	Bug 440603 – Minor ABI change

Overview of changes between 1.16.4 and 1.17.0
==============================================

General:

- Text justification.  A simple justification algorithm is implemented
  that tries to justify by expanding spaces in the line, and if none
  found, by adjust letter spacing.  [Based on patch by Mathias
  Hasselmann]

- The pango_script_get_sample_language() function is modified to use
  the value of environment variables PANGO_LANGUAGE or LANGUAGE
  (checked in that order) to make guess better languages for scripts.
  The env var should be a list of language tags, like "en:fa" for
  example where in effect makes Pango choose Persian (fa) fonts
  instead of Arabic (ar) fonts when a run of text in the Arabic script
  is found in an otherwise non-Arabic layout.

  This trick is also useful for East Asian languages.  For example a
  Japanese user that cannot set her primary language to Japanese can
  still set PANGO_LANGUAGE="ja" and Pango will map CJK characters to
  Japanese.

  The LANGUAGE env var is a standard gettext variable listing
  languages the user wants to receive UI translated messages in.
  However, since most packages don't provide separate English
  translations, setting LANGUAGE="en:ja" doesn't have the intended
  effect and UI messages will be shown in Japanese.  For these
  situations one can use LANGUAGE="en:C:ja".  Pango skips the special
  language tag 'C'.

- Simplified embedded-shape rendering with pangocairo backends do.
  [Richard Hult]

- New header file: Moved PangoLanguage APIs into its own header
  pango-language.h, which is included from pango-types.h.

- ATSUI backend now lists synthesized italic faces like other

- Misc optimizations and fixes.

OpenType Layout Engine Improvements:

- Vertical glyph variants are not selected in vertical text if the
  font supports them.

- Instead of hardcoded OpenType script tag in each module, and using
  Default Language System unconditionally, Pango will now find and use
  the script/lang-sys pair that best matches the detected script and
  language of a run of text.  Moreover, it also applies the OpenType
  'locl' feature.
  
  These, plus the PANGO_LANGUAGE env var, give font designers and
  users lots of options to provide/choose language-specific glyph
  variants.
  
  Only basic, arabic, and syriac modules updated to take advantage of
  the new support so far.

New pango-view command line options:

	--align
	--justify
	--language

Public API Changes:

- New public pangocairo API:

	PangoCairoShapeRendererFunc
	pango_cairo_context_set_shape_renderer() 
	pango_cairo_context_get_shape_renderer() 

  These are used by the default pangocairo renderer to render shape
  attributes (see examples/cairoshape.c).  Cairo-based PangoRenderer
  implementations outside Pango may want to implement the draw_shape()
  method similarly to provide compatibility with these new APIs.  (See
  bug #437533 for GdkPangoRenderer for example.)

- Other public API changes:

	New is_expandable_space member in PangoLogAttr
	New macro PANGO_UNITS_ROUND()

- New OpenType engine API.  These are engine API, for use by Pango
  modules, and typically need not to be bound by language bindings:

	PANGO_OT_NO_FEATURE
	PANGO_OT_NO_SCRIPT
	PANGO_OT_TAG_DEFAULT_SCRIPT
	PANGO_OT_TAG_DEFAULT_LANGUAGE
	PangoOTFeatureMap
	PangoOTRulesetDescription
	pango_ot_ruleset_get_for()
	pango_ot_ruleset_new_for()
	pango_ot_ruleset_maybe_add_feature()
	pango_ot_ruleset_maybe_add_features()
	pango_ot_ruleset_description_hash()
	pango_ot_ruleset_description_equal()
	pango_ot_ruleset_description_copy()
	pango_ot_ruleset_description_free()
	pango_ot_tag_from_script()
	pango_ot_tag_to_script()
	pango_ot_tag_from_language()
	pango_ot_tag_to_language()

- Bugs fixed in this release:

	Bug 64538 – pango_layout_set_justify() doesn't work
	Bug 325714 – Pango should respect $LANGUAGE
	Bug 414264 – Pango vertical writing support is different with real
		     CJK usage.
	Bug 416515 – Time is not aligned with date on vertical panel
	Bug 429397 – Updated MS Mincho/Gothic are not listed in font dialog
		     properly on Vista/
	Bug 433805 – [Atsui] Approximate char/digit width width often 0
		     (worked around)
	Bug 434160 - [atsui] Italic versions of some faces can't be created
	Bug 435709 – pango_cairo_context_[sg]et_shape_renderer()
	Bug 355789 – Pango misaligns word-wrapped text due to trailing
		     whitespace
	Bug 436154 – Error building the pango.modules file while cross
		     compiling
	Bug 436988 – Adding PangoScript to PangoAnalysis
	Bug 437534 – pango_language_includes_script is buggy

Overview of changes between 1.16.3 and 1.16.4
==============================================

  sure releases are made using it.  Distributions are encouraged to
  build with --enable-gtk-doc such that their Pango docs correctly
  cross reference glib and cairo docs.

