  	[ftraster] Fix rendering.
  
  	Problem reported by Tom Bishop <wenlin@wenlin.com>; see
  	thread starting with
  
  	  http://lists.gnu.org/archive/html/freetype/2010-10/msg00049.html
  
  	* src/raster/ftraster.c (Line_Up): Replace FMulDiv with SMulDiv
  	since the involved multiplication exceeds 32 bits.
  
  2010-10-25  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Revert a change of `_idx' type in FTC_CACHE_LOOKUP_CMP().
  
  	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Revert
  	the type of `_idx' from FT_PtrDist (by previous change)
  	to original FT_UFast, to match with FT_CacheRec.
  
  2010-10-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[cache] Change the hash types to FT_PtrDist.
  
  	On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
  	variables are inappropriate to calculate hash values
  	from the memory address (64-bit).  The hash variables  
  	are extended from FT_ULong to FT_PtrDist and new
  	hashing macro functions are introduced.  The hash
  	values on 16-bit memory platforms are changed, but
  	ILP32 and LP64 are not changed.  The hash value in
  	the cache subsystem is not reverted to the memory
  	address, so using signed type FT_PtrDist is safe.
  
  	* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
  	function to replace FTC_FACE_ID_HASH() for portability.
  	* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace 
  	FTC_FACE_ID_HASH() by _FTC_FACE_ID_HASH().
  	* src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
  
  	* src/cache/ftccache.h (FTC_NodeRec): The type of the
  	member `hash' is changed from FT_UInt32 to FT_PtrDist.
  
  	* src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
  	argument `hash' is changed from FT_UInt32 to FT_PtrDist.
  	(FTC_Cache_NewNode): Ditto.
  	* src/cache/ftccache.c (ftc_cache_add): Ditto.
  	(FTC_Cache_Lookup): Ditto.  (FTC_Cache_NewNode): Ditto.
  	* src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
  	* src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
  
  	* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
  	of the internal variable `hash' is changed to FT_PtrDist
  	from FT_UInt32.  (FTC_ImageCache_LookupScaler): Ditto.
  	(FTC_SBitCache_Lookup): Ditto.
  	(FTC_SBitCache_LookupScaler): Ditto.
  	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
  	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
  	Also the type of the internal variable `_idx' is changed to
  	FT_PtrDist from FT_UFast for better pointer calculation.
  	
  2010-10-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[cache] Hide internal macros incompatible with LLP64.
  
  	FT_POINTER_TO_ULONG(), FTC_FACE_ID_HASH() and
  	FTC_IMAGE_TYPE_HASH() are enclosed by
  	FT_CONFIG_OPTION_OLD_INTERNALS and hidden from
  	normal clients.
  
  	For the history of these macros, see the investigation:
  	http://lists.gnu.org/archive/html/freetype/2010-10/msg00022.html
  
  2010-10-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Change the type of FT_MEM_VAL() from FT_ULong to FT_PtrDist.
  
  	On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
  	cannot cover the memory address (64-bit).  FT_MEM_VAL() is
  	used for hashing only and not dereferred, so using signed
  	type FT_PtrDist is safe.
  
  	* src/base/ftdbgmem.c (FT_MEM_VAL): Change the type of the
  	return value from FT_ULong to FT_PtrDist.
  	(ft_mem_table_resize): The type of hash is changed to
  	FT_PtrDist.  (ft_mem_table_get_nodep): Ditto.
  
  2010-10-24  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Replace "%lx" for memory address by "%p", LLP64 platforms.
  
  	On LLP64 platforms (e.g. Win64), long (32-bit) cannot cover
  	the memory address (64-bit).  Also the casts from the pointer
  	type to long int should be removed to preserve the address
  	correctly.
  
  	* src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".
  	(End_Profile) Ditto.
  	* src/truetype/ttinterp.c (Init_Context): Ditto.
  
  2010-10-15  Alexei Podtelezhnikov  <apodtele@gmail.com>
  
  	Fix thinko in spline flattening.
  
