2006-06-25  Jens Claudius  <jens.claudius@yahoo.com>

	The Type 1 parser now skips over top-level procedures as required
	for a `Simplified Parser'.  This makes the parser more robust as it

	StyleMapping table.
	(count_faces): Call `HUnlock' after all FOND utilization.

2006-06-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Public API of TrueTypeGX, OpenType, and classic kern table validator
	should return `FT_Err_Unimplemented_Feature' if validation service
	is unavailable (disabled in `modules.cfg').  It is originally
	suggested by David Turner, cf.
	http://lists.gnu.org/archive/html/freetype-devel/2005-11/msg00078.html

2006-06-06  David Turner  <david@freetype.org>

	Fix memory leak described in Savannah bug #16759.

	We change `ps_unicodes_init' so that it also takes a
	`free_glyph_name' callback to release the glyph names returned by
	`get_glyph_name'

	theorically happen.  This fixes Savannah bug #16669.

	* src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
	of `face->num_glyphs' which missed the last glyph, due to
	the offset-by-1 computation, since the PFR format doesn't
	guarantee that glyph index 0 corresponds to the `missing
	glyph.  This fixes Savannah bug #16668.

2006-05-25  Werner Lemberg  <wl@gnu.org>

	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't comment out
	`-no-undefined'.  Reported by Christian Biesinger.

	* src/truetype/ttgload.c (TT_Load_Composite_Glyph)
	[FT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Make it compilable again.

2006-05-17  David Turner  <david@freetype.org>

	This is a major patch used to drastically improve the performance of
	loading glyphs.  This both speeds up loading the glyph vectors
	themselves and the auto-fitter module.

	We now use inline assembler code with GCC to implement `FT_MulFix',
	which is probably the most important function related to the
	engine's performance.

	The resulting speed-up is about 25%.


	* include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
	`cursor' and `limit'.

	(af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
	(af_glyph_hints_reload: Rewrite recognition of weak points.

	* src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
	constant values out of the loops.

	* src/autofit/aftypes.h: Updated.

	* src/base/ftcalc.c (FT_MulFix): Use inline assembler code.

	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
	product to get orientation.

	* src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
	(FT_Stream_OpenGzip): Use it to handle small files directly in
	memory.

	* src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
	Improve performance.

	* src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
	`limit'.

	(TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
	TT_Load_Composite_Glyph): Updated.  Add threshold to protect against
	exceedingly large values of number of contours.  Speed up by
	reducing the number of loops.

	* src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.


	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
	used to detect rogue clients from 4 to 16.  This is to prevent some
	segmentation faults with fonts like `KozMinProVI-Regular.otf' which
	comes from the Japanese Adobe Reader Asian Font pack.

2007-05-17  Werner Lemberg  <wl@gnu.org>

	* src/cff/cffload.c (cff_font_done): Deallocate subfont array.  This
	fixes the first part of Savannah bug #16590.

	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:
	Remove `extern'.

2006-05-02  David Turner  <david@freetype.org>

	Update the memory management functions and macros to safely deal
	with array size buffer overflows.  This corresponds to attemps to
	allocate arrays that are too large.  For an example, consider the
	following code:

	  count = read_uint32_from_file(); array = malloc( sizeof ( Item ) *
	  count ); for ( nn = 0; nn < count; nn++ )
	    array[nn] = read_item_from_file();

	If `count' is larger than `FT_UINT_MAX/sizeof(Item)', the
	multiplication overflows, and the array allocated os smaller than
	the data read from the file.  In this case, the heap will be
	trashed, and this can be used as a denial-of-service attack, or make
	the engine crash later.

	The FT_ARRAY_NEW and FT_ARRAY_RENEW macros now ensure that the new
	count is no larger than `FT_INT_MAX/item_size', otherwise a new
	error code `FT_Err_Array_Too_Large' will be returned.

	Note that the memory debugger now works again when FT_DEBUG_MEMORY
	is defined.  FT_STRICT_ALIASING has disappeared; the corresponding
	code is now the default.


	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [!__cplusplus]:
	Don't use `extern'.

