex.  The tolerance
+      is multiplied by the largest coordinate magnitude of any input vertex;
+      this specifies the maximum distance that any feature can move as the
+      result of a single merge operation.  If a single feature takes part
+      in several merge operations, the total distance moved could be larger.
+
+      Feature merging is completely optional; the tolerance is only a hint.
+      The implementation is free to merge in some cases and not in others,
+      or to never merge features at all.  The default tolerance is zero.
+      
+      The current implementation merges vertices only if they are exactly
+      coincident, regardless of the current tolerance.  A vertex is
+      spliced into an edge only if the implementation is unable to
+      distinguish which side of the edge the vertex lies on.
+      Two edges are merged only when both endpoints are identical.
+
+
+   void gluTessNormal( GLUtesselator *tess,
+		      GLUcoord x, GLUcoord y, GLUcoord z )
+
+    - Lets the user supply the polygon normal, if known.  All input data
+      is projected into a plane perpendicular to the normal before
+      tesselation.  All output triangles are oriented CCW with
+      respect to the normal (CW orientation can be obtained by
+      reversing the sign of the supplied normal).  For example, if
+      you know that all polygons lie in the x-y plane, call
+      "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons.
+      
+    - If the supplied normal is (0,0,0) (the default value), the
+      normal is determined as follows.  The direction of the normal,
+      up to its sign, is found by fitting a plane to the vertices,
+      without regard to how the vertices are connected.  It is
+      expected that the input data lies approximately in plane;
+      otherwise projection perpendicular to the computed normal may
+      substantially change the geometry.  The sign of the normal is
+      chosen so that the sum of the signed areas of all input contours
+      is non-negative (where a CCW contour has positive area).
+    
+    - The supplied normal persists until it is changed by another
+      call to gluTessNormal.
+
+
+  Backward compatibility with the GLU tesselator
+  ----------------------------------------------
+
+  The preferred interface is the one described above.  The following
+  routines are obsolete, and are provided only for backward compatibility:
+
+    typedef GLUtesselator GLUtriangulatorObj;	/* obsolete name */
+
+    void gluBeginPolygon( GLUtesselator *tess );
+    void gluNextContour( GLUtesselator *tess, GLenum type );
+    void gluEndPolygon( GLUtesselator *tess );
+  
+  "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or
+  GLU_UNKNOWN.  It is ignored by the current GLU tesselator.
+  
+  GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined
+  as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END,
+  GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG.
+
+
+Polygon CSG operations
+----------------------
+
+  The features of the tesselator make it easy to find the union, difference,
+  or intersection of several polygons.
+
+  First, assume that each polygon is defined so that the winding number
+  is 0 for each exterior region, and 1 for each interior region.  Under
+  this model, CCW contours define the outer boundary of the polygon, and
+  CW contours define holes.  Contours may be nested, but a nested
+  contour must be oriented oppositely from the contour that contains it.
+
+  If the original polygons do not satisfy this description, they can be
+  converted to this form by first running the tesselator with the
+  GLU_TESS_BOUNDARY_ONLY property turned on.  This returns a list of
+  contours satisfying the restriction above.  By allocating two
+  tesselator objects, the callbacks from one tesselator can be fed
+  directly to the input of another.
+
+  Given two or more polygons of the form above, CSG operations can be
+  implemented as follows:
+
+  Union
+     Draw all the input contours as a single polygon.  The winding number
+     of each resulting region is the number of original polygons
+     which cover it.  The union can be extracted using the
+     GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules.
+     Note that with the nonzero rule, we would get the same result if
+     all contour orientations were reversed.
+
+  Intersection (two polygons at a time only)
+     Draw a single polygon using the contours from both input polygons.
+     Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO.  (Since this
+     winding rule looks at the absolute value, reversing all contour
+     orientations does not change the result.)
+
+  Difference
+  
+     Suppose we want to compute A \ (B union C union D).  Draw a single
+     polygon consisting of the unmodified contours from A, followed by
+     the contours of B,C,D with the vertex order reversed (this changes
+     the winding number of the interior regions to -1).  To extract the
+     result, use the GLU_TESS_WINDING_POSITIVE rule.
+   
+     If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an
+     alternative to reversing the vertex order is to reverse the sign of
+     the supplied normal.  For example in the x-y plane, call
+     gluTessNormal( tess, 0.0, 0.0, -1.0 ).
+ 
+
+Performance
+-----------
+
+  The tesselator is not intended for immediate-mode rendering; when
+  possible the output should be cached in a user structure or display
+  list.  General polygon tesselation is an inherently difficult problem,
+  especially given the goal of extreme robustness.
+
+  The implementation makes an effort to output a small number of fans
+  and strips; this should improve the rendering performance when the
+  output is used in a display list.
+
+  Single-contour input polygons are first tested to see whether they can
+  be rendered as a triangle fan with respect to the first vertex (to
+  avoid running the full decomposition algorithm on convex polygons).
+  Non-convex polygons may be rendered by this "fast path" as well, if
+  the algorithm gets lucky in its choice of a starting vertex.
+
+  For best performance follow these guidelines:
+
+   - supply the polygon normal, if available, using gluTessNormal().
+     This represents about 10% of the computation time.  For example,
+     if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1).
+
+   - render many polygons using the same tesselator object, rather than
+     allocating a new tesselator for each one.  (In a multi-threaded,
+     multi-processor environment you may get better performance using
+     several tesselators.)
+
+
+Comparison with the GLU tesselator
+----------------------------------
+
+  On polygons which make it through the "fast path", the tesselator is
+  3 to 5 times faster than the GLU tesselator.
+
+  On polygons which don't make it through the fast path (but which don't
+  have self-intersections or degeneracies), it is about 2 times slower.
+
+  On polygons with self-intersections or degeneraces, there is nothing
+  to compare against.
+
+  The new tesselator generates many more fans and strips, reducing the
+  number of vertices that need to be sent to the hardware.
+
+  Key to the statistics:
+
+	vert		number of input vertices on all contours
+	cntr		number of input contours
+	tri		number of triangles in all output primitives
+	strip		number of triangle strips
+	fan		number of triangle fans
+	ind		number of independent triangles
+	ms		number of milliseconds for tesselation
+			(on a 150MHz R4400 Indy)

+This is only a very brief overview.  There is quite a bit of
+additional documentation in the source code itself.
+
+
+Goals of robust tesselation
+---------------------------
+
+The tesselation algorithm is fundamentally a 2D algorithm.  We
+initially project all data into a plane; our goal is to robustly
+tesselate the projected data.  The same topological tesselation is
+then applied to the input data.
+
+Topologically, the output should always be a tesselation.  If the
+input is even slightly non-planar, then some triangles will
+necessarily be back-facing when viewed from some angles, but the goal
+is to minimize this effect.
+
+The algorithm needs some capability of cleaning up the input data as
+well as the numerical errors in its own calculations.  One way to do
+this is to specify a tolerance as defined above, and clean up the
+input and output during the line sweep process.  At the very least,
+the algorithm must handle coincident vertices, vertices incident to an
+edge, and coincident edges.
+
+
+Phases of the algorithm
+-----------------------
+
+1. Find the polygon normal N.
+2. Project the vertex data onto a plane.  It does not need to be
+   perpendicular to the normal, eg. we can project onto the plane
+   perpendicular to the coordinate axis whose dot product with N
+   is largest.
+3. Using a line-sweep algorithm, partition the plane into x-monotone
+   regions.  Any vertical line intersects an x-monotone region in
+   at most one interval.
+4. Triangulate the x-monotone regions.
+5. Group the triangles into strips and fans.
+
+
+Finding the normal vector
+-------------------------
+
+A common way to find a polygon normal is to compute the signed area
+when the polygon is projected along the three coordinate axes.  We
+can't do this, since contours can have zero area without being
+degenerate (eg. a bowtie).
+
+We fit a plane to the vertex data, ignoring how they are connected
+into contours.  Ideally this would be a least-squares fit; however for
+our purpose the accuracy of the normal is not important.  Instead we
+find three vertices which are widely separated, and compute the normal
+to the triangle they form.  The vertices are chosen so that the
+triangle has an area at least 1/sqrt(3) times the largest area of any
+triangle formed using the input vertices.  
+
+The contours do affect the orientation of the normal; after computing
+the normal, we check that the sum of the signed contour areas is
+non-negative, and reverse the normal if necessary.
+
+
+Projecting the vertices
+-----------------------
+
+We project the vertices onto a plane perpendicular to one of the three
+coordinate axes.  This helps numerical accuracy by removing a
+transformation step between the original input data and the data
+processed by the algorithm.  The projection also compresses the input
+data; the 2D distance between vertices after projection may be smaller
+than the original 2D distance.  However by choosing the coordinate
+axis whose dot product with the normal is greatest, the compression
+factor is at most 1/sqrt(3).
+
+Even though the *accuracy* of the normal is not that important (since
+we are projecting perpendicular to a coordinate axis anyway), the
+*robustness* of the computation is important.  For example, if there
+are many vertices which lie almost along a line, and one vertex V
+which is well-separated from the line, then our normal computation
+should involve V otherwise the results will be garbage.
+
+The advantage of projecting perpendicular to the polygon normal is
+that computed intersection points will be as close as possible to
+their ideal locations.  To get this behavior, define TRUE_PROJECT.
+
+
+The Line Sweep
+--------------
+
+There are three data structures: the mesh, the event queue, and the
+edge dictionary.
+
+The mesh is a "quad-edge" data structure which records the topology of
+the current decomposition; for details see the include file "mesh.h".
+
+The event queue simply holds all vertices (both original and computed
+ones), organized so that we can quickly extract the vertex with the
+minimum x-coord (and among those, the one with the minimum y-coord).
+
+The edge dictionary describes the current intersection of the sweep
+line with the regions of the polygon.  This is just an ordering of the
+edges which intersect the sweep line, sorted by their current order of
+intersection.  For each pair of edges, we store some information about
+the monotone region between them -- these are call "active regions"
+(since they are crossed by the current sweep line).
+
+The basic algorithm is to sweep from left to right, processing each
+vertex.  The processed portion of the mesh (left of the sweep line) is
+a planar decomposition.  As we cross each vertex, we update the mesh
+and the edge dictionary, then we check any newly adjacent pairs of
+edges to see if they intersect.
+
+A vertex can have any number of edges.  Vertices with many edges can
+be created as vertices are merged and intersection points are
+computed.  For unprocessed vertices (right of the sweep line), these
+edges are in no particular order around the vertex; for processed
+vertices, the topological ordering should match the geometric ordering.
+
+The vertex processing happens in two phases: first we process are the
+left-going edges (all these edges are currently in the edge
+dictionary).  This involves:
+
+ - deleting the left-going edges from the dictionary;
+ - relinking the mesh if necessary, so that the order of these edges around
+   the event vertex matches the order in the dictionary;
+ - marking any terminated regions (regions which lie between two left-going
+   edges) as either "inside" or "outside" according to their winding number.
+
+When there are no left-going edges, and the event vertex is in an
+"interior" region, we need to add an edge (to split the region into
+monotone pieces).  To do this we simply join the event vertex to the
+rightmost left endpoint of the upper or lower edge of the containing
+region.
+
+Then we process the right-going edges.  This involves:
+
+ - inserting the edges in the edge dictionary;
+ - computing the winding number of any newly created active regions.
+   We can compute this incrementally using the winding of each edge
+   that we cross as we walk through the dictionary.
+ - relinking the mesh if necessary, so that the order of these edges around
+   the event vertex matches the order in the dictionary;
+ - checking any newly adjacent edges for intersection and/or merging.
+
+If there are no right-going edges, again we need to add one to split
+the containing region into monotone pieces.  In our case it is most
+convenient to add an edge to the leftmost right endpoint of either
+containing edge; however we may need to change this later (see the
+code for details).
+
+
+Invariants
+----------
+
+These are the most important invariants maintained during the sweep.
+We define a function VertLeq(v1,v2) which defines the order in which
+vertices cross the sweep line, and a function EdgeLeq(e1,e2; loc)
+which says whether e1 is below e2 at the sweep event location "loc".
+This function is defined only at sweep event locations which lie
+between the rightmost left endpoint of {e1,e2}, and the leftmost right
+endpoint of {e1,e2}.
+
+Invariants for the Edge Dictionary.
+
+ - Each pair of adjacent edges e2=Succ(e1) satisfies EdgeLeq(e1,e2)
+   at any valid location of the sweep event.
+ - If EdgeLeq(e2,e1) as well (at any valid sweep event), then e1 and e2
+   share a common endpoint.
+ - For each e in the dictionary, e->Dst has been processed but not e->Org.
+ - Each edge e satisfies VertLeq(e->Dst,event) && VertLeq(event,e->Org)
+   where "event" is the current sweep line event.
+ - No edge e has zero length.
+ - No two edges have identical left and right endpoints.
+ 
+Invariants for the Mesh (the processed portion).
+
+ - The portion of the mesh left of the sweep line is a planar graph,
+   ie. there is *some* way to embed it in the plane.
+ - No processed edge has zero length.
+ - No two processed vertices have identical coordinates.
+ - Each "inside" region is monotone, ie. can be broken into two chains
+   of monotonically increasing vertices according to VertLeq(v1,v2)
+   - a non-invariant: these chains may intersect (slightly) due to
+     numerical errors, but this does not affect the algorithm's operation.
+
+Invariants for the Sweep.
+
+ - If a vertex has any left-going edges, then these must be in the edge
+   dictionary at the time the vertex is processed.
+ - If an edge is marked "fixUpperEdge" (it is a temporary edge introduced
+   by ConnectRightVertex), then it is the only right-going edge from
+   its associated vertex.  (This says that these edges exist only
+   when it is necessary.)
+
+
+Robustness
+----------
+
+The key to the robustness of the algorithm is maintaining the
+invariants above, especially the correct ordering of the edge
+dictionary.  We achieve this by:
+
+  1. Writing the numerical computations for maximum precision rather
+     than maximum speed.
+     
+  2. Making no assumptions at all about the results of the edge
+     intersection calculations -- for sufficiently degenerate inputs,
+     the computed location is not much better than a random number.
+     
+  3. When numerical errors violate the invariants, restore them
+     by making *topological* changes when necessary (ie. relinking
+     the mesh structure).
+     
+     
+Triangulation and Grouping
+--------------------------
+
+We finish the line sweep before doing any triangulation.  This is
+because even after a monotone region is complete, there can be further
+changes to its vertex data because of further vertex merging.
+
+After triangulating all monotone regions, we want to group the
+triangles into fans and strips.  We do this using a greedy approach.
+The triangulation itself is not optimized to reduce the number of
+primitives; we just try to get a reasonable decomposition of the
+computed triangulation.