	Bug 419262 - Don't create coverage every time it's asked for

Overview of changes between 1.16.0 and 1.16.1
==============================================
- Improved Win32 backend: The Win32 backend has been
  updated to always require Uniscribe at compile-time (it still
  is optional at run-time), and to use the wide-character variants
  of Windows APIs which improves the backend in many ways.  The
  1.16.0 release is obsolete as far as the Win32 backend is
  concerned, and official DLLs were not built for it.
- Misc build system fixes
- Bugs fixed in this release:
	Bug 110521 – can't find bold and/or italic fonts on win32
	Bug 120195 – there are some functions in pangowin32-fontmap.c that
		might maybe should be static
	Bug 407315 – Use wide character Win32 API in the pangowin32 code
	Bug 412654 – SED variable undefined in the `libtool --config' output
		used by configure
	Bug 414297 – Fails to build with --enable-static
		--with-included-modules in thai lang module
		Patch from Loïc Minier

Overview of changes between 1.15.6 and 1.16.0
==============================================
- Improved docs, with an object hierarchy and cross references to glib and
  cairo docs now (may require rebuilding the docs to correctly detect glib
  and cairo prefixes).
- Improved font selection for space characters

Overview of changes between 1.15.5 and 1.15.6
==============================================
- Fix possible crasher in win32 font selection [Owen Taylor]
- Misc build fixes.
- Bugs fixed in this release:
	Bug 399738 – pango 1.15.5 won't compile on Mac OS X: 'FC_HINT_STYLE'
		undeclared (first use in this function)
	Bug 404295 – Crash initializing pango-win32 fontmap

Overview of changes between 1.15.4 and 1.15.5
==============================================
- Fix the "menu accels are two chars wide" bug that was introduced in 1.15.4
- Respect FC_HINT_STYLE in the ft2 backend.  Patch has been in Fedora for ages.
- Require automake 1.9
Bugs fixed in this release:
	Bug 398238 – pangorc file missing from tests directory

Overview of changes between 1.15.3 and 1.15.4
==============================================
General:
- Finish vertical text support.
- Fix various bugs that could cause ellipsization to stop prematurely.
- Fix rendering of background color being off in presence of rise attribute.
- Improved text-on-path example (examples/cairotwisted.c)

Win32 Improvements:
- Don't check for X and don't warn about missing fontconfig. [Tor Lillqvist]
- Automatically use -mms-bitfields on Windows when building with gcc. [Tor]
- Update makefile.msv. [Hans Breuer]

Code base cleanups:
- Whitespace cleanups.  Hopefully patches still apply using patch -l
- Replace C++-style // comments with C-style /* */ ones.
- Move the pango-view tool from examples/ into pango-view/.  The examples/
  dir is still available and for simple examples only.

Public API changes:

- New PangoLayout query functions:

	pango_layout_is_wrapped()
	pango_layout_is_ellipsized()
	pango_layout_get_unknown_glyphs_count()

  The is_wrapped and is_ellipsized functions return whether the layout
  had to wrap/ellipsize any paragraphs, as opposed to the get_wrap and
  get_ellipsize that return the wrap/ellipsize mode set.

- Misc new function:
	pango_parse_enum()

  This is more a convenience function for internal use, but set public
  to go with other pango_parse_* functions.  Bindings should feel free
  to ignore this.


- New header files:

  Moved gravity and matrix stuff into their own header files pango-gravity.h
  and pango-matrix.h.  Both are included from pango-types.h.

- Vertical text:

  New attribute types:

	PANGO_ATTR_GRAVITY
	PANGO_ATTR_GRAVITY_HINT.