	* include/freetype/fterrdef.h (FT_Err_Array_Too_Large): New error
	code.

	* include/freetype/internal/ftmemory.h (FT_DEBUG_INNER)
	[FT_DEBUG_MEMORY]: New macro.
	(ft_mem_realloc, ft_mem_qrealloc): Pass new object size count also.

	FT_MEM_QRENEW_ARRAY): Redefine.
	(FT_ALLOC_MULT, FT_REALLOC_MULT, FT_MEM_QALLOC_MULT,
	FT_MEM_QREALLOC_MULT): New macros.  Update callers where
	appropriate.
	(FT_MEM_SET_ERROR): Slightly redefine.


	* src/base/ftdbgmem.c (_ft_debug_file, _ft_debug_lineno)
	[FT_DEBUG_MEMORY]: New global variables, replacing...
	(FT_MemTable_Rec) [FT_DEBUG_MEMORY]: Remove `filename' and
	`line_no'.  Update all callers.
	(ft_mem_debug_alloc) [FT_DEBUG_MEMORY]: Avoid possible integer
	overflow.
	(ft_mem_alloc_debug, ft_mem_realloc_debug, ft_mem_qalloc_debug,
	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

	(ft_mem_alloc. ft_mem_realloc, ft_mem_qrealloc): Rewrite.


	* include/freetype/ftstream.h (FT_FRAME_ENTER, FT_FRAME_EXIT,
	FT_FRAME_EXTRACT, FT_FRAME_RELEASE): Use FT_DEBUG_INNER to report the
	place where the frames were entered, extracted, exited or released
	in the memory debugger.

	* src/base/ftstream.c (FT_Stream_ReleaseFrame) [FT_DEBUG_MEMORY]:
	Call ft_mem_free.
	(FT_Stream_EnterFrame) [FT_DEBUG_MEMORY]: Use ft_mem_qalloc.
	(FT_Stream_ExitFrame) [FT_DEBUG_MEMORY]: Use ft_mem_free.

	* src/cache/ftccmap.c (FTC_OldCMapType, FTC_OldCMapIdRec,
	FTC_OldCMapDesc) [FT_CONFIG_OPTION_OLD_INTERNALS]: New data
	structures and enumerations.
	(FTC_CMapCache_Lookup) [FT_CONFIG_OPTION_OLD_INTERNALS]: New
	compatibility code.

2006-02-23  Chia-I Wu  <b90201047@ntu.edu.tw>

	* include/freetype/ftoutln.h (enum FT_Orientation): New value
	`FT_ORIENTATION_NONE'.

	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,
	ft_contour_enclosed, ft_outline_get_orientation): Another version of
	`FT_Outline_Get_Orientation'.  This version differs from the public
	one in that each part (contour not enclosed in another contour) of the
	outline is checked for orientation.
	(FT_Outline_Embolden): Use `ft_outline_get_orientation'.

	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Render the outline and
	use bitmap's embolden routine when the outline one failed.

2006-02-22  Chia-I Wu  <b90201047@ntu.edu.tw>

	* modules.cfg: Compile in ftotval.c and ftxf86.c by default for ABI
	compatibility.

	* src/sfnt/sfobjs.c (sfnt_done_face): Fix a memory leak.

	* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_bit_aligned,
	tt_sbit_decoder_load_byte_aligned) [FT_OPTIMIZE_MEMORY]: Fix sbit
	loading.  (Only tested with bit aligned sbit with x_pos == 0.)

	* src/truetype/ttpload.c (tt_face_load_hdmx,
	tt_face_get_device_metrics) [FT_OPTIMIZE_MEMORY]: `hdmx' is not
	actually used.

2006-02-21  David Turner  <david@freetype.org>

	Add a new API named FT_Get_TrueType_Engine_Type to determine whether
	we have a patented, unpatented, or unimplemented TrueType bytecode
	interpreter.

	The FT_Get_Module_Flags API was removed consequently.

	* include/freetype/ftmodapi.h (FT_Module_Get_Flags): Removed.
	Replaced with...
	(FT_Get_TrueType_Engine_Type): This.
	(FT_TrueTypeEngineType): New enumeration.