+/* The mesh structure is similar in spirit, notation, and operations
+ * to the "quad-edge" structure (see L. Guibas and J. Stolfi, Primitives
+ * for the manipulation of general subdivisions and the computation of
+ * Voronoi diagrams, ACM Transactions on Graphics, 4(2):74-123, April 1985).
+ * For a simplified description, see the course notes for CS348a,
+ * "Mathematical Foundations of Computer Graphics", available at the
+ * Stanford bookstore (and taught during the fall quarter).
+ * The implementation also borrows a tiny subset of the graph-based approach
+ * use in Mantyla's Geometric Work Bench (see M. Mantyla, An Introduction
+ * to Sold Modeling, Computer Science Press, Rockville, Maryland, 1988).
+ *
+ * The fundamental data structure is the "half-edge".  Two half-edges
+ * go together to make an edge, but they point in opposite directions.
+ * Each half-edge has a pointer to its mate (the "symmetric" half-edge Sym),
+ * its origin vertex (Org), the face on its left side (Lface), and the
+ * adjacent half-edges in the CCW direction around the origin vertex
+ * (Onext) and around the left face (Lnext).  There is also a "next"
+ * pointer for the global edge list (see below).
+ *
+ * The notation used for mesh navigation:
+ *	Sym   = the mate of a half-edge (same edge, but opposite direction)
+ *	Onext = edge CCW around origin vertex (keep same origin)
+ *	Dnext = edge CCW around destination vertex (keep same dest)
+ *	Lnext = edge CCW around left face (dest becomes new origin)
+ *	Rnext = edge CCW around right face (origin becomes new dest)
+ *
+ * "prev" means to substitute CW for CCW in the definitions above.
+ *
+ * The mesh keeps global lists of all vertices, faces, and edges,
+ * stored as doubly-linked circular lists with a dummy header node.
+ * The mesh stores pointers to these dummy headers (vHead, fHead, eHead).
+ *
+ * The circular edge list is special; since half-edges always occur
+ * in pairs (e and e->Sym), each half-edge stores a pointer in only
+ * one direction.  Starting at eHead and following the e->next pointers
+ * will visit each *edge* once (ie. e or e->Sym, but not both).
+ * e->Sym stores a pointer in the opposite direction, thus it is
+ * always true that e->Sym->next->Sym->next == e.
+ *
+ * Each vertex has a pointer to next and previous vertices in the
+ * circular list, and a pointer to a half-edge with this vertex as
+ * the origin (NULL if this is the dummy header).  There is also a
+ * field "data" for client data.
+ *
+ * Each face has a pointer to the next and previous faces in the
+ * circular list, and a pointer to a half-edge with this face as
+ * the left face (NULL if this is the dummy header).  There is also
+ * a field "data" for client data.
+ *
+ * Note that what we call a "face" is really a loop; faces may consist
+ * of more than one loop (ie. not simply connected), but there is no
+ * record of this in the data structure.  The mesh may consist of
+ * several disconnected regions, so it may not be possible to visit
+ * the entire mesh by starting at a half-edge and traversing the edge
+ * structure.
+ *
+ * The mesh does NOT support isolated vertices; a vertex is deleted along
+ * with its last edge.  Similarly when two faces are merged, one of the
+ * faces is deleted (see __gl_meshDelete below).  For mesh operations,
+ * all face (loop) and vertex pointers must not be NULL.  However, once
+ * mesh manipulation is finished, __gl_MeshZapFace can be used to delete
+ * faces of the mesh, one at a time.  All external faces can be "zapped"
+ * before the mesh is returned to the client; then a NULL face indicates
+ * a region which is not part of the output polygon.

+/* The mesh operations below have three motivations: completeness,
+ * convenience, and efficiency.  The basic mesh operations are MakeEdge,
+ * Splice, and Delete.  All the other edge operations can be implemented
+ * in terms of these.  The other operations are provided for convenience
+ * and/or efficiency.
+ *
+ * When a face is split or a vertex is added, they are inserted into the
+ * global list *before* the existing vertex or face (ie. e->Org or e->Lface).
+ * This makes it easier to process all vertices or faces in the global lists
+ * without worrying about processing the same data twice.  As a convenience,
+ * when a face is split, the "inside" flag is copied from the old face.
+ * Other internal data (v->data, v->activeRegion, f->data, f->marked,
+ * f->trail, e->winding) is set to zero.
+ *
+ * ********************** Basic Edge Operations **************************
+ *
+ * __gl_meshMakeEdge( mesh ) creates one edge, two vertices, and a loop.
+ * The loop (face) consists of the two new half-edges.
+ *
+ * __gl_meshSplice( eOrg, eDst ) is the basic operation for changing the
+ * mesh connectivity and topology.  It changes the mesh so that
+ *	eOrg->Onext <- OLD( eDst->Onext )
+ *	eDst->Onext <- OLD( eOrg->Onext )
+ * where OLD(...) means the value before the meshSplice operation.
+ *
+ * This can have two effects on the vertex structure:
+ *  - if eOrg->Org != eDst->Org, the two vertices are merged together
+ *  - if eOrg->Org == eDst->Org, the origin is split into two vertices
+ * In both cases, eDst->Org is changed and eOrg->Org is untouched.
+ *
+ * Similarly (and independently) for the face structure,
+ *  - if eOrg->Lface == eDst->Lface, one loop is split into two
+ *  - if eOrg->Lface != eDst->Lface, two distinct loops are joined into one
+ * In both cases, eDst->Lface is changed and eOrg->Lface is unaffected.
+ *
+ * __gl_meshDelete( eDel ) removes the edge eDel.  There are several cases:
+ * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop
+ * eDel->Lface is deleted.  Otherwise, we are splitting one loop into two;
+ * the newly created loop will contain eDel->Dst.  If the deletion of eDel
+ * would create isolated vertices, those are deleted as well.
+ *
+ * ********************** Other Edge Operations **************************
+ *
+ * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that
+ * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex.
+ * eOrg and eNew will have the same left face.
+ *
+ * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew,
+ * such that eNew == eOrg->Lnext.  The new vertex is eOrg->Dst == eNew->Org.
+ * eOrg and eNew will have the same left face.
+ *
+ * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst
+ * to eDst->Org, and returns the corresponding half-edge eNew.
+ * If eOrg->Lface == eDst->Lface, this splits one loop into two,
+ * and the newly created loop is eNew->Lface.  Otherwise, two disjoint
+ * loops are merged into one, and the loop eDst->Lface is destroyed.
+ *
+ * ************************ Other Operations *****************************
+ *
+ * __gl_meshNewMesh() creates a new mesh with no edges, no vertices,
+ * and no loops (what we usually call a "face").
+ *
+ * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in
+ * both meshes, and returns the new mesh (the old meshes are destroyed).
+ *
+ * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh.
+ *
+ * __gl_meshZapFace( fZap ) destroys a face and removes it from the
+ * global face list.  All edges of fZap will have a NULL pointer as their
+ * left face.  Any edges which also have a NULL pointer as their right face
+ * are deleted entirely (along with any isolated vertices this produces).
+ * An entire mesh can be deleted by zapping its faces, one at a time,
+ * in any order.  Zapped faces cannot be used in further mesh operations!
+ *
+ * __gl_meshCheckMesh( mesh ) checks a mesh for self-consistency.

+ * There are two reasons for doing this (adding a right-going edge):

+ *    to keep them separated (the combined region would not be monotone).
+ *  - in any case, we must leave some record of vEvent in the dictionary,

+ *    For example, maybe there is a vertical edge which passes just to

+
+
+This directory contains the source code for SGI's OpenGL Xt/Motif widgets,
+slightly modified by Jeroen van der Zijp to work better with Mesa.
+
+To compile the widget code (producing lib/libGLw.a) cd to the widgets/
+directory and type 'make <config>' where <config> is the system configuration
+you used to compile Mesa (like 'make linux').  This hasn't been tested on
+many systems so let us know if you have trouble.
+
+If you want to make a Linux ELF shared lib instead of the non-shared .a
+file see the notes in the Makefile.
+
+If you want to build with Motif support, edit Makefile.X11, looking
+for the "Motif" information.
+
+The SGI copyright is as follows.

