2006-05-03  David Turner  

	Allow compilation again with C++ compilers.

	* include/freetype/internal/ftmemory.h (FT_ASSIGNP,

	FT_ASSIGNP_INNER): New macros which do the actual assignment, and

	which exist in two variants (for C and C++).

	Update callers accordingly.

2006-05-03  Werner Lemberg  

	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Removed.

	`-Wstrict-prototypes'.

	* src/base/ftstream.c (FT_Stream_EnterFrame): Add cast.

	* include/freetype/config/ftconfig.h (FT_BASE_DEF) [__cplusplus]:

	Remove `extern'.

2006-05-02  David Turner  

	Update the memory management functions and macros to safely deal

	with array size buffer overflows.  This corresponds to attempts 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_alloc_debug, ft_mem_qalloc_debug, ft_mem_realloc_debug,

	ft_mem_qrealloc_debug, ft_mem_free_debug): Removed.

	(FT_MEM_ALLOC, FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC,

	FT_MEM_FREE): Redefine.

	(FT_MEM_NEW_ARRAY, FT_MEM_RENEW_ARRAY, FT_MEM_QNEW_ARRAY,

	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.

	* src/base/ftmac.c (read_lwfn): Catch integer overflow.

	* src/base/ftrfork.c (raccess_guess_darwin_hfsplus): Ditto.

	* src/base/ftutil.c: Remove special code for FT_STRICT_ALIASING.

	(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.

2006-04-30  suzuki toshiya  

	* src/base/ftobjs.c (Mac_Read_POST_Resource): Correct pfb_pos

	initialization, remove extra cast to copy to pfb_lenpos.  This fixes

	parsing of PFB fonts with MacOS resource fork (bug introduced

	2003-09-11).  Patch provided by Huib-Jan Imbens .

2006-04-29  Werner Lemberg  

	Further C library abstraction.  Based on a patch from

	msn2@bidyut.com.

	* include/freetype/config/ftstdlib.h (FT_CHAR_BIT, FT_FILE,

	ft_fopen, ft_fclose, ft_fseek, ft_ftell, ft_fread, ft_smalloc,

	ft_scalloc, ft_srealloc, ft_sfree, ft_labs): New wrapper macros for

	C library functions.  Update all users accordingly (and catch some

	Pango (see http://bugzilla.gnome.org/show_bug.cgi?id=327852).

2006-02-25  Werner Lemberg  

	* devel/ftoption.h: Synchronize with

	include/freetype/config/ftoption.h.

	* src/cache/ftccache.c (ftc_node_destroy): Use FT_LOCAL_DEF (again).

2006-02-25  David Turner  

	Fix compiler warnings as well as C++ compilation problems.

	Add missing prototypes.

	* src/autofit/afcjk.c, src/base/ftobjs.c, src/base/ftutil.c,

	src/bdf/bdfdrivr.c, src/cff/cffcmap.c, src/cff/cffobjs.c,

	src/psaux/afmparse.c,, src/psaux/t1cmap.c, src/smooth/ftgrays.c

	src/tools/apinames.c, src/truetype/ttdriver.c: Add various casts,

	initialize variables, and decorate functions with FT_CALLBACK_DEF,

	etc., to fix compiler warnings (and C++ compiling errors).

	* src/cache/ftcbasic.c: Fix `-Wmissing-prototypes' warnings with

	gcc.

	* builds/unix/ftsystem.c: Don't include FT_INTERNAL_OBJECTS_H but

	FT_INTERNAL_STREAM_H.

	* src/base/ftsystem.c: Include FT_INTERNAL_STREAM_H.

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

	* include/freetype/config/ftoption.h (FT_STRICT_ALIASING): Don't

	define for C++.

	* include/freetype/internal/services/svotval.h: Don't include

	FT_OPENTYPE_VALIDATE_H but FT_INTERNAL_VALIDATE_H.

	* include/freetype/internal/services/svpfr.h: Include FT_PFR_H.

	* src/gzip/ftgzip.c: Include FT_GZIP_H.

	* src/lzw/ftlzw.c, src/lzw/ftlzw2.c: Include FT_LZW_H.

	* src/sfnt/ttbdf.c (tt_face_load_bdf_props): Rearrange code.

2006-02-24  Chia-I Wu  

	* src/base/ftoutln.c (FT_OUTLINE_GET_CONTOUR, ft_contour_has,

	ft_contour_enclosed, ft_outline_get_orientation): Commented out.  We

	have to wait until `FT_GlyphSlot_Own_Bitmap' is stabilized.

	(FT_Outline_Embolden): Use `FT_Outline_Get_Orientation'.

2006-02-24  Chia-I Wu  

	* include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Update

	documentation.

	* include/freetype/ftsynth.h (FT_GlyphSlot_Own_Bitmap),

	src/base/ftsynth.c (FT_GlyphSlot_Own_Bitmap): New function to make

	sure a glyph slot owns its bitmap.  It is also marked experimental

	and due to change.

	(FT_GlyphSlot_Embolden): Undo the last change.  It turns out that

	rendering the outline confuses some applications.

2006-02-24  David Turner  

	* Release candidate VER-2-2-0-RC3.

	----------------------------------

	* src/cache/ftcbasic.c: Correct compatibility hack bug.

2006-02-24  Chia-I Wu  

	* include/freetype/freetype.h (FT_Size_RequestRec): Change the type

	of `width' and `height' to `FT_Long'.

	(enum FT_Size_Request_Type), src/base/ftobjs.c (FT_Request_Metrics):

	New request type `FT_SIZE_REQUEST_TYPE_SCALES' to specify the scales

	directly.

2006-02-23  David Turner  

	Two BDF patches from Debian libfreetype6 for 2.1.10.

	* src/bdf/bdflib.c (_bdf_parse_glyphs): Fix a bug with zero-width

	glyphs.

	Fix a problem with large encodings.

	Fix binary compatibility issues for gnustep-back (GNUstep backend

	module) which still crashes under Sarge.

	* 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.

	* src/cache/ftcbasic.c: Fix a silly bug that prevented our `hack' to

	support rogue clients compiled against 2.1.7 to work correctly.

	This probably explains the GNUstep crashes with the second release

	candidate.

2006-02-23  Chia-I Wu  

	* 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  

	* 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  

	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  

	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  

	* 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  

	* devel/ftoption.h: Synchronize with

	include/freetype/config/ftoption.h.

2006-02-16  David Turner  

	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,

	include/freetype/internal/t1types.h,

	include/freetype/internal/tttypes.h, src/base/ftcalc.c,

	src/base/ftdbgmem.c, src/base/ftobjs.c, src/base/ftutil.c,

	src/bdf/bdfdrivr.c, src/cache/ftccache.c, src/cache/ftccback.h,

	src/cache/ftcmanag.c, src/cff/cffdrivr.c, src/cid/cidriver.c,

	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  

	* 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  

	* 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  

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

2006-02-14  Chia-I Wu  

	* 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  

	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  

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

	code...

2006-02-13  Chia-I Wu  

	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  

	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  

	* 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  

	* 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  

	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  

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

2006-02-09  suzuki toshiya  

	* 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  

	* 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  

	* 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  

	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.