	* include/freetype/internal/ftserv.h (FT_SERVICE_TRUETYPE_ENGINE_H):
	New macro.

	* src/base/ftobjs.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
	(FT_Module_Get_Flags): Removed.  Replaced with...
	(FT_Get_TrueType_Engine_Type): This.

	* src/truetype/ttdriver.c: Include FT_SERVICE_TRUETYPE_ENGINE_H.
	(tt_service_truetype_engine): New service structure.
	(tt_services): Register it.

	* include/freetype/internal/services/svtteng.h: New file.


	* src/sfnt/sfobjs.c (sfnt_load_face): Fix silly bug that prevented
	embedded bitmaps from being correctly listed and used.


	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Disable memory optimization
	if FT_CONFIG_OPTION_OLD_INTERNALS is used.  The is necessary because
	libXfont is directly accessing the HMTX data, unfortunately.
	Fix some compiler warnings.
	(tt_face_get_metrics): Ditto.


	* src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix handling of
	character advances.

2006-02-20  David Turner  <david@freetype.org>

	Support binary compatibility with the X.Org server's Xfont library.
	Note that this change unfortunately prevents memory optimizations
	for the embedded bitmap loader.

	* include/freetype/internal/sfnt.h (SFNT_Interface): Move
	`set_sbit_strike' and `load_sbit_metrics' fields to the location of
	version 2.1.8.

	* src/sfnt/sfdriver.c (tt_face_set_sbit_strike_stub): Call
	FT_Size_Request.
	(sfnt_interface): Updated.

	* src/sfnt/ttsbit.c [FT_CONFIG_OPTION_OLD_INTERNALS]: Don't load
	ttsbit0.c.
	(tt_load_sbit_metrics): Make `sbit_small_metrics_fields' static.

	* src/sfnt/ttsbit.h: Updated.

2006-02-17  David Turner  <david@freetype.org>

	* builds/unix/unix-cc.in (LINK_LIBRARY): Don't filter out exported
	functions anymore.  This ensures that all FT_BASE internal functions
	are available for dynamic linking.

	* include/freetype/ftcache.h (FTC_IMAGE_TYPE_COMPARE,
	FTC_IMAGE_TYPE_HASH), src/cache/ftcbasic.c (FTC_OldFontRec,
	FTC_OldImageDescRec, FTC_ImageCache_Lookup, FTC_Image_Cache_New,
	FTC_OldImage_Desc, FTC_OLD_IMAGE_FORMAT, ftc_old_image_xxx,
	ftc_image_type_from_old_desc, FTC_Image_Cache_Lookup,
	FTC_SBitCache_Lookup, FTC_SBit_Cache_New, FTC_SBit_Cache_Lookup)
	[FT_CONFIG_OPTION_OLD_INTERNALS]: Try to revive old functions of the
	cache sub-system.  We try to recognize old legacy signatures with a
	gross hack (hope it works).

2006-02-17  Werner Lemberg  <wl@gnu.org>

	* devel/ftoption.h: Synchronize with
	include/freetype/config/ftoption.h.

2006-02-16  David Turner  <david@freetype.org>

	Massive changes to the internals to respect the internal object
	layouts and exported functions of FreeType 2.1.7.  Note that the
	cache sub-system cannot be fully retrofitted, unfortunately.

	* include/freetype/config/ftoption.h
	(FT_CONFIG_OPTION_OLD_INTERNALS): New macro.

	* include/freetype/ftcache.h, include/freetype/cache/ftccache.h,
	include/freetype/cache/ftccmap.h,
	include/freetype/internal/ftcalc.h,
	include/freetype/internal/ftdriver.h,
	include/freetype/internal/ftmemory.h,
	include/freetype/internal/ftobjs.h,
	include/freetype/internal/psaux.h, include/freetype/internal/sfnt.h,

	src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/psaux/psauxmod.c,
	src/sfnt/sfdriver.c, src/truetype/ttdriver.c, src/type1/t1driver.c,
	src/type1/t1objs.c, src/type42/t42drivr.c, src/winfonts/winfnt.c:
	Use FT_CONFIG_OPTION_OLD_INTERNALS to revive old functions and data
	structures.