+ * DRI there is a similar but slightly different issue.  When GLX 1.3 is

+ * just call the driver's \c __DRIdrawableRec::destroyDrawable function.
+ * This would reduce the frequency with which \c __driGarbageCollectDrawables

+ * \file indirect_vertex_array.c
+ * Implement GLX protocol for vertex arrays and vertex buffer objects.
+ * 
+ * The most important function in this fill is \c fill_array_info_cache.
+ * The \c array_state_vector contains a cache of the ARRAY_INFO data sent
+ * in the DrawArrays protocol.  Certain operations, such as enabling or
+ * disabling an array, can invalidate this cache.  \c fill_array_info_cache
+ * fills-in this data.  Additionally, it examines the enabled state and
+ * other factors to determine what "version" of DrawArrays protocoal can be
+ * used.
+ * 
+ * Current, only two versions of DrawArrays protocol are implemented.  The
+ * first version is the "none" protocol.  This is the fallback when the
+ * server does not support GL 1.1 / EXT_vertex_arrays.  It is implemented
+ * by sending batches of immediate mode commands that are equivalent to the
+ * DrawArrays protocol.
+ *
+ * The other protocol that is currently implemented is the "old" protocol.
+ * This is the GL 1.1 DrawArrays protocol.  The only difference between GL
+ * 1.1 and EXT_vertex_arrays is the opcode used for the DrawArrays command.
+ * This protocol is called "old" because the ARB is in the process of
+ * defining a new protocol, which will probably be called wither "new" or
+ * "vbo", to support multiple texture coordinate arrays, generic attributes,
+ * and vertex buffer objects.

+ * DRI utility functions.
+ *
+ * This module acts as glue between GLX and the actual hardware driver.  A DRI
+ * driver doesn't really \e have to use any of this - it's optional.  But, some
+ * useful stuff is done here that otherwise would have to be duplicated in most
+ * drivers.
+ * 
+ * Basically, these utility functions take care of some of the dirty details of
+ * screen initialization, context creation, context binding, DRM setup, etc.
+ *
+ * These functions are compiled into each DRI driver so libGL.so knows nothing
+ * about them.

+/*	mmx.h
+
+	MultiMedia eXtensions GCC interface library for IA32.
+
+	To use this library, simply include this header file
+	and compile with GCC.  You MUST have inlining enabled
+	in order for mmx_ok() to work; this can be done by
+	simply using -O on the GCC command line.
+
+	Compiling with -DMMX_TRACE will cause detailed trace
+	output to be sent to stderr for each mmx operation.
+	This adds lots of code, and obviously slows execution to
+	a crawl, but can be very useful for debugging.
+
+	THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY
+	EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT
+	LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY
+	AND FITNESS FOR ANY PARTICULAR PURPOSE.
+
+	1997-98 by H. Dietz and R. Fisher
+
+ History:
+	97-98*	R.Fisher	Early versions
+	980501	R.Fisher	Original Release
+	980611*	H.Dietz		Rewrite, correctly implementing inlines, and
+		R.Fisher	 including direct register accesses.
+	980616	R.Fisher	Release of 980611 as 980616.
+	980714	R.Fisher	Minor corrections to Makefile, etc.
+	980715	R.Fisher	mmx_ok() now prevents optimizer from using
+				 clobbered values.
+				mmx_ok() now checks if cpuid instruction is
+				 available before trying to use it.
+	980726*	R.Fisher	mm_support() searches for AMD 3DNow, Cyrix
+				 Extended MMX, and standard MMX.  It returns a
+				 value which is positive if any of these are
+				 supported, and can be masked with constants to
+				 see which.  mmx_ok() is now a call to this
+	980726*	R.Fisher	Added i2r support for shift functions
+	980919	R.Fisher	Fixed AMD extended feature recognition bug.
+	980921	R.Fisher	Added definition/check for _MMX_H.
+				Added "float s[2]" to mmx_t for use with
+				  3DNow and EMMX.  So same mmx_t can be used.
+	981013	R.Fisher	Fixed cpuid function 1 bug (looked at wrong reg)
+				Fixed psllq_i2r error in mmxtest.c
+
+	* Unreleased (internal or interim) versions
+
+ Notes:
+	It appears that the latest gas has the pand problem fixed, therefore
+	  I'll undefine BROKEN_PAND by default.
+	String compares may be quicker than the multiple test/jumps in vendor
+	  test sequence in mmx_ok(), but I'm not concerned with that right now.
+
+ Acknowledgments:
+	Jussi Laako for pointing out the errors ultimately found to be
+	  connected to the failure to notify the optimizer of clobbered values.
+	Roger Hardiman for reminding us that CPUID isn't everywhere, and that
+	  someone may actually try to use this on a machine without CPUID.
+	  Also for suggesting code for checking this.
+	Robert Dale for pointing out the AMD recognition bug.
+	Jimmy Mayfield and Carl Witty for pointing out the Intel recognition
+	  bug.
+	Carl Witty for pointing out the psllq_i2r test bug.

+ * 
+ * For the most part, data is just copied from \c depth_bits, \c stencil_bits,
+ * \c db_modes, and \c visType into each \c __GLcontextModes element.
+ * However, the meanings of \c fb_format and \c fb_type require further
+ * explanation.  The \c fb_format specifies which color components are in
+ * each pixel and what the default order is.  For example, \c GL_RGB specifies
+ * that red, green, blue are available and red is in the "most significant"
+ * position and blue is in the "least significant".  The \c fb_type specifies
+ * the bit sizes of each component and the actual ordering.  For example, if
+ * \c GL_UNSIGNED_SHORT_5_6_5_REV is specified with \c GL_RGB, bits [15:11]
+ * are the blue value, bits [10:5] are the green value, and bits [4:0] are
+ * the red value.
+ * 
+ * One sublte issue is the combination of \c GL_RGB  or \c GL_BGR and either
+ * of the \c GL_UNSIGNED_INT_8_8_8_8 modes.  The resulting mask values in the
+ * \c __GLcontextModes structure is \b identical to the \c GL_RGBA or
+ * \c GL_BGRA case, except the \c alphaMask is zero.  This means that, as
+ * far as this routine is concerned, \c GL_RGB with \c GL_UNSIGNED_INT_8_8_8_8
+ * still uses 32-bits.
+ *
+ * If in doubt, look at the tables used in the function.
+ * 
+ * \param ptr_to_modes  Pointer to a pointer to a linked list of
+ *                      \c __GLcontextModes.  Upon completion, a pointer to
+ *                      the next element to be process will be stored here.
+ *                      If the function fails and returns \c GL_FALSE, this

+ *                      \c GL_UNSIGNED_SHORT_5_6_5, 
+ *                      \c GL_UNSIGNED_SHORT_5_6_5_REV,

+ * \param depth_bits    Array of depth buffer sizes to be exposed.
+ * \param stencil_bits  Array of stencil buffer sizes to be exposed.
+ * \param num_depth_stencil_bits  Number of entries in both \c depth_bits and
+ *                      \c stencil_bits.
+ * \param db_modes      Array of buffer swap modes.  If an element has a
+ *                      value of \c GLX_NONE, then it represents a
+ *                      single-buffered mode.  Other valid values are
+ *                      \c GLX_SWAP_EXCHANGE_OML, \c GLX_SWAP_COPY_OML, and
+ *                      \c GLX_SWAP_UNDEFINED_OML.  See the
+ *                      GLX_OML_swap_method extension spec for more details.
+ * \param num_db_modes  Number of entries in \c db_modes.
+ * \param visType       GLX visual type.  Usually either \c GLX_TRUE_COLOR or
+ *                      \c GLX_DIRECT_COLOR.
+ * 
+ * \returns
+ * \c GL_TRUE on success or \c GL_FALSE on failure.  Currently the only
+ * cause of failure is a bad parameter (i.e., unsupported \c fb_format or
+ * \c fb_type).
+ * 
+ * \todo
+ * There is currently no way to support packed RGB modes (i.e., modes with
+ * exactly 3 bytes per pixel) or floating-point modes.  This could probably
+ * be done by creating some new, private enums with clever names likes
+ * \c GL_UNSIGNED_3BYTE_8_8_8, \c GL_4FLOAT_32_32_32_32, 
+ * \c GL_4HALF_16_16_16_16, etc.  We can cross that bridge when we come to it.

+ * ioctl that returns a 64-bit count (at least not on 32-bit platforms).
+ * However, this function exists to support a GLX function that requires

+ * hackery at the end of this function to make the 32-bit count act like
+ * a 64-bit count.  There are still some cases where this will break, but

+ *                    means to use the glXWaitVideoSyncSGI() behavior.
+ * \param divisor     MSC divisor if \c target_msc is already reached.
+ * \param remainder   Desired MSC remainder if \c target_msc is already
+ *                    reached.

+ * DESCRIPTION
+ *
+ * This file contains a straightforward implementation of a fixed-sized
+ * hash table using self-organizing linked lists [Knuth73, pp. 398-399] for
+ * collision resolution.  There are two potentially interesting things
+ * about this implementation:
+ *
+ * 1) The table is power-of-two sized.  Prime sized tables are more
+ * traditional, but do not have a significant advantage over power-of-two
+ * sized table, especially when double hashing is not used for collision
+ * resolution.
+ *
+ * 2) The hash computation uses a table of random integers [Hanson97,
+ * pp. 39-41].
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * With a table size of 512, the current implementation is sufficient for a
+ * few hundred keys.  Since this is well above the expected size of the
+ * tables for which this implementation was designed, the implementation of
+ * dynamic hash tables was postponed until the need arises.  A common (and
+ * naive) approach to dynamic hash table implementation simply creates a
+ * new hash table when necessary, rehashes all the data into the new table,
+ * and destroys the old table.  The approach in [Larson88] is superior in
+ * two ways: 1) only a portion of the table is expanded when needed,
+ * distributing the expansion cost over several insertions, and 2) portions
+ * of the table can be locked, enabling a scalable thread-safe
+ * implementation.

+ *
+ * DESCRIPTION
+ *
+ * This file contains a simple, straightforward implementation of the Park
+ * & Miller "Minimal Standard" PRNG [PM88, PMS93], which is a Lehmer
+ * multiplicative linear congruential generator (MLCG) with a period of
+ * 2^31-1.
+ *
+ * This implementation is intended to provide a reliable, portable PRNG
+ * that is suitable for testing a hash table implementation and for
+ * implementing skip lists.
+ *
+ * FUTURE ENHANCEMENTS
+ *
+ * If initial seeds are not selected randomly, two instances of the PRNG
+ * can be correlated.  [Knuth81, pp. 32-33] describes a shuffling technique
+ * that can eliminate this problem.
+ *
+ * If PRNGs are used for simulation, the period of the current
+ * implementation may be too short.  [LE88] discusses methods of combining
+ * MLCGs to produce much longer periods, and suggests some alternative
+ * values for A and M.  [LE90 and Sch92] also provide information on
+ * long-period PRNGs.

