changelog

qt专门用于嵌入式的图形开发GUI

	      with the uninstallation of FaceIDs

	    - the image and sbit cache are now abstract classes, that
	      can be extended much more easily by client applications

	    - better performance in certain areas. Further optimizations
	      to come shortly anyway...

	    - the FTC_CMapCache_Lookup function has changed its signature,
	      charmaps can now only be retrieved by index

	    - FTC_Manager_Lookup_Face => FTC_Manager_LookupFace
	      FTC_Manager_Lookup_Size => FTC_Manager_LookupSize (still in
	      private header for the moment)

	* Version 2.1.7 released.
	=========================


	* include/freetype/freetype.h (FREETYPE_PATCH): Set to 7.

	* builds/unix/ft2unix.h: Fix comments.

	* builds/unix/ftconfig.in: Synchronized with ANSI version.
	Use `#undef' in templates as recommended in the autoconf
	documentation.
	Since real `#undef' lines don't survive during configuration, use
	`/undef' instead; the postprocessing facility of the
	AC_CONFIG_HEADERS autoconf macro converts them to `#undef'.

	* builds/unix/install.mk (install): Install Unix version of
	`ftconfig.h'.

	* builds/unix/unix-cc.in (CFLAGS): Set FT_CONFIG_CONFIG_H macro
	to include the correct `ftconfig.h' file.

	* builds/unix/ft-munmap.m4 (FT_MUNMAP_DECL): Removed.
	(FT_MUNMAP_PARAM): Updated syntax to autoconf 2.59.

	* builds/unix/freetype2.m4: Updated syntax to autoconf 2.59.

	* builds/unix/configure.ac: Use AC_CONFIG_HEADERS instead of
	AC_CONFIG_HEADER to create ftconfig.h, and use second argument
	to replace `/undef' with `#undef'.
	Don't use FT_MUNMAP_DECL but AC_CHECK_DECLS to check for munmap.
	Use AS_HELP_STRING in AC_ARG_WITH.
	Update syntax to autoconf 2.59.

	* builds/unix/ltmain.sh: Regenerated with `libtoolize --force
	--copy' from libtool 1.5.
	* builds/unix/aclocal.m4: Regenerated with `aclocal -I .' from
	automake 1.7.8.
	* builds/unix/configure: Regenerated with autoconf 2.59.
	* builds/unix/config.guess, builds/unix/config.sub: Updated from
	`config' CVS module at subversions.gnu.org
	* builds/unix/install-sh, builds/unix/mkinstalldirs: Updated from
	`texinfo' CVS module at subversions.gnu.org.

	* builds/vms/ftconfig.h: Synchronized with ANSI version.