	Move newly added structure elements to the end of the affected
	structure and add stub fields (if FT_CONFIG_OPTION_OLD_INTERNALS is
	defined) to assure binary compatibility with older FreeType
	versions.
	Use FT_CONFIG_OPTION_OLD_INTERNALS to add function stubs for old
	functions:

	  ft_stub_set_char_sizes
	  ft_stub_set_pixel_sizes

	Rename the following internal functions to provide the old function
	names as stubs:

	  FT_Alloc          -> ft_mem_alloc
	  FT_QAlloc         -> ft_mem_qalloc
	  FT_Realloc        -> ft_mem_realloc
	  FT_QRealloc       -> ft_mem_qrealloc
	  FT_Free           -> ft_mem_free
	  FT_Alloc_Debug    -> ft_mem_alloc_debug
	  FT_QAlloc_Debug   -> ft_mem_qalloc_debug
	  FT_Realloc_Debug  -> ft_mem_realloc_debug
	  FT_QRealloc_Debug -> ft_mem_qrealloc_debug
	  FT_Free_Debug     -> ft_mem_free_debug

2006-02-15  Chia-I Wu  <b90201047@ntu.edu.tw>

	* include/freetype/internal/ftobjs.h (FT_Face_InternalRec): Remove
	unused `max_points' and `max_contours'.

	* src/cid/cidobjs.c (cid_face_init), src/type1/t1objs.c
	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Update.

	* include/freetype/internal/tttypes.h (TT_FaceRec): Remove unused
	`max_components'.

	* src/truetype/ttinterp.h (TT_ExecContextRec): Remove unused
	`loadSize' and `loadStack'.

	* src/truetype/ttinterp.c (TT_Done_Context, TT_Load_Context),
	src/sfnt/ttload.c (tt_face_load_maxp): Update.

	* src/cff/cffobjs.h (cff_size_select), src/sfnt/sfdriver.c
	(sfnt_interface), src/truetype/ttdriver.c (tt_size_request): Fix
	compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
	defined.

	* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
	possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
	(finally!)


	For most OpenType tables, `tt_face_load_xxxx' simply loads the table
	and `face->root' is set later in `sfnt_load_face'.  Here, we try to
	make this work for _all_ tables.  Also improve tracing messages.

	* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
	src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
	then exit.  Error handling or setting face->root is done later in
	`sfnt_load_face'.

	* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
	Mac bitmap-only fonts are not scalable.
	Check that `face->header.Units_Per_EM' is not zero.
	(LOAD_, LOADM_): Emit pretty trace messages.

	* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics
	from `eblc'.

	* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
	(load_format_20, load_format_25, tt_face_get_ps_name): Use
	face->max_profile.numGlyphs, instead of face->root.num_glyphs.

2006-02-14  Werner Lemberg  <wl@gnu.org>

	* include/freetype/ftoutln.h (FT_Outline_Embolden): Mention in
	documentation that negative strength values are possible.
	Give an example call.

	* include/freetype/freetype.h (FT_GlyphSlotRec): Improve
	documentation of `outline' field.

	* src/sfnt/sfobjc.s: Inckude FT_INTERNAL_DEBUG_H.
	* src/sfnt/sfdriver.c: Include ttmtx.h.

	* src/autofit/afcjk.c: Include aftypes.h and aflatin.h.

2006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/sfnt/ttmtx.c (tt_face_get_metrics): Typo.

2006-02-14  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/sfnt/ttmtx.c (tt_face_load_hhea, tt_face_load_hmtx): Simply
	return error if table is missing.
	Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.

	* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
	tables.  The last change makes Mac bitmap-only font not load and
	this fixes it.

	* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation
	error when FT_CONFIG_OPTION_INCREMENTAL is defined.

2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>

	Clean up the SFNT_Interface.  In this final pass, `load_hmtx' is
	split from `load_hhea'.

	* include/freetype/internal/sfnt.h, src/sfnt/sfdriver.c,
	src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Split `hmtx' from `hhea'.