+/* FFB fog support:
+ *
+ * There are two levels of support for FOG in the Creator3D series.
+ * Both involve a depth cue unit and 1 or 4 slope factors and scales
+ * for varying the pixel intensity.
+ *
+ * Chips prior to FFB2 only have a single set of such settings, FFB2
+ * and later have 4 settings.
+ *
+ * The basic depth cueing equation is:
+ *
+ *	C_final = dcsf(z) * C_orig + (1 - dcsf(z)) * C_fog
+ *
+ * 	C_final	--	The final color passed to blend unit or frame
+ *			buffer (if blending is disabled).
+ *
+ *	C_orig	--	The color we start with, which comes either from
+ *			the raster processor or cpu writes to the smart
+ *			framebuffer aperture.
+ *
+ *	C_fog	--	This is the "fog" color, ie. the desired color
+ *			at the deepest Z.
+ *
+ *	dcsf(z)	--	The depth cue scale as a function of Z.
+ *
+ * With pre-FFB2 chips there are four parameters to control the depth
+ * cue scaling.  Here is a diagram:
+ *
+ *		   1.0	-------------
+ *			|   |   |   |
+ *			|   |   |   |
+ *		Sfront	XXXXX---+---+
+ *			|   |X  |   |
+ *	dcsf(z)		|   | X |   |
+ *			|   |  X|   |
+ *		Sback	+---+---XXXXX
+ *			|   |   |   |
+ *		   0.0	-------------
+ *			0.0 Zf  Zb 1.0
+ *
+ *			      z
+ * Therefore:
+ *
+ *	for Zf < z < Zb
+ *
+ *		dcsf(z) = Sback + ((Sfront - Sback) / (Zf - Zb)) * (Zb - z)
+ *
+ *	for z <= Zf
+ *
+ *		dcsf(z) = Sfront
+ *
+ *	for z >= Zb
+ *
+ *		dcsf(z) = Sback
+ *
+ * With FFB2 and later, 3 more slope regions are provided, the first of
+ * them starts at the end of the region defined above and ends at a
+ * specified depth value, the next slop region starts there and ends
+ * at the next specified depth value, and so on.  Each of the 3 slope
+ * regions also have scale and slope settings of their own.
+ *
+ * The C_fog color is programmed into the alpha blending unit color1
+ * and color2 registers as follows:
+ *
+ *	color1:		-(C_fog)
+ *	color2:		C_fog - bg
+ *
+ * If alpha blending is disabled, the bg factor is zero.  Note that
+ * the alpha blending color registers specify each of the RGB values
+ * as 9 bit 1:8 signed numbers in the range -1.00 to 0.ff inclusive.
+ * (ie. 0x100 == -1.00 and 0x0ff == +0.ff)

+ * Looking at i830_3d_regs.h, it seems the i830 can do part of
+ * GL_ATI_texture_env_combine3.  It can handle using \c GL_ONE and
+ * \c GL_ZERO as combine inputs (which the code already supports).  It can
+ * also handle the \c GL_MODULATE_ADD_ATI mode.  Is it worth investigating
+ * partial support for the extension?
+ * 
+ * \todo
+ * Some thought needs to be put into the way combiners work.  The driver
+ * treats the hardware as if there's a specific combine unit tied to each
+ * texture unit.  That's why there's the special case for a disabled texture
+ * unit.  That's not the way the hardware works.  In reality, there are 4
+ * texture units and four general instruction slots.  Each instruction slot
+ * can use any texture as an input.  There's no need for this wierd "no-op"
+ * stuff.  If texture units 0 and 3 are enabled, the  instructions to combine
+ * them should be in slots 0 and 1, not 0 and 3 with two no-ops inbetween.

+   /* The G200 only has the ability to use 5 mipmap levels (including the
+    * base level).  The G400 does not have this restriction, but it still
+    * only has 5 offset pointers in the hardware.  The trick on the G400 is
+    * upto the first 4 offset pointers point to mipmap levels.  The last
+    * offset pointer tells how large the preceeding mipmap is.  This value is
+    * then used to determine where the remaining mipmaps are.
+    * 
+    * For example, if the first offsets[0] through offsets[2] are used as
+    * pointers, then offset[3] will be the size of the mipmap pointed to by
+    * offsets[2].  So mipmap level 3 will be at (offsets[2]+offsets[3]).  For
+    * each successive mipmap level, offsets[3] is divided by 4 and added to
+    * the previous address.  So mipmap level 4 will be at 
+    * (offsets[2]+offsets[3]+(offsets[3] / 4)).
+    * 
+    * The last pointer is selected by setting TO_texorgoffsetsel in its
+    * pointer.  In the previous example, offset[2] would have
+    * TO_texorgoffsetsel or'ed in before writing it to the hardware.
+    * 
+    * In the current driver all of the mipmaps are packed together linearly
+    * with mipmap level 0.  Therefore offsets[0] points to the base of the
+    * texture (and has TO_texorgoffsetsel or'ed in), and offsets[1] is the
+    * size of the base texture.
+    *
+    * There is a possible optimization available here.  At times the driver
+    * may not be able to allocate a single block of memory for the complete
+    * texture without ejecting some other textures from memory.  It may be
+    * possible to put some of the lower mipmap levels (i.e., the larger
+    * mipmaps) in memory separate from the higher levels.
+    *
+    * The implementation should be fairly obvious, but getting "right" would
+    * likely be non-trivial.  A first allocation for the entire texture would
+    * be attempted with a flag that says "don't eject other textures."  If
+    * that failed, an additional allocation would be attmpted for just the
+    * base map.  The process would repeat with the block of lower maps.  The
+    * tricky parts would be in detecting when some of the levels had been
+    * ejected from texture memory by other textures and preventing the
+    * 4th allocation (for all the smallest mipmap levels) from kicking out
+    * any of the first three.
+    * 
+    * This array holds G400_TEX_MAXLEVELS pointers to remove an if-statement
+    * in a loop in mgaSetTexImages.  Values past G200_TEX_MAXLEVELS are not

+//
+// The basic functional block seems to be one MAD for each color and alpha,
+// and an adder that adds all components after the MUL.
+//  - ADD, MUL, MAD etc.: use MAD with appropriate neutral operands
+//  - DP4: Use OUTC_DP4, OUTA_DP4
+//  - DP3: Use OUTC_DP3, OUTA_DP4, appropriate alpha operands
+//  - DPH: Use OUTC_DP4, OUTA_DP4, appropriate alpha operands
+//  - CMP: If ARG2 < 0, return ARG1, else return ARG0
+//  - FLR: use FRC+MAD
+//  - XPD: use MAD+MAD
+//  - SGE, SLT: use MAD+CMP
+//  - RSQ: use ABS modifier for argument
+//  - Use OUTC_REPL_ALPHA to write results of an alpha-only operation (e.g. RCP)
+//    into color register
+//  - apparently, there's no quick DST operation
+//  - fglrx set FPI2_UNKNOWN_31 on a "MAD fragment.color, tmp0, tmp1, tmp2"
+//  - fglrx set FPI2_UNKNOWN_31 on a "MAX r2, r1, c0"
+//  - fglrx once set FPI0_UNKNOWN_31 on a "FRC r1, r1"
+//
+// Operand selection
+// First stage selects three sources from the available registers and
+// constant parameters. This is defined in INSTR1 (color) and INSTR3 (alpha).
+// fglrx sorts the three source fields: Registers before constants,
+// lower indices before higher indices; I do not know whether this is necessary.
+// fglrx fills unused sources with "read constant 0"
+// According to specs, you cannot select more than two different constants.
+//
+// Second stage selects the operands from the sources. This is defined in
+// INSTR0 (color) and INSTR2 (alpha). You can also select the special constants
+// zero and one.
+// Swizzling and negation happens in this stage, as well.
+//
+// Important: Color and alpha seem to be mostly separate, i.e. their sources
+// selection appears to be fully independent (the register storage is probably
+// physically split into a color and an alpha section).
+// However (because of the apparent physical split), there is some interaction
+// WRT swizzling. If, for example, you want to load an R component into an
+// Alpha operand, this R component is taken from a *color* source, not from
+// an alpha source. The corresponding register doesn't even have to appear in
+// the alpha sources list. (I hope this alll makes sense to you)
+//
+// Destination selection
+// The destination register index is in FPI1 (color) and FPI3 (alpha) together

+ * Because the Linear Frame Buffer is not necessarily aligned

+ *   +-----------------------------------+xxxxxxxxxxxxxxxxxxx+
+ *
+ * You can only reliably read and write legal locations.  Reads
+ * and writes from the Forbidden Zone will return undefined values,
+ * and may cause segmentation faults.
+ *
+ * Now, the depth buffer may not end up in a location such each
+ * scan line is an LFB line.  For example, the depth buffer may
+ * look like this:
+ *
+ *    wrapped               ordinary.

+ * allocated at the beginning of LFB memory, and so it is always
+ * properly aligned with the LFB stride.)
+ *
+ * We call the beginning of the line (which is the rightmost
+ * part of the depth line in the picture above) the *ordinary* part
+ * of the scanline, and the end of the line (which is the
+ * leftmost part, one line below) the *wrapped* part of the scanline.

+ *           depthBufferOffset&(info.strideInBytes)
+ *     is then the offset (in bytes) from the beginining of (any)

+  * 2. when both DEPTH and ALPHA are enabled, depth should win. However, it is
+  *    not clear whether 15bpp and 32bpp require AUX alpha buffer. Furthermore,
+  *    alpha buffering is required only if destination alpha is used in alpha
+  *    blending; alpha blending modes that do not use destination alpha can be
+  *    used w/o alpha buffer.
+  * 3. `alphaBits' is what we can provide
+  *    `alphaSize' is what app requests
+  *    if we cannot provide enough bits for alpha buffer, we should fallback to
+  *    SW alpha. However, setting `alphaBits' to `alphaSize' might confuse some

+DESCRIPTION 'Mesa (OpenGL work-alike) for Win32'
+VERSION 6.0
+;
+; Module definition file for Mesa (OPENGL32.DLL)
+;
+; Note: The OpenGL functions use the STDCALL
+; function calling convention.  Microsoft's
+; OPENGL32 uses this convention and so must the
+; Mesa OPENGL32 so that the Mesa DLL can be used
+; as a drop-in replacement.
+;
+; The linker exports STDCALL entry points with
+; 'decorated' names; e.g., _glBegin@0, where the
+; trailing number is the number of bytes of 
+; parameter data pushed onto the stack.  The
+; callee is responsible for popping this data
+; off the stack, usually via a RETF n instruction.
+;
+; However, the Microsoft OPENGL32.DLL does not export
+; the decorated names, even though the calling convention
+; is STDCALL.  So, this module definition file is
+; needed to force the Mesa OPENGL32.DLL to export the
+; symbols in the same manner as the Microsoft DLL.
+; Were it not for this problem, this file would not
+; be needed (for the gl* functions) since the entry
+; points are compiled with dllexport declspec.
+;
+; However, this file is still needed to export "internal"
+; Mesa symbols for the benefit of the OSMESA32.DLL.

+ * This file contains the implementations of all the XMesa* functions.

+ * NOTES:
+ *
+ * The window coordinate system origin (0,0) is in the lower-left corner
+ * of the window.  X11's window coordinate origin is in the upper-left
+ * corner of the window.  Therefore, most drawing functions in this
+ * file have to flip Y coordinates.
+ *
+ * Define USE_XSHM in the Makefile with -DUSE_XSHM if you want to compile
+ * in support for the MIT Shared Memory extension.  If enabled, when you
+ * use an Ximage for the back buffer in double buffered mode, the "swap"
+ * operation will be faster.  You must also link with -lXext.
+ *
+ * Byte swapping:  If the Mesa host and the X display use a different
+ * byte order then there's some trickiness to be aware of when using
+ * XImages.  The byte ordering used for the XImage is that of the X
+ * display, not the Mesa host.
+ * The color-to-pixel encoding for True/DirectColor must be done
+ * according to the display's visual red_mask, green_mask, and blue_mask.
+ * If XPutPixel is used to put a pixel into an XImage then XPutPixel will
+ * do byte swapping if needed.  If one wants to directly "poke" the pixel
+ * into the XImage's buffer then the pixel must be byte swapped first.  In
+ * Mesa, when byte swapping is needed we use the PF_TRUECOLOR pixel format
+ * and use XPutPixel everywhere except in the implementation of
+ * glClear(GL_COLOR_BUFFER_BIT).  We want this function to be fast so
+ * instead of using XPutPixel we "poke" our values after byte-swapping
+ * the clear pixel value if needed.

+ *      lines)
+ *   3. different color per-pixel or same color for all pixels
+ *
+ * Furthermore, the X driver needs to support rendering to 3 possible
+ * "buffers", usually one, but sometimes two at a time:
+ *   1. The front buffer as an X window
+ *   2. The back buffer as a Pixmap
+ *   3. The back buffer as an XImage
+ *
+ * Finally, if the back buffer is an XImage, we can avoid using XPutPixel and
+ * optimize common cases such as 24-bit and 8-bit modes.
+ *
+ * By multiplication, there's at least 48 possible combinations of the above.
+ *
+ * Below are implementations of the most commonly used combinations.  They are
+ * accessed through function pointers which get initialized here and are used
+ * directly from the Mesa library.  The 8 function pointers directly correspond
+ * to the first 3 cases listed above.
+ *
+ *
+ * The function naming convention is:
+ *
+ *   [put|get]_[mono]_[row|values]_[format]_[pixmap|ximage]
+ *
+ * New functions optimized for specific cases can be added without too much
+ * trouble.  An example might be the 24-bit TrueColor mode 8A8R8G8B which is
+ * found on IBM RS/6000 X servers.