  	FT_MAX_CURVE_DEVIATION is dependent on the value of ONE_PIXEL.
  
  	* src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): Remove it and
  	replace it everywhere with ONE_PIXEL/8.
  
  2010-10-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[raccess] Skip unrequired resource access rules by Darwin VFS.
  
  	When a resource fork access rule by Darwin VFS could open the
  	resource fork but no font is found in it, the rest of rules
  	by Darwin VFS are skipped.  It reduces the warnings of the
  	deprecated resource fork access method by recent Darwin kernel.
  	Fix MacPorts ticket #18859:
  		http://trac.macports.org/ticket/18859
  
  	* src/base/ftobjs.c (load_face_in_embedded_rfork):
  	When FT_Stream_New() returns FT_Err_Cannot_Open_Stream, it
  	means that the file is possible to be fopen()-ed but zero-sized.
  	Also there is a case that the resource fork is not zero-sized, 
  	but no supported font exists in it.  If a rule by Darwin VFS
  	falls into such cases, there is no need to try other Darwin VFS
  	rules anymore.  Such cases are marked by vfs_rfork_has_no_font.
  	If it is TRUE, the Darwin VFS rules are skipped.
  
  2010-10-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[raccess] Grouping resource access rules based on Darwin VFS.
  
  	MacOS X/Darwin kernel supports a few tricky methods to access
  	a resource fork via ANSI C or POSIX interface.  Current resource
  	fork accessor tries all possible methods to support all kernels.
  	But if a method could open a resource fork but no font is found,
  	there is no need to try other methods older than tested method. 
  	To determine whether the rule index is for Darwin VFS, a local
  	function ftrfork.c::raccess_rule_by_darwin_vfs() is introduced.
  	To use this function in ftobjs.c etc but it should be inlined,
  	it is exposed by ftbase.h.
  
  	* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
  	the rules to access the resource fork.
  	(raccess_guess_rec): New structure to bind the rule function and
  	rule enum type.
  	(FT_Raccess_Guess): The list of the rule functions is replaced by
  	(raccess_guess_table): This.  This is exposed to be used by other
  	intra module functions.
  	(raccess_rule_by_darwin_vfs): A function to return a boolean
  	if the rule specified by the rule index is based on Darwin VFS.
  
  2010-10-13  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Prevent to open a FT_Stream for zero-sized file on non-Unix.
  
  	builds/unix/ftsystem.c prevents to open an useless stream from
  	zero-sized file and returns FT_Err_Cannot_Open_Stream, but the
  	stream drivers for ANSI C, Amiga and VMS return useless streams.
  	For cross-platform consistency, all stream drivers should act
  	same.
  
  	* src/base/ftsystem.c (FT_Stream_Open): If the size of the opened
  	file is zero, FT_Err_Cannot_Open_Stream is returned.
  	* builds/amiga/src/base/ftsystem.c (FT_Stream_Open): Ditto.
  	* src/vms/ftsystem.c (FT_Stream_Open): Ditto.
  
  2010-10-12  Werner Lemberg  <wl@gnu.org>
  
  	Fix Savannah bug #31310.
  
  	* src/truetype/ttgxvar.c (ft_var_readpackedpoints): Protect against
  	invalid `runcnt' values.
  
  2010-10-08  Chris Liddell  <chris.liddell@artifex.com>
  
  	Fix Savannah bug #31275.
  
  	* src/sfnt/ttpost.c: Include FT_INTERNAL_DEBUG_H.
  
  2010-10-06  Werner Lemberg  <wl@gnu.org>
  
  	[truetype] Improve error handling of `SHZ' bytecode instruction.
  	Problem reported by Chris Evans <scarybeasts@gmail.com>.
  
  	* src/truetype/ttinterp.c (Ins_SHZ): Check `last_point'.
  
  2010-10-05  Werner Lemberg  <wl@gnu.org>
  
  	Fix Savannah bug #31253.
  	Patch submitted by an anonymous reporter.
  