	* src/sfnt/sfobjs.c (sfnt_load_face): Update.

2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/sfnt/ttmtx.h, src/sfnt/ttmtx.c: Why are there two copies of
	code...

2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>

	Clean up the SFNT_Interface.  In this pass, we want to treat the
	font directory (offset table and table directory) as a normal table
	like the others.  This also means that TTCs are no longer recognized
	there but in `init_face'.

	* include/freetype/internal/sfnt.h (SFNT_Interface),
	src/sfnt/sfdriver.c: `load_sfnt_header' and `load_directory' are
	combined and renamed to `load_font_dir'.

	* src/sfnt/ttload.h, src/sfnt/ttload.c:
	s/sfnt_dir_check/check_table_dir/.
	`sfnt_init' is moved to sfobjs.c and renamed to `sfnt_open_font'.
	`tt_face_load_sfnt_header' and `tt_face_load_directory' are combined
	and renamed to `tt_face_load_font_dir'.

	* src/sfnt/sfobjs.c (sfnt_init_face): Recognize TTC here.

2006-02-13  Chia-I Wu  <b90201047@ntu.edu.tw>

	Clean up the SFNT_Interface.  Table loading functions are now named
	after the tables' tags; `hdmx' is TrueType-specific and thus the
	code is moved to the truetype module; `get_metrics' is moved here
	from the truetype module so that the code can be shared with the cff
	module.

	This pass involves no real changes.  That is, the code is moved
	verbatim mostly.  The only exception is the return value of
	`tt_face_get_metrics'.

	* include/freetype/internal/sfnt.h, src/sfnt/rules.mk,
	src/sfnt/sfdriver.c, src/sfnt/sfnt.c, src/sfnt/sfobjs.c,
	src/sfnt/ttload.c, src/sfnt/ttload.h, src/sfnt/ttsbit.c,
	src/sfnt/ttsbit.h, src/sfnt/ttsbit0.c: Clean up the SFNT_Interface.

	* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: New files.  Metrics-related
	tables' loading and parsing code is moved to here.
	Move `tt_face_get_metrics' here from the truetype module.  The
	return value is changed from `void' to `FT_Error'.

	* include/freetype/internal/fttrace.h: New trace: ttmtx.

	* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
	parsing code is moved here.
	New function `tt_face_load_prep' split from `tt_face_load_fpgm'.
	`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.

	* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

	* src/truetype/ttgload.c, src/truetype/ttobjs.c: Update.

2006-02-11  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/autofit/afcjk.c (af_cjk_metrics_init): Fix a stupid bug...

	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Use
	AF_LatinMetricsRec as the dummy metrics because we cast the metrics
	to it later in `af_latin_hints_link_segments'.

2006-02-11  Chia-I Wu  <b90201047@ntu.edu.tw>

	* include/freetype/config/ftoption.h (AF_CONFIG_OPTION_CJK): #define
	to enable autofit CJK script support.  (#define'd by default.)

	* src/autofit/aflatin.h (AF_LATIN_CONSTANT): New macro.

	* src/autofit/aflatin.c (af_latin_metrics_init_widths): Make sure
	that `edge_distance_threshold' is always set.
	(af_latin_hints_link_segments): Potential divide-by-zero bug.
	Use latin constant in the scoring formula.

	* src/autofit/afcjk.c: Minor updates due to the above three changes.

	* docs/TODO, docs/CHANGES: Updated.

2006-02-09  Chia-I Wu  <b90201047@ntu.edu.tw>

	Introduce experimental autofit CJK module based on akito's autohint
	patch.  You need to #define AF_MOD_CJK in afcjk.c to enable it.

	* src/autofit/afglobal.c, src/autofit/afcjk.h, src/autofit/afcjk.c,
	src/autofit/rules.mk, src/autofit/autofit.c, src/autofit/aftypes.h:
	Add CJK module based on akito's autohint patch.

	* src/autofit/afhints.h (AF_SegmentRec): New field `len' for the
	overlap length of the segments.
	(AF_SEGMENT_LEN, AF_SEGMENT_DIST): New macros.