+ * This file manages the OpenGL API dispatch layer.
+ * The dispatch table (struct _glapi_table) is basically just a list
+ * of function pointers.
+ * There are functions to set/get the current dispatch table for the
+ * current thread and to manage registration/dispatch of dynamically
+ * added extension functions.
+ *
+ * It's intended that this file and the other glapi*.[ch] files are
+ * flexible enough to be reused in several places:  XFree86, DRI-
+ * based libGL.so, and perhaps the SGI SI.
+ *
+ * NOTE: There are no dependencies on Mesa in this code.
+ *
+ * Versions (API changes):
+ *   2000/02/23  - original version for Mesa 3.3 and XFree86 4.0
+ *   2001/01/16  - added dispatch override feature for Mesa 3.5
+ *   2002/06/28  - added _glapi_set_warning_func(), Mesa 4.1.
+ *   2002/10/01  - _glapi_get_proc_address() will now generate new entrypoints
+ *                 itself (using offset ~0).  _glapi_add_entrypoint() can be
+ *                 called afterward and it'll fill in the correct dispatch
+ *                 offset.  This allows DRI libGL to avoid probing for DRI
+ *                 drivers!  No changes to the public glapi interface.

+ * \name Current dispatch and current context control variables
+ *
+ * Depending on whether or not multithreading is support, and the type of
+ * support available, several variables are used to store the current context
+ * pointer and the current dispatch table pointer.  In the non-threaded case,
+ * the variables \c _glapi_Dispatch and \c _glapi_Context are used for this
+ * purpose.
+ *
+ * In the "normal" threaded case, the variables \c _glapi_Dispatch and
+ * \c _glapi_Context will be \c NULL if an application is detected as being
+ * multithreaded.  Single-threaded applications will use \c _glapi_Dispatch
+ * and \c _glapi_Context just like the case without any threading support.
+ * When \c _glapi_Dispatch and \c _glapi_Context are \c NULL, the thread state
+ * data \c _gl_DispatchTSD and \c ContextTSD are used.  Drivers and the
+ * static dispatch functions access these variables via \c _glapi_get_dispatch
+ * and \c _glapi_get_context.
+ *
+ * There is a race condition in setting \c _glapi_Dispatch to \c NULL.  It is
+ * possible for the original thread to be setting it at the same instant a new
+ * thread, perhaps running on a different processor, is clearing it.  Because
+ * of that, \c ThreadSafe, which can only ever be changed to \c GL_TRUE, is
+ * used to determine whether or not the application is multithreaded.
+ * 
+ * In the TLS case, the variables \c _glapi_Dispatch and \c _glapi_Context are
+ * hardcoded to \c NULL.  Instead the TLS variables \c _glapi_tls_Dispatch and
+ * \c _glapi_tls_Context are used.  Having \c _glapi_Dispatch and
+ * \c _glapi_Context be hardcoded to \c NULL maintains binary compatability
+ * between TLS enabled loaders and non-TLS DRI drivers.

+ * This file is a template which generates the OpenGL API entry point
+ * functions.  It should be included by a .c file which first defines
+ * the following macros:
+ *   KEYWORD1 - usually nothing, but might be __declspec(dllexport) on Win32
+ *   KEYWORD2 - usually nothing, but might be __stdcall on Win32
+ *   NAME(n)  - builds the final function name (usually add "gl" prefix)
+ *   DISPATCH(func, args, msg) - code to do dispatch of named function.
+ *                               msg is a printf-style debug message.
+ *   RETURN_DISPATCH(func, args, msg) - code to do dispatch with a return value
+ *
+ * Here is an example which generates the usual OpenGL functions:
+ *   #define KEYWORD1
+ *   #define KEYWORD2
+ *   #define NAME(func)  gl##func
+ *   #define DISPATCH(func, args, msg)                           \
+ *          struct _glapi_table *dispatch = CurrentDispatch;     \
+ *          (*dispatch->func) args
+ *   #define RETURN DISPATCH(func, args, msg)                    \

+ * There are three Mesa data types which are meant to be used by device

+ * - GLcontext: this contains the Mesa rendering state
+ * - GLvisual:  this describes the color buffer (RGB vs. ci), whether or not
+ *   there's a depth buffer, stencil buffer, etc.
+ * - GLframebuffer:  contains pointers to the depth buffer, stencil buffer,
+ *   accum buffer and alpha buffers.
+ *
+ * These types should be encapsulated by corresponding device driver
+ * data types.  See xmesa.h and xmesaP.h for an example.
+ *
+ * In OOP terms, GLcontext, GLvisual, and GLframebuffer are base classes
+ * which the device driver must derive from.

+ * The following functions create and destroy these data types.

+/**
+ * \file imports.c
+ * Standard C library function wrappers.
+ * 
+ * Imports are services which the device driver or window system or
+ * operating system provides to the core renderer.  The core renderer (Mesa)
+ * will call these functions in order to do memory allocation, simple I/O,
+ * etc.
+ *
+ * Some drivers will want to override/replace this file with something
+ * specialized, but that'll be rare.
+ *
+ * Eventually, I want to move roll the glheader.h file into this.
+ *
+ * The OpenGL SI's __GLimports structure allows per-context specification of
+ * replacements for the standard C lib functions.  In practice that's probably
+ * never needed; compile-time replacements are far more likely.
+ *
+ * The _mesa_*() functions defined here don't in general take a context
+ * parameter.  I guess we can change that someday, if need be.

+
+         This isn't a bad approximation of 1/sqrt.  The maximum difference from
+         1/sqrt will be around .06.  After three Newton-Raphson iterations, the
+         maximum difference is less than 4.5e-8.  (Which is actually close
+         enough to make the following bias academic...)
+
+         To get a better approximation you can add a bias to the magic
+         number.  For example, if you subtract 1/2 of the maximum difference in
+         the first approximation (.03), you will get the following function:

+         (The 3.76 to 4 range is where the result is < .5.)
+
+         This is the closest possible initial approximation, but with a maximum
+         error of 8e-11 after three NR iterations, it is still not perfect.  If
+         you subtract 0.0332281 instead of .03, the maximum error will be
+         2.5e-11 after three NR iterations, which should be about as close as
+         is possible.

+ * Horner scheme for Bezier curves
+ *
+ * Bezier curves can be computed via a Horner scheme.
+ * Horner is numerically less stable than the de Casteljau
+ * algorithm, but it is faster. For curves of degree n
+ * the complexity of Horner is O(n) and de Casteljau is O(n^2).
+ * Since stability is not important for displaying curve
+ * points I decided to use the Horner scheme.
+ *
+ * A cubic Bezier curve with control points b0, b1, b2, b3 can be
+ * written as
+ *
+ *        (([3]        [3]     )     [3]       )     [3]
+ * c(t) = (([0]*s*b0 + [1]*t*b1)*s + [2]*t^2*b2)*s + [3]*t^2*b3
+ *
+ *                                           [n]
+ * where s=1-t and the binomial coefficients [i]. These can
+ * be computed iteratively using the identity:
+ *
+ * [n]               [n  ]             [n]
+ * [i] = (n-i+1)/i * [i-1]     and     [0] = 1

+ * Horner scheme for Bezier curves
+ *
+ * Bezier curves can be computed via a Horner scheme.
+ * Horner is numerically less stable than the de Casteljau
+ * algorithm, but it is faster. For curves of degree n
+ * the complexity of Horner is O(n) and de Casteljau is O(n^2).
+ * Since stability is not important for displaying curve
+ * points I decided to use the Horner scheme.
+ *
+ * A cubic Bezier curve with control points b0, b1, b2, b3 can be
+ * written as
+ *
+ *        (([3]        [3]     )     [3]       )     [3]
+ * c(t) = (([0]*s*b0 + [1]*t*b1)*s + [2]*t^2*b2)*s + [3]*t^2*b3
+ *
+ *                                           [n]
+ * where s=1-t and the binomial coefficients [i]. These can
+ * be computed iteratively using the identity:
+ *
+ * [n]               [n  ]             [n]
+ * [i] = (n-i+1)/i * [i-1]     and     [0] = 1

+       *  like so:  Rz * Ry * T * Ry' * Rz'.  T is the final rotation
+       *  (which is about the X-axis), and the two composite transforms
+       *  Ry' * Rz' and Rz * Ry are (respectively) the rotations necessary
+       *  from the arbitrary axis to the X-axis then back.  They are
+       *  all elementary rotations.
+       *
+       *  Rz' is a rotation about the Z-axis, to bring the axis vector
+       *  into the x-z plane.  Then Ry' is applied, rotating about the
+       *  Y-axis to bring the axis vector parallel with the X-axis.  The
+       *  rotation about the X-axis is then performed.  Ry and Rz are
+       *  simply the respective inverse transforms to bring the arbitrary
+       *  axis back to it's original orientation.  The first transforms
+       *  Rz' and Ry' are considered inverses, since the data from the
+       *  arbitrary axis gives you info on how to get to it, not how
+       *  to get away from it, and an inverse must be applied.
+       *
+       *  The basic calculation used is to recognize that the arbitrary
+       *  axis vector (x, y, z), since it is of unit length, actually
+       *  represents the sines and cosines of the angles to rotate the
+       *  X-axis to the same orientation, with theta being the angle about
+       *  Z and phi the angle about Y (in the order described above)
+       *  as follows:
+       *
+       *  cos ( theta ) = x / sqrt ( 1 - z^2 )
+       *  sin ( theta ) = y / sqrt ( 1 - z^2 )
+       *
+       *  cos ( phi ) = sqrt ( 1 - z^2 )
+       *  sin ( phi ) = z
+       *
+       *  Note that cos ( phi ) can further be inserted to the above
+       *  formulas:
+       *
+       *  cos ( theta ) = x / cos ( phi )
+       *  sin ( theta ) = y / sin ( phi )
+       *
+       *  ...etc.  Because of those relations and the standard trigonometric
+       *  relations, it is pssible to reduce the transforms down to what
+       *  is used below.  It may be that any primary axis chosen will give the
+       *  same results (modulo a sign convention) using thie method.
+       *
+       *  Particularly nice is to notice that all divisions that might
+       *  have caused trouble when parallel to certain planes or
+       *  axis go away with care paid to reducing the expressions.
+       *  After checking, it does perform correctly under all cases, since
+       *  in all the cases of division where the denominator would have
+       *  been zero, the numerator would have been zero as well, giving
+       *  the expected result.

+/* KW: Clip functions now do projective divide as well.  The projected
+ * coordinates are very useful to us because they let us cull
+ * backfaces and eliminate vertices from lighting, fogging, etc
+ * calculations.  Despite the fact that this divide could be done one
+ * day in hardware, we would still have a reason to want to do it here
+ * as long as those other calculations remain in software.
+ *
+ * Clipping is a convenient place to do the divide on x86 as it should be
+ * possible to overlap with integer outcode calculations.
+ *
+ * There are two cases where we wouldn't want to do the divide in cliptest:
+ *    - When we aren't clipping.  We still might want to cull backfaces
+ *      so the divide should be done elsewhere.  This currently never
+ *      happens.
+ *
+ *    - When culling isn't likely to help us, such as when the GL culling
+ *      is disabled and we not lighting or are only lighting
+ *      one-sided.  In this situation, backface determination provides
+ *      us with no useful information.  A tricky case to detect is when
+ *      all input data is already culled, although hopefully the
+ *      application wouldn't turn on culling in such cases.
+ *
+ * We supply a buffer to hold the [x/w,y/w,z/w,1/w] values which
+ * are the result of the projection.  This is only used in the
+ * 4-vector case - in other cases, we just use the clip coordinates
+ * as the projected coordinates - they are identical.
+ *
+ * This is doubly convenient because it means the Win[] array is now
+ * of the same stride as all the others, so I can now turn map_vertices
+ * into a straight-forward matrix transformation, with asm acceleration
+ * automatically available.

