	crash with some Mac OS X .dfont files.  Submitted by Masatake
	Yamato.

	* autogen.sh: Small fix to get it working on Mac OS X properly:
	The issue is that GNU libtool is called `glibtool' on this platform,
	and we must call `glibtoolize', since `libtoolize' doesn't exist.

2007-01-08  David Turner  <[e-mail]>

	* docs/CHANGES: Updated.

	* include/freetype/ftgasp.h, src/base/ftgasp.c: New files which add

	corresponding to a given character pixel size.

	* src/sfnt/ttload.c (tt_face_load_gasp): Add version check for the
	`gasp' table, in order to avoid potential problems with later
	versions.

	* include/freetype/config/ftheader.h (FT_GASP_H): New macro for

2007-01-06  Werner Lemberg  <[e-mail]>

	* src/cff/cffload.c (cff_index_init): Remove unused variable.
	(cff_index_read_offset): s/perror/errorp/ to avoid global shadowing.

2007-01-04  David Turner  <[e-mail]>

	* src/pfr/pfrobjs.c (pfr_face_init): Detect non-scalable fonts
	correctly.  This fixes Savannah bug #17876.


	Do not allocate interpreter-specific tables in memory if we are not
	going to load glyphs with the bytecode interpreter anyway.

	* src/truetype/ttgload.c (tt_loader_init): Load execution context
	only if glyph is hinted.
	Updated.
	* src/truetype/ttobjs.h (TT_SizeRec): Add members `bytecode_ready'
	and `cvs_ready'.
	Add `tt_size_ready_bytecode' declaration.
	* src/truetype/ttobjs.c (tt_size_done_bytecode,
	tt_size_init_bytecode, tt_size_ready_bytecode): New functions.
	(tt_size_init): Move most code into `tt_size_init_bytecode'.
	(tt_size_done): Move most code into `tt_size_done_bytecode'.
	(tt_size_reset): Move some code to `tt_size_ready_bytecode'.


	Don't extract the metrics table from the SFNT font file.  Instead,
	reparse it on each glyph load.  The runtime difference is not
	noticeable, and it can save a lot of heap memory when memory-mapped
	files are not used.

	* include/freetype/internal/tttypes.h (TT_FaceRec): Add members
	`horz_metrics_offset' and `vert_metrics_ofset'.
	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics):
	Updated.


	* src/sfnt/ttcmap.c (tt_cmap4_validate): Slight optimization.


	Do not load the CFF index offsets into memory, since this wastes a
	*lot* of heap memory with large Asian CFF fonts.  There is no
	significant performance loss.

	* src/cff/cffload.h: Add `cff_charset_cid_to_gindex' declaration.
	* src/cff/cfftypes.h (CFF_IndexRec): Add fields `start' and
	`data_size'.
	(CFF_CharsetRec): Add field `num_glyphs'.

	* src/cff/cffload.c (cff_index_read_offset, cff_index_load_offsets,
	cff_charset_cid_to_gindex): New functions.
	(cff_new_index): Renamed to...
	(cff_index_init): This.  Update all callers.
	Updated -- some code has been moved to `cff_index_load_offsets'.
	(cff_done_index): Renamed to...
	(cff_index_done): This.  Update all callers.
	(cff_index_get_pointers, cff_index_access_element): Updated to use
	stream offsets.
	(cff_charset_compute_cids): Set `num_glyphs' field.
	(cff_encoding_load): Updated.

	* src/cff/cffgload.c (cff_slot_load): Updated.

2007-01-04  David Turner  <[e-mail]>

	* docs/INSTALL.UNIX: Simplify some parts, add reference to
	autogen.sh and pointer to README.CVS.

	* README.CVS: Add common problem description and solution
	when running autogen.sh.

	* docs/INSTALL: Add reference to MacOS X.

	* docs/MAKEPP, docs/INSTALL.MAC: New documentation files.

	* docs/TODO: Remove obsolete items.

	* src/raster/ftraster.c: (TRaster_Instance): Replace it with...
	(TWorker): This.
	Remove `count_table' and `memory'.
	Make `grays' a pointer.
	(TRaster): New structure.
	(count_table): New static array.
	(RAS_ARGS, RAS_ARG, RAS_VARS, RAS_VAR, FT_UNUSED_RASTER, cur_ras,
	Vertical_Gray_Sweep_Step, ft_black_new, ft_black_done,
	ft_black_set_mode, ft_black_render): Updated.
	(ft_black_init): Don't initialize `count_table'.
	(ft_black_reset): Use the render pool.  This saves about 6KB of
	heap space for each FT_Library instance.

	* src/smooth/ftgrays.c (TRaster): Replaced with...
	(TWorker): This.
	Remove `memory'.
	(TRaster): New structure.