  New enum type:

	PangoGravityHint

  New macro:

	PANGO_GRAVITY_IS_VERTICAL()

  New public functions:

	pango_attr_gravity_new()
	pango_attr_gravity_hint_new()
	pango_gravity_hint_get_type
	pango_context_set_gravity_hint()
	pango_context_get_gravity_hint()
	pango_gravity_get_for_matrix()
	pango_gravity_get_for_script()

  Removed:
	pango_matrix_to_gravity()

  replaced by pango_gravity_get_for_matrix()
  
  Gravity API added in previous releases:

	PangoGravity
        pango_gravity_get_type
        pango_context_get_base_gravity
        pango_context_get_gravity
        pango_context_set_base_gravity
	pango_font_description_get_gravity
	pango_font_description_set_gravity
	pango_gravity_to_rotation

  A tip on using the vertical text support: If you just want to get correct
  behavior in rotated labels (say, vertical Chinese/Japanese, but rotated
  Latin, etc), all you need to do is to set the context gravity to
  PANGO_GRAVITY_AUTO.  You can do this for example

	#if defined(PANGO_VERSION_CHECK) && PANGO_VERSION_CHECK(1,15,4)
	  pango_context_set_gravity (context, PANGO_GRAVITY_AUTO);
	#endif

Bugs fixed in this release:
	Bug 395328 – Map kATSDeletedGlyphcode to PANGO_GLYPH_EMPTY
	Bug 397337 – Use is_ellipsized and is_wrapped to optimize property
		     changes
	Bug 328585 – Need to know if a layout has unknown glyphs
		     Patch from LingNing Zhang
	Bug 326693 – PangoLayouts should be query-able about their
		     effective properties (width / wrapped / ellipsized / etc)
	Bug 397327 – pango-layout.c: 'pango_layout_is_ellipsized' must return
		     a value
	Bug 323173 – Add layout of mixed direction text for vertical layout
	Bug 394453 – Use -mms-bitfields
	Bug 392628 – Don't check for X on win32


Overview of changes between 1.15.2 and 1.15.3
==============================================
- Fix Hangul crasher and other Hangul bugs introduced in 1.15.2
- Spell-checked docs
- Build fixes
- Don't introduce bitfields in public structs.  This changes some public API
  that was broken in the 1.15 series.  The new struct is backward compatible
  with the older Pango series, but not with earlier 1.15.x devel releases.

- New Public API:

  * PangoAnalysis.flags and PANGO_ANALYSIS_FLAGS_CENTERED_BASELINE.  These are
    mostly only useful for the vertical text support in Pango, but language
    bindings probably want to update their bindings for PangoAnalysis to
    include these.

  * New PangoMatrix methods:

	pango_matrix_transform_distance()
	pango_matrix_transform_point()
	pango_matrix_transform_rectangle()
	pango_matrix_transform_pixel_rectangle()

    The transform_rectangle methods are particularly useful when an
    app/toolkit wants to know the extents of a rotated layout in device
    coordinates.  It will be used by Gtk+ for example, and is used by the
    pango-view tool too.  The _pixel_ variant takes a PangoRectangle in device
    units instead of Pango units.

  * Unit conversion helpers:

	pango_units_from_double()
	pango_units_to_double()
	pango_extents_to_pixels()

    The first two just convert between Pango units (fixed precision) and
    double floating-point numbers.  The current implementations are as simple
    as "(int)floor (d * PANGO_SCALE + 0.5)" and "(double)i / PANGO_SCALE", but
    the idea is to have optimized versions of these that do not use the FPU in
    the future.  That will be appreciated by embedded devices without FPU
    units.  Since the functionality can be generally useful, the API is made
    public.

    The pango_extents_to_pixels() function in conjunction with
    pango_matrix_transform_rectangle() makes it possible to convert extents to
    device space and round then, instead of having to transform rounded
    user-space extents.

- Bugs fixed in this release:
	Bug 351496 – PangoAnalysis::gravity breaks binary compatibility
	Bug 388702 – Crash when there's no Hangul glyph in the font.
	Bug 384543 – FcFontMatch misuse
	Bug 392789 – vpath build fails in basic module
		     Patch from J. Ali Harlow
	Bug 390877 – Don't feed pango-features.h to glib-mkenums
		     Patch from Yevgen Muntyan


Overview of changes between 1.15.1 and 1.15.2
==============================================
* Engines:
  - Improved Hangul shaper engine
  - Improved Indic shaper and language engines
  - Require libthai >= 0.1.7 for the Thai language engine

* Optimizations:
  - Avoid some floating-point operations.  Should cut the number of float
    ops per expose event in pangocairo to a half.
  - Cache ink and logical extents for PangoLayout

* New Public API:

  - New, generated, public header file pango-features.h.  Included by
    pango.h.  Currently contains the version information.  In the future,
    can be expanded to define which backends have been enabled, etc.