+ *       + For absolute arrays, store a bitmap of accesses
+ *       + For single parameters, store an access flag
+ *       + After parsing, make a parameter cleanup and merging pass, where
+ *           relative arrays are layed out first, followed by abs arrays, and
+ *           finally single state.
+ *       + Remap offsets for param src and dst registers
+ *       + Now we can properly count parameter usage
+ *
+ *    - Multiple state binding errors in param arrays (see spec, just before
+ *         section 2.14.3.3)
+ *    - grep for XXX
+ *
+ *    Mesa Stuff
+ *    -----------------------------------------------------
+ *    - User clipping planes vs. PositionInvariant
+ *    - Is it sufficient to just multiply by the mvp to transform in the
+ *        PositionInvariant case? Or do we need something more involved?
+ *
+ *    - vp_src swizzle is GLubyte, fp_src swizzle is GLuint
+ *    - fetch state listed in program_parameters list
+ *       + WTF should this go???
+ *       + currently in nvvertexec.c and s_nvfragprog.c
+ *
+ *    - allow for multiple address registers (and fetch address regs properly)
+ *
+ *    Cosmetic Stuff
+ *    -----------------------------------------------------
+ * 	- remove any leftover unused grammer.c stuff (dict_ ?)
+ * 	- fix grammer.c error handling so its not static
+ * 	- #ifdef around stuff pertaining to extentions
+ *
+ *    Outstanding Questions:
+ *    -----------------------------------------------------
+ *    - ARB_matrix_palette / ARB_vertex_blend -- not supported
+ *      what gets hacked off because of this:
+ *       + VERTEX_ATTRIB_MATRIXINDEX
+ *       + VERTEX_ATTRIB_WEIGHT
+ *       + MATRIX_MODELVIEW
+ *       + MATRIX_PALETTE
+ *
+ *    - When can we fetch env/local params from their own register files, and
+ *      when to we have to fetch them into the main state register file?
+ *      (think arrays)
+ *
+ *    Grammar Changes:
+ *    -----------------------------------------------------

+- added #include "grammar_mesa.h"
+- removed grammar specific code part (it resides now in grammar.c)
+- added GL_ARB_fragment_program_shadow tokens
+- modified #include "arbparse_syn.h"
+- major changes inside _mesa_parse_arb_program()
+- check the program string for '\0' characters
+- copy the program string to a one-byte-longer location to have
+  it null-terminated
+- position invariance test (not writing to result.position) moved

+    INTRODUCTION
+    ------------
+
+    The task is to check the syntax of an input string. Input string is a stream of ASCII
+    characters terminated with a null-character ('\0'). Checking it using C language is
+    difficult and hard to implement without bugs. It is hard to maintain and make changes when
+    the syntax changes.
+
+    This is because of a high redundancy of the C code. Large blocks of code are duplicated with
+    only small changes. Even use of macros does not solve the problem because macros cannot
+    erase the complexity of the problem.
+
+    The resolution is to create a new language that will be highly oriented to our task. Once
+    we describe a particular syntax, we are done. We can then focus on the code that implements
+    the language. The size and complexity of it is relatively small than the code that directly
+    checks the syntax.
+
+    First, we must implement our new language. Here, the language is implemented in C, but it
+    could also be implemented in any other language. The code is listed below. We must take
+    a good care that it is bug free. This is simple because the code is simple and clean.
+
+    Next, we must describe the syntax of our new language in itself. Once created and checked
+    manually that it is correct, we can use it to check another scripts.
+
+    Note that our new language loading code does not have to check the syntax. It is because we
+    assume that the script describing itself is correct, and other scripts can be syntactically
+    checked by the former script. The loading code must only do semantic checking which leads us to
+    simple resolving references.
+
+    THE LANGUAGE
+    ------------
+
+    Here I will describe the syntax of the new language (further called "Synek"). It is mainly a
+    sequence of declarations terminated by a semicolon. The declaration consists of a symbol,
+    which is an identifier, and its definition. A definition is in turn a sequence of specifiers
+    connected with ".and" or ".or" operator. These operators cannot be mixed together in a one
+    definition. Specifier can be a symbol, string, character, character range or a special
+    keyword ".true" or ".false".
+
+    On the very beginning of the script there is a declaration of a root symbol and is in the form:
+        .syntax <root_symbol>;
+    The <root_symbol> must be on of the symbols in declaration sequence. The syntax is correct if
+    the root symbol evaluates to true. A symbol evaluates to true if the definition associated with
+    the symbol evaluates to true. Definition evaluation depends on the operator used to connect
+    specifiers in the definition. If ".and" operator is used, definition evaluates to true if and
+    only if all the specifiers evaluate to true. If ".or" operator is used, definition evalutes to
+    true if any of the specifiers evaluates to true. If definition contains only one specifier,
+    it is evaluated as if it was connected with ".true" keyword by ".and" operator.
+
+    If specifier is a ".true" keyword, it always evaluates to true.
+
+    If specifier is a ".false" keyword, it always evaluates to false. Specifier evaluates to false
+    when it does not evaluate to true.
+
+    Character range specifier is in the form:
+        '<first_character>' - '<second_character>'
+    If specifier is a character range, it evaluates to true if character in the stream is greater
+    or equal to <first_character> and less or equal to <second_character>. In that situation 
+    the stream pointer is advanced to point to next character in the stream. All C-style escape
+    sequences are supported although trigraph sequences are not. The comparisions are performed
+    on 8-bit unsigned integers.
+
+    Character specifier is in the form:
+        '<single_character>'
+    It evaluates to true if the following character range specifier evaluates to true:
+        '<single_character>' - '<single_character>'
+
+    String specifier is in the form:
+        "<string>"
+    Let N be the number of characters in <string>. Let <string>[i] designate i-th character in
+    <string>. Then the string specifier evaluates to true if and only if for i in the range [0, N)
+    the following character specifier evaluates to true:
+        '<string>[i]'
+    If <string>[i] is a quotation mark, '<string>[i]' is replaced with '\<string>[i]'.
+
+    Symbol specifier can be optionally preceded by a ".loop" keyword in the form:
+        .loop <symbol>                  (1)
+    where <symbol> is defined as follows:
+        <symbol> <definition>;          (2)
+    Construction (1) is replaced by the following code:
+        <symbol$1>
+    and declaration (2) is replaced by the following:
+        <symbol$1> <symbol$2> .or .true;
+        <symbol$2> <symbol> .and <symbol$1>;
+        <symbol> <definition>;
+
+    Synek supports also a register mechanizm. User can, in its SYN file, declare a number of
+    registers that can be accessed in the syn body. Each reg has its name and a default value.
+    The register is one byte wide. The C code can change the default value by calling
+    grammar_set_reg8() with grammar id, register name and a new value. As we know, each rule is
+    a sequence of specifiers joined with .and or .or operator. And now each specifier can be
+    prefixed with a condition expression in a form ".if (<reg_name> <operator> <hex_literal>)"
+    where <operator> can be == or !=. If the condition evaluates to false, the specifier
+    evaluates to .false. Otherwise it evalutes to the specifier.
+
+    ESCAPE SEQUENCES
+    ----------------
+
+    Synek supports all escape sequences in character specifiers. The mapping table is listed below.
+    All occurences of the characters in the first column are replaced with the corresponding
+    character in the second column.
+
+        Escape sequence         Represents
+    ------------------------------------------------------------------------------------------------
+        \a                      Bell (alert)
+        \b                      Backspace
+        \f                      Formfeed
+        \n                      New line
+        \r                      Carriage return
+        \t                      Horizontal tab
+        \v                      Vertical tab
+        \'                      Single quotation mark
+        \"                      Double quotation mark
+        \\                      Backslash
+        \?                      Literal question mark
+        \ooo                    ASCII character in octal notation
+        \xhhh                   ASCII character in hexadecimal notation
+    ------------------------------------------------------------------------------------------------
+
+    RAISING ERRORS
+    --------------
+
+    Any specifier can be followed by a special construction that is executed when the specifier
+    evaluates to false. The construction is in the form:
+        .error <ERROR_TEXT>
+    <ERROR_TEXT> is an identifier declared earlier by error text declaration. The declaration is
+    in the form:
+        .errtext <ERROR_TEXT> "<error_desc>"
+    When specifier evaluates to false and this construction is present, parsing is stopped
+    immediately and <error_desc> is returned as a result of parsing. The error position is also
+    returned and it is meant as an offset from the beggining of the stream to the character that
+    was valid so far. Example:
+
+        (**** syntax script ****)
+
+        .syntax program;
+        .errtext MISSING_SEMICOLON      "missing ';'"
+        program         declaration .and .loop space .and ';' .error MISSING_SEMICOLON .and
+                        .loop space .and '\0';
+        declaration     "declare" .and .loop space .and identifier;
+        space           ' ';
+
+        (**** sample code ****)
+
+        declare foo ,
+
+    In the example above checking the sample code will result in error message "missing ';'" and
+    error position 12. The sample code is not correct. Note the presence of '\0' specifier to
+    assure that there is no code after semicolon - only spaces.
+    <error_desc> can optionally contain identifier surrounded by dollar signs $. In such a case,
+    the identifier and dollar signs are replaced by a string retrieved by invoking symbol with
+    the identifier name. The starting position is the error position. The lenght of the resulting
+    string is the position after invoking the symbol.
+
+    PRODUCTION
+    ----------
+
+    Synek not only checks the syntax but it can also produce (emit) bytes associated with specifiers
+    that evaluate to true. That is, every specifier and optional error construction can be followed
+    by a number of emit constructions that are in the form:
+        .emit <parameter>
+    <paramater> can be a HEX number, identifier, a star * or a dollar $. HEX number is preceded by
+    0x or 0X. If <parameter> is an identifier, it must be earlier declared by emit code declaration
+    in the form:
+        .emtcode <identifier> <hex_number>
+
+    When given specifier evaluates to true, all emits associated with the specifier are output
+    in order they were declared. A star means that last-read character should be output instead
+    of constant value. Example:
+
+        (**** syntax script ****)
+
+        .syntax foobar;
+        .emtcode WORD_FOO       0x01
+        .emtcode WORD_BAR       0x02
+        foobar      FOO .emit WORD_FOO .or BAR .emit WORD_BAR .or .true .emit 0x00;
+        FOO         "foo" .and SPACE;
+        BAR         "bar" .and SPACE;
+        SPACE       ' ' .or '\0';
+
+        (**** sample text 1 ****)
+
+        foo
+
+        (**** sample text 2 ****)
+
+        foobar
+
+    For both samples the result will be one-element array. For first sample text it will be
+    value 1, for second - 0. Note that every text will be accepted because of presence of
+    .true as an alternative.
+
+    Another example:
+
+        (**** syntax script ****)
+
+        .syntax declaration;
+        .emtcode VARIABLE       0x01
+        declaration     "declare" .and .loop space .and
+                        identifier .emit VARIABLE .and          (1)
+                        .true .emit 0x00 .and                   (2)
+                        .loop space .and ';';
+        space           ' ' .or '\t';
+        identifier      .loop id_char .emit *;                  (3)
+        id_char         'a'-'z' .or 'A'-'Z' .or '_';
+
+        (**** sample code ****)
+
+        declare    fubar;
+
+    In specifier (1) symbol <identifier> is followed by .emit VARIABLE. If it evaluates to
+    true, VARIABLE constant and then production of the symbol is output. Specifier (2) is used
+    to terminate the string with null to signal when the string ends. Specifier (3) outputs
+    all characters that make declared identifier. The result of sample code will be the
+    following array:
+        { 1, 'f', 'u', 'b', 'a', 'r', 0 }
+
+    If .emit is followed by dollar $, it means that current position should be output. Current
+    position is a 32-bit unsigned integer distance from the very beginning of the parsed string to
+    first character consumed by the specifier associated with the .emit instruction. Current
+    position is stored in the output buffer in Little-Endian convention (the lowest byte comes
+    first).