	* src/autofit/aflatin.h (af_latin_metrics_init_widths),
	src/autofit/aflatin.c (af_latin_metrics_init_widths): Made
	`FT_LOCAL'.
	Use the character given by the caller.
	(af_latin_metrics_init_widths, af_latin_hints_link_segments): Scale
	the thresholds.

	* src/autofit/afloader.c (af_loader_load_g): Respect
	AF_SCALER_FLAG_NO_ADVANCE.

2006-02-09  Werner Lemberg  <wl@gnu.org>

	* src/cid/cidparse.c (cid_parse_new): Remove shadowing variable.

2006-02-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* src/cid/cidparse.c (cid_parse_new): Fix for abnormally short or
	broken CIDFont.  Reported by Taek Kwan(TK) Lee (see ft-devel
	2005-11-02).

2006-02-08  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.ac: Fix bug for `--with-old-mac-fonts'
	option on UNIX platform.  It has been broken since 2006-01-11.

2006-02-01  Werner Lemberg  <wl@gnu.org>

	* src/otvalid/module.mk: s/otvalid_module_class/otv_module_class/.
	* src/gxvalid/module.mk: s/gxvalid_module_class/gxv_module_class/.

	* builds/unix/unixddef.mk: Actually do define PLATFORM (fixing
	change from 2006-01-31).
	(TOP_DIR, OBJ_DIR): Update.

	* builds/unix/install.mk (install): Fix path for ftmodule.h.

	* Makefile, *.mk, builds/unix/unix-cc.in, builds/unix-def.in: Use
	`?=' where appropriate.

	* builds/detect.mk (TOP_DIR), builds/os2/os2-dev.mk (TOP_DIR),
	builds/win32/w32-dev.mk (TOP_DIR): Removed.  Defined elsewhere.

2006-01-31  Werner Lemberg  <wl@gnu.org>

	Implement new, simplified module selection.  With GNU make it is now
	sufficient to modify a single file, `modules.cfg', to control the
	inclusion of modules and base extension files.

	This change also fixes the creation of ftmodule.h; it now depends on
	`modules.cfg' and thus is rebuilt only if necessary.

	Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
	default location.

	* modules.cfg: New file.

	* builds/freetype.mk: Don't include `modules.mk'.
	Include all `rules.mk' files as specified in `modules.cfg'.
	(FTOPTION_FLAG, FTOPTION_H): New variables.
	(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
	Add FTOPTION_FLAG.
	($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
	(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
	(INCLUDES): Add DEVEL_DIR.
	(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
	OBJ_M, OBJ_S): Use `:=', not `='.
	(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
	(distclean): Add remove_ftmodule_h.

	* builds/modules.mk: (MODULE_LIST): Removed.
	(make_module_list, clean_module_list): Replace targets
	with...
	(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
	variables.  Reason for the change is that it is not possible to have
	a phony prerequisite which is run only if the target file must be
	rebuilt (phony prerequisites act like subroutines and are *always*
	executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
	changed.
	Update all callers.
	($FTMODULE_H)): Rule to create `ftmodule.h', depending on
	`modules.cfg'.

	* builds/toplevel.mk: Rewrite and simplify module handling.
	(MODULES_CFG, FTMODULE_H): New variables.
	Include MODULES_CFG.
	(MODULES): New variable to include all `module.mk' and `rules.mk'
	files.  We no longer use make's `wildcard' function for this.

	* Makefile (USE_MODULES): Remove.  Update all users.
	(OBJ_DIR): Define it here.

	* src/*/module.mk: Change

	    make_module_list: foo
	    foo: ...

	to

	    FTMODULE_H_COMMANDS += FOO
	    define FOO
	    ...
	    endef

	in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

	* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

	* builds/unix/detect.mk (setup): Always execute `configure' script.
	(have_mk): Rename to...
	(have_Makefile): This.
	Don't use `strip' function.

	* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
	defined.
	(have_mk): Don't use `strip' function.
	Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
	accordingly).

	* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

	* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
	builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
	BUILD_DIR but DEVEL_DIR for development header files.

	* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
	builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
	(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

	* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
	builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

	* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
	development header files.
	Don't define PLATFORM.

	* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
	Update snippet taken from autoconf's m4sh.m4 to current CVS version.
	Be more verbose.

	* include/freetype/config/ftmodule.h: Add comments -- this file is
	no longer used if FreeType is built with GNU make.

	* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
	docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
	Other minor updates.

	* modules.txt: Removed.  Contents included in `modules.cfg'.


	* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
	FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

	* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
	FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
	[FT_STRICT_ALIASING]: Implement.

2006-01-31  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c
	(cid_face_init), src/pfr/pfrobjs.c (pfr_face_init),
	src/type1/t1objs.c (T1_Face_Init): Set face->height to MAX(1.2 *
	units_per_EM, ascender - descender).

2006-01-31  Chia-I Wu  <b90201047@ntu.edu.tw>

	* include/freetype/internal/t1types.h (AFM_FontInfo),
	src/psaux/afmparse.c, src/tools/test_afm.c: Read `FontBBox',
	`Ascender', and `Descender' from an AFM.

	* src/type1/t1afm.c (T1_Read_Metrics): Use the metrics from the AFM.

	* include/freetype/freetype.h (FT_FaceRec): Mention that fields may
	be changed after file attachment.

2006-01-28  Werner Lemberg  <wl@gnu.org>

	* src/*/module.mk (.PHONY): Add.

2006-01-27  Werner Lemberg  <wl@gnu.org>

	* README, docs/FTL.TXT: Fix email address for bug reports.
	Other minor formatting.

	* devel/ftoption.h: Synchronize with
	include/freetype/config/ftoption.h.

2006-01-27  David Turner  <david@freetype.org>

	* builds/unix/configure.ac: Fix build problem on Cygwin.

	* builds/unix/install.mk (install): Don't install the internal
	headers, and remove existing ones if found in the target install
	directory.

	* src/autofit/afwarp.c: Add simple #ifdef to prevent compilation
	if the warp hinter isn't active (it shouldn't, still experimental).

	* Jamfile, include/freetype/config/ftmodule.h: Remove `gxvalid'
	and `otvalid' from the list of modules that are linked statically
	to a given FreeType library.  Functionality has been moved to the
	`ftvalid' CVS module.

	Note also that current Make-based build system still compiles the
	modules though.

	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): New macro
	which controls the definitions of the memory management functions to
	avoid warnings with recent versions of GCC.  This macro is only here
	to be disabled, in case we detect problems with the new scheme.

	NOTE: Disable macro to use the memory debugger -- this will be fixed
	      later!

	* include/freetype/internal/ftmemory.h, src/base/ftutil.c (FT_Alloc,
	FT_QAlloc, FT_Realloc, FT_QRealloc, FT_Free) [FT_STRICT_ALIASING]:
	New versions.


	* builds/win32/visualc/freetype.dsp: Updating project file to
	define FT2_BUILD_LIBRARY, and remove gxvalid + otvalid modules from
	compilation.


	* builds/freetype.mk (FT_CFLAGS), Jamfile (DEFINES): Define the
	macro FT2_BUILD_LIBRARY when compiling the library.

	* include/freetype/config/ftheader.h: Remove inclusions of internal

	src/otvalid/otvgpos.c (otv_x_sxy): Fix debugging information.


	Get rid of writable static variables (i.e., the string table) in
	afmparse, and fix compilation in FT2_MULTI mode.

	* src/psaux/afmparse.c: Include ft2build.h and FT_FREETYPE_H.

	FT_REQUEST_HEIGHT): New macros to get the width and height of a
	request, in fractional pixels.

	* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
	FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
	FT_Request_Metrics): New base functions to set the font metrics.  They
	were part of FT_Select_Size/FT_Request_Size and are made independent
	functions so that metrics are not set again and again.

	* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
	only when driver's size_select/size_request is NULL.  That is, drivers
	should set the metrics themselves.
	(FT_Match_Size): Round before matching.  This was what we did and it
	does cause some problems without rounding.

	* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
	(tt_size_select): Set the font metrics.
	s/index/strike_index/.
	The scaled metrics are always preferred over strikes' metrics, even
	when some strike is selected.  This is done because the strikes'
	metrics are not reliable, e.g., the sign of the descender is wrong for
	some fonts.

	* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
	(tt_size_request): Set the font metrics.
	Call cff_size_select/tt_size_select when some strike is matched.

	src/pcf/pcfdrivr.c, src/truetype/ttdriver.c, src/type1/t1objs.c,
	src/type1/t1objs.h, src/type42/t42objs.c, src/winfonts/winfnt.c:
	Set the font metrics.
	s/index/strike_index/.

	* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
	files were committed.  Just a catch-up.
	(PS_Conv_ToFixed): Remove the `goto'.
	(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.

	* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
	tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
	(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
	advertised metrics in `available_sizes' are different from those
	actually used.

2006-01-23  Chia-I Wu  <b90201047@ntu.edu.tw>

	* src/psaux/psaux.c src/psaux/psauxmod.c src/type1/t1driver.c: Make

	* src/base/ftmac.c (FT_New_Face_From_Suitcase): Count scalable faces
	in supported formats (sfnt, LWFN) only, and ignore bitmap faces in
	unsupported formats (fbit, NFNT).  The number of available faces are
	passed via face->num_faces.  If bitmap faces are embedded in sfnt
	resource, face->num_fixed_size is correctly set.  In public API,
	FT_New_Face() and FT_New_Face_From_FSSpec() count the faces as
	FT_GetFile_From_Mac_Name(), which ignores NFNT resources.

2005-12-13  David Turner  <david@freetype.org>

	Change the implementation of the LIGHT hinting mode to completely
	disable horizontal hinting.  This is an experimental effort to
	integrate David Chester's latest patch without affecting the other
	hinting modes as well.

	Note that this doesn't force auto-hinting for all fonts, however.

	* src/autofit/afhints.c (af_glyph_hints_reload): Don't set
	scaler_fiags here but...
	(af_glyph_hints_rescale): Here.

	hinting for `light' hinting mode.


	* Jamfile: Small fix to ensure that ftexport.sym is placed into the
	same location as other generated objects (i.e., within the `objs'
	directory of the current directory).


	Add support for an embedded `BDF ' table within SFNT-based bitmap
	font files.  This is used to store atoms & properties from the
	original BDF fonts that were used to generate the font file.

	The feature is controlled by TT_CONFIG_OPTION_BDF within
	`ftoption.h' and is used to implement FT_Get_BDF_Property for these
	font files.

	At the moment, this is still experimental, the BDF table format
	isn't cast into stone yet.

	Also, if all segments have offset 0, glyph_ids is always invalid.
	It does not cause any problem so far only because the check misses
	equality.
	Distinguish between unsorted and overlapping segments.
	(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions
	to do `charcode => glyph index' by linear/binary search.

	font to have no `head' table if tables `SING' and `META' are
	present; this is to support `SING Glyphlet'.

	`SING Glyphlet' is an extension to OpenType developed by Adobe
	primarily to facilitate adding supplemental glyphs to an OpenType
	font (with emphasis on, but not necessariy limited to, gaiji to a
	CJK font).  A SING Glyphlet Font is an OpenType font that contains
	the outline(s), either in a `glyf' or `CFF' table, for a glyph;
	`cmap', `BASE', and `GSUB' tables are present with the same format
	and functionaliy as a regular OpenType font; there are no `name',
	`head', `OS/2', and `post' tables; there are two new tables, `SING'
	which contains details about the glyphlet, and `META' which contains
	metadata.

	Further information on the SING Glyphlet format can be found at:

	  http://www.adobe.com/products/indesign/sing_gaiji.html

	* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New

	(TT_LOADER_SET_PP): New macro to calculate and set the four phantom
	points.
	(load_truetype_glyph): Never set exec->glyphSize to 0.  This closes
	Savannah bug #13107.
	Forget glyph frame before calling TT_Process_Simple_Glyph.
	Use TT_LOADER_SET_PP.
	Scale all four phantom points.
	Split off some functionality to ...
	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
	new functions.
