+ \title Third-Party Licenses Used in Qt
+ \ingroup licensing
+ \brief License information for third-party libraries supplied with Qt.
+
+ Qt includes a number of third-party libraries that are used to provide
+ certain features. Unlike the code described in the
+ \l{Other Licenses Used in Qt}{code used in Qt} document, these
+ libraries are supplied alongside the Qt modules.
+
+ Third Party Software may impose additional restrictions and it is the
+ user's responsibility to ensure that they have met the licensing
+ requirements of the GPL, LGPL, or Qt Commercial license and the relevant
+ license of the Third Party Software they are using.
+
+ Run \c{configure -help} to see any options that may be available for
+ controlling the use of these libraries.

+ conflicts.
+ \i Removed parts of code not relevant when compiled with
+ _STANDALONE_ defined.
+ \i Changed behavior in ftraster.c to follow X polygon filling
+ rules.
+ \i Implemented support in ftraster.c for winding / odd even
+ polygon fill rules.
+ \i Replaced bitmap generation with span generation in ftraster.c
+ \i Renamed: ftraster.h to qblackraster_p.h
+ \i Renamed: ftraster.c to qblackraster.c

+ "real-world" scenes; line drawings, cartoons and other non-realistic images
+ are not its strong suit. JPEG is lossy, meaning that the output image is not