+    adds a new regbyte named "vertex_blend" to the static list and initializes it to 0.
+    When the script is executed, this regbyte can be accessed by name for read and write. When a
+    particular regbyte is written, a new regbyte_ctx entry is added to the top of the regbyte_ctx
+    stack. The new entry contains information abot which regbyte it references and its new value.
+    When a given regbyte is accessed for read, the stack is searched top-down to find an
+    entry that references the regbyte. The first matching entry is used to return the current
+    value it holds. If no entry is found, the default value is returned.

+Thoughts on vertex program optimization:
+
+The obvious thing to do is to compile the vertex program into X86/SSE/3DNow!
+assembly code.  That will probably be a lot of work.
+
+Another approach might be to replace the vp_instruction->Opcode field with
+a pointer to a specialized C function which executes the instruction.
+In particular we can write functions which skip swizzling, negating,
+masking, relative addressing, etc. when they're not needed.
+
+For example:
+
+void simple_add( struct vp_instruction *inst )
+{
+   GLfloat *sum = machine->Registers[inst->DstReg.Register];
+   GLfloat *a = machine->Registers[inst->SrcReg[0].Register];
+   GLfloat *b = machine->Registers[inst->SrcReg[1].Register];
+   sum[0] = a[0] + b[0];
+   sum[1] = a[1] + b[1];
+   sum[2] = a[2] + b[2];
+   sum[3] = a[3] + b[3];
+}
+
+*/
+
+/*
+
+KW:
+
+A first step would be to 'vectorize' the programs in the same way as
+the normal transformation code in the tnl module.  Thus each opcode
+takes zero or more input vectors (registers) and produces one or more
+output vectors.
+
+These operations would intially be coded in C, with machine-specific
+assembly following, as is currently the case for matrix
+transformations in the math/ directory.  The preprocessing scheme for
+selecting simpler operations Brian describes above would also work
+here.
+
+This should give reasonable performance without excessive effort.

+	/* TODO
+	 *
+	 * 1) It would be nice if load/store double could be used
+	 *    at least for the matrix parts.  I think for the matrices
+	 *    it is safe, but for the vertices it probably is not due to
+	 *    things like glInterleavedArrays etc.
+	 *
+	 *    UPDATE: Trying this now in sparc_matrix.h -DaveM_990624
+	 *
+	 * 2) One extremely slick trick would be if we could enclose
+	 *    groups of xform calls on the same vertices such that
+	 *    we just load the matrix into f16-->f31 before the calls
+	 *    and then we would not have to do them here.  This may be
+	 *    tricky and not much of a gain though.

+ * Accumulation buffer notes
+ *
+ * Normally, accumulation buffer values are GLshorts with values in
+ * [-32767, 32767] which represent floating point colors in [-1, 1],
+ * as defined by the OpenGL specification.
+ *
+ * We optimize for the common case used for full-scene antialiasing:
+ *    // start with accum buffer cleared to zero
+ *    glAccum(GL_LOAD, w);   // or GL_ACCUM the first image
+ *    glAccum(GL_ACCUM, w);
+ *    ...
+ *    glAccum(GL_ACCUM, w);
+ *    glAccum(GL_RETURN, 1.0);
+ * That is, we start with an empty accumulation buffer and accumulate
+ * n images, each with weight w = 1/n.
+ * In this scenario, we can simply store unscaled integer values in
+ * the accum buffer instead of scaled integers.  We'll also keep track
+ * of the w value so when we do GL_RETURN we simply divide the accumulated
+ * values by n (n=1/w).
+ * This lets us avoid _many_ int->float->int conversions.

+ * Line Rasterizer Template
+ *
+ * This file is #include'd to generate custom line rasterizers.
+ *
+ * The following macros may be defined to indicate what auxillary information
+ * must be interplated along the line:
+ *    INTERP_Z        - if defined, interpolate Z values
+ *    INTERP_FOG      - if defined, interpolate FOG values
+ *    INTERP_RGBA     - if defined, interpolate RGBA values
+ *    INTERP_SPEC     - if defined, interpolate specular RGB values
+ *    INTERP_INDEX    - if defined, interpolate color index values
+ *    INTERP_TEX      - if defined, interpolate unit 0 texcoords
+ *    INTERP_MULTITEX - if defined, interpolate multi-texcoords
+ *
+ * When one can directly address pixels in the color buffer the following
+ * macros can be defined and used to directly compute pixel addresses during
+ * rasterization (see pixelPtr):
+ *    PIXEL_TYPE          - the datatype of a pixel (GLubyte, GLushort, GLuint)
+ *    BYTES_PER_ROW       - number of bytes per row in the color buffer
+ *    PIXEL_ADDRESS(X,Y)  - returns the address of pixel at (X,Y) where
+ *                          Y==0 at bottom of screen and increases upward.
+ *
+ * Similarly, for direct depth buffer access, this type is used for depth
+ * buffer addressing:
+ *    DEPTH_TYPE          - either GLushort or GLuint
+ *
+ * Optionally, one may provide one-time setup code
+ *    SETUP_CODE    - code which is to be executed once per line
+ *
+ * To actually "plot" each pixel the PLOT macro must be defined...
+ *    PLOT(X,Y) - code to plot a pixel.  Example:
+ *                if (Z < *zPtr) {
+ *                   *zPtr = Z;
+ *                   color = pack_rgb( FixedToInt(r0), FixedToInt(g0),
+ *                                     FixedToInt(b0) );
+ *                   put_pixel( X, Y, color );
+ *                }
+ *
+ * This code was designed for the origin to be in the lower-left corner.

+ * When one can directly address pixels in the color buffer the following
+ * macros can be defined and used to compute pixel addresses during
+ * rasterization (see pRow):
+ *    PIXEL_TYPE          - the datatype of a pixel (GLubyte, GLushort, GLuint)
+ *    BYTES_PER_ROW       - number of bytes per row in the color buffer
+ *    PIXEL_ADDRESS(X,Y)  - returns the address of pixel at (X,Y) where
+ *                          Y==0 at bottom of screen and increases upward.
+ *
+ * Similarly, for direct depth buffer access, this type is used for depth
+ * buffer addressing:
+ *    DEPTH_TYPE          - either GLushort or GLuint
+ *
+ * Optionally, one may provide one-time setup code per triangle:
+ *    SETUP_CODE    - code which is to be executed once per triangle
+ *    CLEANUP_CODE    - code to execute at end of triangle
+ *
+ * The following macro MUST be defined:
+ *    RENDER_SPAN(span) - code to write a span of pixels.
+ *
+ * This code was designed for the origin to be in the lower-left corner.
+ *
+ * Inspired by triangle rasterizer code written by Allen Akin.  Thanks Allen!
+ *
+ *
+ * Some notes on rasterization accuracy:
+ *
+ * This code uses fixed point arithmetic (the GLfixed type) to iterate
+ * over the triangle edges and interpolate ancillary data (such as Z,
+ * color, secondary color, etc).  The number of fractional bits in
+ * GLfixed and the value of SUB_PIXEL_BITS has a direct bearing on the
+ * accuracy of rasterization.
+ *
+ * If SUB_PIXEL_BITS=4 then we'll snap the vertices to the nearest
+ * 1/16 of a pixel.  If we're walking up a long, nearly vertical edge
+ * (dx=1/16, dy=1024) we'll need 4 + 10 = 14 fractional bits in
+ * GLfixed to walk the edge without error.  If the maximum viewport
+ * height is 4K pixels, then we'll need 4 + 12 = 16 fractional bits.
+ *
+ * Historically, Mesa has used 11 fractional bits in GLfixed, snaps
+ * vertices to 1/16 pixel and allowed a maximum viewport height of 2K
+ * pixels.  11 fractional bits is actually insufficient for accurately
+ * rasterizing some triangles.  More recently, the maximum viewport
+ * height was increased to 4K pixels.  Thus, Mesa should be using 16
+ * fractional bits in GLfixed.  Unfortunately, there may be some issues
+ * with setting FIXED_FRAC_BITS=16, such as multiplication overflow.
+ * This will have to be examined in some detail...
+ *
+ * For now, if you find rasterization errors, particularly with tall,
+ * sliver triangles, try increasing FIXED_FRAC_BITS and/or decreasing
+ * SUB_PIXEL_BITS.

+       * We always sample at pixel centers.  However, we avoid
+       * explicit half-pixel offsets in this code by incorporating
+       * the proper offset in each of x and y during the
+       * transformation to window coordinates.
+       *
+       * We also apply the usual rasterization rules to prevent
+       * cracks and overlaps.  A pixel is considered inside a
+       * subtriangle if it meets all of four conditions: it is on or
+       * to the right of the left edge, strictly to the left of the
+       * right edge, on or below the top edge, and strictly above
+       * the bottom edge.  (Some edges may be degenerate.)
+       *
+       * The following discussion assumes left-to-right scanning
+       * (that is, the major edge is on the left); the right-to-left
+       * case is a straightforward variation.
+       *
+       * We start by finding the half-integral y coordinate that is
+       * at or below the top of the triangle.  This gives us the
+       * first scan line that could possibly contain pixels that are
+       * inside the triangle.
+       *
+       * Next we creep down the major edge until we reach that y,
+       * and compute the corresponding x coordinate on the edge.
+       * Then we find the half-integral x that lies on or just
+       * inside the edge.  This is the first pixel that might lie in
+       * the interior of the triangle.  (We won't know for sure
+       * until we check the other edges.)
+       *
+       * As we rasterize the triangle, we'll step down the major
+       * edge.  For each step in y, we'll move an integer number
+       * of steps in x.  There are two possible x step sizes, which
+       * we'll call the ``inner'' step (guaranteed to land on the
+       * edge or inside it) and the ``outer'' step (guaranteed to
+       * land on the edge or outside it).  The inner and outer steps
+       * differ by one.  During rasterization we maintain an error
+       * term that indicates our distance from the true edge, and
+       * select either the inner step or the outer step, whichever
+       * gets us to the first pixel that falls inside the triangle.
+       *
+       * All parameters (z, red, etc.) as well as the buffer
+       * addresses for color and z have inner and outer step values,
+       * so that we can increment them appropriately.  This method
+       * eliminates the need to adjust parameters by creeping a
+       * sub-pixel amount into the triangle at each scanline.

+ * \struct SWvertex
+ * \brief Data-structure to handle vertices in the software rasterizer.
+ * 
+ * The software rasterizer now uses this format for vertices.  Thus a
+ * 'RasterSetup' stage or other translation is required between the
+ * tnl module and the swrast rasterization functions.  This serves to
+ * isolate the swrast module from the internals of the tnl module, and
+ * improve its usefulness as a fallback mechanism for hardware
+ * drivers.
+ *
+ * Full software drivers:
+ *   - Register the rastersetup and triangle functions from
+ *     utils/software_helper.
+ *   - On statechange, update the rasterization pointers in that module.
+ *
+ * Rasterization hardware drivers:
+ *   - Keep native rastersetup.
+ *   - Implement native twoside,offset and unfilled triangle setup.
+ *   - Implement a translator from native vertices to swrast vertices.
+ *   - On partial fallback (mix of accelerated and unaccelerated
+ *   prims), call a pass-through function which translates native
+ *   vertices to SWvertices and calls the appropriate swrast function.
+ *   - On total fallback (vertex format insufficient for state or all
+ *     primitives unaccelerated), hook in swrast_setup instead.