  - Public macros and functions for compile- and run-time version checking:

	PANGO_VERSION_ENCODE()
	PANGO_VERSION_MAJOR
	PANGO_VERSION_MINOR
	PANGO_VERSION_MICRO
	PANGO_VERSION
	PANGO_VERSION_STRING
	PANGO_VERSION_CHECK()
	pango_version()
	pango_version_string()
	pango_version_check()

    The scheme chosen here is a mixture of approaches taken by glib and cairo.
    The advantage over the glib model is that there are no public variables,
    but it still gives access to a string and numerical representation of the
    version number at compile- and run-time.
    
    The macros enable conditional compilation of code depending on newer Pango
    APIs, while the runtime functions allow refusing to run against old
    versions of the library.

  - New, readonly, version of methods that give read/write access to the
    internals of PangoLayout:

	pango_layout_get_line_readonly()
	pango_layout_get_lines_readonly()
	pango_layout_iter_get_line_readonly()
	pango_layout_iter_get_run_readonly()

    These should be used when you do not intend to modify the run/line,
    which is most of the time the case.  The only exception known to me
    is Firefox that adjusts glyph widths to do justification.  Most other
    uses that do not write to the returned structs (or structs accessible from
    them) should be ported to the new readonly API to benefit from major
    optimizations (in this case, line extents caching).  The list includes,
    but is not limited to, Gtk+, SWT, ClassPath, gnome-applets, libgnomeprint,
    xmlroff, GtkMathView, Conglomerate, Dia, Anjuta, wxWindows, The Gimp, 
    and various other applications/libraries:

      http://www.google.com/codesearch?hl=en&q=+pango_layout_(iter_)%3Fget_(lines%3F%7Crun)%5B%5E_%5D&start=50&sa=N

    Worth noting here is that, many uses of pango_layout_get_lines() can be
    replaced by a pango_layout_get_iter() that works both more elegantly and
    more efficiently.  The versioning macros introduced in this release can be
    used to make code use these new symbols without breaking compilation
    against older Pango (though, such code compiled with the new Pango cannot
    be run against an older Pango).

  - pango_language_get_default(): Note that, this does not make Pango
    fallback to the default language automatically (yet), but the user can
    use this function to set the default language of the locale on a context:

	  pango_context_set_language (context, pango_language_get_default());

    This essentially deprecates gtk_get_default_language().  The pango-view
    tool has been updated to use this feature, so it now respects $LANG when
    choosing fonts.

  - pango_color_to_string().

* Bugs fixed in this release:
	Bug 326099 – Setting width, indentation and ellipsizing doesn't work
		     as I would expect
	Bug 385478 – Fix tests on OPD platform
	Bug 319808 – Patch to let pango support artifical italic, bold and
		     bold italic styles for the fonts which don't have these styles.
		     Patch from James Su
	Bug 385321 – Worst case expansion for Sinhala
		     Patch from Harshula
	Red Hat Bug 211574: [hi/ml/si_LK] cursor naviation is wrong when
		     using ZWJ (200d)
		     Patch from LingNing Zhang
	Red Hat Bug 216424: [te_IN] pango - consonant + dependent vowel (ai)

		     Patch from Matthew Barnes
	Red Hat Bug 216850: Issue in combination with vowels (ml_IN)
		     Patch from LingNing Zhang
	Bug 382437 – tests/testboundaries fails
	Bug 333982 – Fallback to $LANG whenever NULL PangoLanguage is used
		     Patch from LingNing Zhang

Overview of changes between 1.15.0 and 1.15.1
==============================================
* Add Thai langauage engine. (currently makes tests/testboundary fail.)
* Add Lao and improved Thai sample text.
* Improved Indic module.
* Output correct path for hexboxes in pango_cairo_layout_path().
* Implement get_resolution method for the FT2 fontmap.  Shouldn't make
  any difference whatsoever.  Open a bug if it does.
* Misc small fixes.

* Optimizations:
  - Rework PangoLayout algorithms to avoid calling a recursive call to
    pango_layout_get_extents().  Avoids one pango_font_get_glyph_extents()
    call per glyph per layout rendering.  We now make 2 such calls.
  - Don't cache run_logical_rect in PangoLayoutIter.
    Avoids one pango_font_get_glyph_extents() call per glyph per layout
    rendering.  We are down to 1 now.
  - Cache line extents.  This avoids the final pango_font_get_glyph_extents()
    call per glyph per layout rendering.  Now we don't make any
    pango_font_get_glyph_extents() calls when rendering a layout (some
    conditions apply)!
  - Replace PANGO_IS_RENDERER with PANGO_IS_RENDERER_FAST for most