	(RAS_ARG_, RAS_ARG, RAS_VAR_, RAS_VAR, ras, gray_render_line,
	gray_move_to, gray_line_to, gray_conic_to, gray_cubic_to,
	gray_render_span, gray_raster_render): Updated.
	(gray_raster_reset): Use the render pool.  This saves about 6KB of
	heap space for each FT_Library instance.

	* src/sfnt/sfobjs.c, src/sfnt/ttkern.c, src/sfnt/ttkern.h,
	src/sfnt/ttmtx.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
	src/truetype/ttpload.c, include/freetype/config/ftoption.h: Remove
	FT_OPTIMIZE_MEMORY macro (and code for !FT_OPTIMIZE_MEMORY) since
	the optimization is no longer experimental.

	* src/pshinter/pshalgo.c (psh_glyph_interpolate_normal_points):
	Remove a typo that results in no hinting and a memory leak with some
	large Asian CFF fonts.

	* src/base/ftobjs.c (FT_Done_Library): Remove a subtle memory leak
	which happens when FT_Done_Library is called with still opened
	CFF_Faces in it.  We need to close all faces before destroying the
	modules, or else some bad things (memory leaks) may happen.

2007-01-02  Werner Lemberg  <[e-mail]>

	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate):
	Remove compiler warning.

	* src/sfnt/sfobjs.c: Add documentation comment.

	* src/gxvalid/gxvkern.c (gxv_kern_subtable_fmt0_pairs_validate): New
	function.
	Check uniqueness of the gid pairs.
	(gxv_kern_subtable_fmt0_validate): Move some code to
	`gxv_kern_subtable_fmt0_pairs_validate'.

2006-12-22  David Turner  <[e-mail]>

	* src/autofit/aflatin.c, src/truetype/ttgload.c: Remove compiler
	warnings.

	* builds/win32/visualc/freetype.vcproj: Add _CRT_SECURE_NO_DEPRECATE
	to avoid deprecation warnings with Visual C++ 8.

2006-12-16  Anders Kaseorg  <[e-mail]>

	* src/base/ftlcdfil.c (FT_Library_SetLcdFilter)
	[FT_FORCE_LIGHT_LCD_FILTER]: Fix typo.

2006-12-15  suzuki toshiya  <[e-mail]>

	* include/freetype/internal/services/svotval.h: Add `volatile' to
	sync with the modification by Jens Claudius on 2006-08-22; cf.
	  http://cvs.savannah.gnu.org/viewcvs/freetype/freetype2/src/otvalid/otvmod.c?r1=1.4&r2=1.5

2006-12-15  suzuki toshiya  <[e-mail]>

	* src/base/ftmac.c: Specialized for Mac OS X only.
	* builds/unix/ftconfig.in: Fixed for ppc64 missing Carbon framework.
	* builds/unix/configure.raw: Ditto. When explicit switches for
	FSSpec/FSRef/QuickDraw/ATS availability are given to configure,
	builds/mac/ftmac.c is used instead of default src/base/ftmac.c.

2006-12-15  suzuki toshiya  <[e-mail]>

	* builds/mac/ftmac.c: Copied src/base/ftmac.c for legacy system.
	* builds/mac/FreeType.m68k_cfm.make.txt: Fix to use builds/mac/ftmac.c
	instead of src/base/ftmac.c
	* builds/mac/FreeType.ppc_carbon.make.txt: Ditto.
	* builds/mac/FreeType.ppc_classic.make.txt: Ditto.
	* builds/mac/FreeType.m68k_far.make.txt: Ditto, and exclude gxvalid.c
	that cannot be built at present.

2006-12-15  suzuki toshiya  <[e-mail]>

	* src/base/ftobjs.c: Improvement of resource fork handler for
	POSIX, cf.
	  http://lists.gnu.org/archive/html/freetype-devel/2006-10/msg00025.html
	(Mac_Read_sfnt_Resource): Count only `sfnt' resource of suitcase font
	format or .dfont, to simulate the face index number counted by ftmac.c.
	(IsMacResource): Return the number of scalable faces correctly.

2006-12-10  Werner Lemberg  <[e-mail]>

	* builds/toplevel.mk (version): Protect against `distclean' target.

2006-12-09  Werner Lemberg  <[e-mail]>

	* builds/*/*def.mk, builds/*/detect.mk (CAT): Define to either `cat'
	or `type'.

	* builds/freetype.mk (version): Extracted from freetype.h, using
	GNU make's built-in string functions.
	(refdoc): Use $(version) instead of static version number.

2006-12-08  Werner Lemberg  <[e-mail]>

	* builds/toplevel.mk (dist): Extract version number from freetype.h.