+/**
+ * \mainpage The TNL-module
+ *
+ * TNL stands for "transform and lighting", i.e. this module implements
+ * a pipeline that receives as input a buffer of vertices and does all
+ * necessary transformations (rotations, clipping, vertex shader etc.)
+ * and passes then the output to the rasterizer.
+ *
+ * The tnl_pipeline contains the array of all stages, which should be
+ * applied. Each stage is a black-box, which is described by an
+ * tnl_pipeline_stage. The function ::_tnl_run_pipeline applies all the
+ * stages to the vertex_buffer TNLcontext::vb, where the vertex data
+ * is stored. The last stage in the pipeline is the rasterizer.
+ *
+ * The initial vertex_buffer data may either come from an ::immediate
+ * structure or client vertex_arrays or display lists:
+ *
+ *
+ * - The ::immediate structure records all the GL commands issued between
+ * glBegin and glEnd.  \n
+ * The structure accumulates data, until it is either full or it is
+ * flushed (usually by a state change). Before starting then the pipeline,
+ * the collected vertex data in ::immediate has to be pushed into
+ * TNLcontext::vb.
+ * This happens in ::_tnl_vb_bind_immediate. The pipeline is then run by
+ * calling tnl_device_driver::RunPipeline = ::_tnl_run_pipeline, which
+ * is stored in TNLcontext::Driver.   \n
+ * An ::immediate does (for performance reasons) usually not finish with a
+ * glEnd, and hence it also does not need to start with a glBegin.
+ * This means that the last vertices of one ::immediate may need to be
+ * saved for the next one.
+ *
+ *
+ * - NOT SURE ABOUT THIS: The vertex_arrays structure is used to handle
+ * glDrawArrays etc.  \n
+ * Here, the data of the vertex_arrays is copied by ::_tnl_vb_bind_arrays
+ * into TNLcontext::vb, so that the pipeline can be started.

+ * drivers did in Mesa 3.4.  These stages are basically black boxes,
+ * and should be left intact.
+ *
+ * To customize the pipeline, consider:
+ *
+ * - removing redundant stages (making sure that the software rasterizer
+ *   can cope with this on fallback paths).  An example is fog
+ *   coordinate generation, which is not required in the FX driver.
+ *
+ * - replacing general-purpose machine-independent stages with
+ *   general-purpose machine-specific stages.  There is no example of
+ *   this to date, though it must be borne in mind that all subsequent
+ *   stages that reference the output of the new stage must cope with
+ *   any machine-specific data introduced.  This may not be easy
+ *   unless there are no such stages (ie the new stage is the last in
+ *   the pipe).
+ *
+ * - inserting optimized (but specialized) stages ahead of the
+ *   general-purpose fallback implementation.  For example, the old
+ *   fastpath mechanism, which only works when the VB->Elts input is
+ *   available, can be duplicated by placing the fastpath stage at the
+ *   head of this pipeline.  Such specialized stages are currently
+ *   constrained to have no outputs (ie. they must either finish the *
+ *   pipeline by returning GL_FALSE from run(), or do nothing).
+ *
+ * Some work can be done to lift some of the restrictions in the final
+ * case, if it becomes necessary to do so.

+/* Display list compiler attempts to store lists of vertices with the
+ * same vertex layout.  Additionally it attempts to minimize the need
+ * for execute-time fixup of these vertex lists, allowing them to be
+ * cached on hardware.
+ *
+ * There are still some circumstances where this can be thwarted, for
+ * example by building a list that consists of one very long primitive
+ * (eg Begin(Triangles), 1000 vertices, End), and calling that list
+ * from inside a different begin/end object (Begin(Lines), CallList,
+ * End).  
+ *
+ * In that case the code will have to replay the list as individual
+ * commands through the Exec dispatch table, or fix up the copied
+ * vertices at execute-time.
+ *
+ * The other case where fixup is required is when a vertex attribute
+ * is introduced in the middle of a primitive.  Eg:
+ *  Begin(Lines)
+ *  TexCoord1f()           Vertex2f()
+ *  TexCoord1f() Color3f() Vertex2f()
+ *  End()
+ *
+ *  If the current value of Color isn't known at compile-time, this
+ *  primitive will require fixup.
+ *
+ *
+ * The list compiler currently doesn't attempt to compile lists
+ * containing EvalCoord or EvalPoint commands.  On encountering one of
+ * these, compilation falls back to opcodes.  
+ *
+ * This could be improved to fallback only when a mix of EvalCoord and
+ * Vertex commands are issued within a single primitive.

+
+NOTE:
+
+These files are incomplete.  They do not yet form a working
+implementation of hte concepts discused below.
+
+
+OVERVIEW
+
+The t_dd_imm_* files form a set of templates to produce driver -
+specific software tnl modules for a small subset of transformation and
+lighting states.
+
+The approach is quite different to the large vertex buffers of the
+src/tnl module, and is based around a cache of four recent vertices
+and a 'current' vertex which is updated directly from the Color,
+Normal, Texcoord, SecondaryColor and Fog entrypoints.
+
+The current vertex is actually a composite of the ctx->Current values
+and a partial hardware vertex maintained where the hardware values
+differ from those in ctx->Current.  For example, clamped color values
+are kept in the hardware vertex, while texcoords remain in
+ctx->Current.
+
+A crude diagram:
+
+       		+--------------+	+-------------------+
+		| ctx->Current |	| Current-HW-vertex |
+		+--------------+	+-------------------+
+		       \       	       	       	  /
+		       	\      			 /
+			 \     			/
+			  \    		       /
+			   ---------   --------
+			       	   |   |      
+			       	   v   v     
+	+--------+   +--------+  +--------+  +--------+ 
+	| vert-0 |   | vert-1 |  | vert-2 |  | vert-3 |		       	 
+	+--------+   +--------+  +--------+  +--------+		       	 
+				     |
+				     |
+				     v
+				     
+				    DMA
+
+
+Here values from ctx->Current and current-HW-vertex are merged to
+build vert-2, which is then dumped to hardware (DMA).  A state machine
+determines which vertex is built in turn, and how the vertices are
+used to present primitives to hardware.  These actions all occur
+during a call to Vertex{234}f{v}.
+
+Each vert-n includes clip coordinates and a clipmask in addition to
+the hardware (window) coordinates.  This information allows clipping
+to take place directly on these vertices, if need be.
+
+t_dd_imm_capi.h
+	
+	Color{34}{fub}{v}() implementations.  These update both
+	ctx->Current (unclamped float colors) and current-HW-vertex
+	with hardware-specific color values (typically unsigned
+	bytes).
+
+	When lighting is enabled, the functions from src/api_noop.c
+	should be used, which just update ctx->Current.  (The
+	current-hw-vertex colors are produced from lighting, which is
+	keyed to Normal3f).
+
+t_dd_imm_vb.c
+
+	Support functions for clipping and fallback.  See
+	t_dd_imm_primtmp.h.
+
+t_dd_imm_napi.c
+t_dd_imm_napi.h
+
+	Versions of Normal3f{v} to perform lighting with one or more
+	infinite lights.  Updates ctx->Current.Normal and the current
+	HW colors.
+
+	When lighting is disabled, use the functions from api_noop.c
+	instead.
+
+
+t_dd_imm_primtmp.h
+
+	State machine to control emission of vertices and primitives
+	to hardware.  Called indirectly from Vertex{234}f{v}.  Capable
+	of supporting hardware strip and fan primitives, and of
+	decomposing to discreet primitives for clipping or fallback,
+	or where the native primitive is unavailable.
+
+t_dd_imm_tapi.h
+
+	Implementations of TexCoord{v} and MultiTexCoord4f{v}ARB to
+	fire a callback when transitioning to projective texture.
+	Most drivers will need to change vertex format at this point,
+	some may need to enable a software rasterization fallback.
+
+t_dd_imm_vapi.h
+
+	Implementations of Vertex{234}f{v}.  These perform
+	transformation and cliptesting on their arguments, then jump
+	into the state machine implemented in primtmp.h.
+
+t_dd_imm_vertex.h
+
+	Support functions for building and clip-interpolating hardware
+	vertices.  Called from primtmp.h.

+ *     ctx->Driver.QuadFunc
+ *     ctx->Driver.TriangleFunc
+ *     ctx->Driver.LineFunc
+ *     ctx->Driver.PointsFunc
+ *
+ * DO_TWOSIDE:   Plug back-color values from the VB into backfacing triangles,
+ *               and restore vertices afterwards.
+ * DO_OFFSET:    Calculate offset for triangles and adjust vertices.  Restore
+ *               vertices after rendering.
+ * DO_FLAT:      For hardware without native flatshading, copy provoking colors
+ *               into the other vertices.  Restore after rendering.
+ * DO_UNFILLED:  Decompose triangles to lines and points where appropriate.
+ * DO_TWOSTENCIL:Gross hack for two-sided stencil.
+ *
+ * HAVE_RGBA: Vertices have rgba values (otherwise index values).
+ * HAVE_SPEC: Vertices have secondary rgba values.
+ *
+ * VERT_X(v): Alias for vertex x value.
+ * VERT_Y(v): Alias for vertex y value.
+ * VERT_Z(v): Alias for vertex z value.
+ * DEPTH_SCALE: Scale for constant offset.
+ * REVERSE_DEPTH: Viewport depth range reversed.
+ *
+ * VERTEX: Hardware vertex type.
+ * GET_VERTEX(n): Retreive vertex with index n.
+ * AREA_IS_CCW(a): Return true if triangle with signed area a is ccw.
+ *
+ * VERT_SET_RGBA: Assign vertex rgba from VB color.
+ * VERT_COPY_RGBA: Copy vertex rgba another vertex.
+ * VERT_SAVE_RGBA: Save vertex rgba to a local variable.
+ * VERT_RESTORE_RGBA: Restore vertex rgba from a local variable.
+ *   --> Similar for IND and SPEC.
+ *
+ * LOCAL_VARS(n): (At least) define local vars for save/restore rgba.

+ * Select the syntax appropriate to the 386 assembler being used
+ * To add support for more assemblers add more columns to the CHOICE
+ * macro.  Note that register names must also have uppercase names
+ * to avoid macro recursion. e.g., #define ah %ah recurses!
+ *
+ * NB 1.  Some of the macros for certain assemblers imply that the code is to
+ *	  run in protected mode!!  Caveat emptor.
+ *
+ * NB 2.  486 specific instructions are not included.  This is to discourage
+ *	  their accidental use in code that is intended to run on 386 and 486
+ *	  systems.
+ *
+ * Supported assemblers:
+ *
+ * (a) AT&T SysVr4 as(1):	define ATT_ASSEMBLER
+ * (b) GNU Assembler gas:	define GNU_ASSEMBLER (default)
+ * (c) Amsterdam Compiler kit:	define ACK_ASSEMBLER
+ * (d) The Netwide Assembler:	define NASM_ASSEMBLER
+ * (e) Microsoft Assembler:	define MASM_ASSEMBLER (UNTESTED!)
+ *
+ * The following naming conventions have been used to identify the various
+ * data types:
+ *		_SR = segment register version
+ *	Integer:
+ *		_Q = quadword	= 64 bits
+ *		_L = long	= 32 bits
+ *		_W = short	= 16 bits
+ *		_B = byte	=  8 bits
+ *	Floating-point:
+ *		_X = m80real	= 80 bits
+ *		_D = double	= 64 bits
+ *		_S = single	= 32 bits