  	* configure: Use `awk' instead of `sed' to manipulate output of `ls
  	-id'.
  
  2010-10-03  Werner Lemberg  <wl@gnu.org>

  	(TT_RunIns): Updated.
  
  2010-09-20  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[sfnt] Make error message filling NULL names less verbose.
  
  	* src/sfnt/ttpost.c (load_format_20): Showing 1 summary message
  	when we fill `post' names by NULL, instead of per-entry message.
  
  2010-09-20  Graham Asher  <graham.asher@btinternet.com>
  	    David Bevan  <david.bevan@pb.com>
  
  	[smooth] Fix and improve spline flattening.
  
  	This fixes the flattening of cubic, S-shaped curves and speeds up
  	the handling of both the conic and cubic arcs.
  
  	See the discussions on the freetype-devel mailing list in late
  	August and September 2010 for details.
  
  	* src/smooth/ftgrays.c (FT_MAX_CURVE_DEVIATION): New macro.
  	(TWorker): Remove `conic_level' and `cubic_level' elements.
  	(gray_render_conic): Simplify algorithm.
  	(gray_render_cubic): New algorithm; details are given in the code
  	comments.
  	(gray_convert_glyph): Remove heuristics.
  
  2010-09-19  Werner Lemberg  <wl@gnu.org>
  
  	Minor fixes.
  
  	* src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]'
  	is `FT_UShort'.
  	(cff_index_access_element): Don't use additions in comparison.
  	* src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type

  	`FT_Long'.
  
  2010-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[cff] Truncate the element length at the end of the stream.
  	See Savannah bug #30975.
  
  	* src/cff/cffload.c (cff_index_access_element): `off2', the offset
  	to the next element is truncated at the end of the stream to prevent
  	invalid I/O.  As `off1', the offset to the requested element has
  	been checked by FT_STREAM_SEEK(), `off2' should be checked
  	similarly.
  
  2010-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[cff] Ignore CID > 0xFFFFU.
  	See Savannah bug #30975.
  
  	* src/cff/cffload.c (cff_charset_compute_cids): Ignore CID if
  	greater than 0xFFFFU.  CFF font spec does not mention maximum CID in
  	the font, but PostScript and PDF spec define that maximum CID is
  	0xFFFFU.
  
  2010-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[cff] Make trace message in cff_charset_load() verbose.
  	See Savannah bug #30975.
  
  	* src/cff/cffload.c (cff_charset_load): Report the original `nleft'
  	and truncated `nleft'.
  
  2010-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[cff] Correct `max_cid' from CID array length to max CID.
  	See Savannah bug #30975.
  
  	* src/cff/cffload.c (cff_charset_compute_cids): Don't increment
  	max_cid after detecting max CID.  The array CFF_Charset->cids is
  	allocated by max_cid + 1.
  	(cff_charset_cid_to_gindex): Permit CID is less than or equal to
  	CFF_Charset->max_cid.
  	* src/cff/cffobjs.c (cff_face_init): FT_Face->num_glyphs is
  	calculated as CFF_Charset->max_cid + 1.
  
  2010-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[truetype] Sanitize the broken offsets in `loca'.
  	See Savannah bug #31040.
  
  	* src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
  	offset to the requested entry in `glyf' exceeds the end of the
  	table, return offset=0, length=0.  If `pos2', the offset to the next
  	entry in `glyf' exceeds the end of the table, truncate the entry
  	length at the end of `glyf' table.
  
  2010-09-19  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[sfnt] Prevent overrunning in `post' table parser.
  	See Savannah bug #31040.
  
  	* src/sfnt/ttpost.c (load_post_names): Get the length of `post'
  	table and pass the limit of `post' table to load_format_20() and
  	load_format_25().
  	(load_format_20): Stop the parsing when we reached at the limit of
  	`post' table.  If more glyph names are required, they are filled by
  	NULL names.
  
  2010-09-17  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[truetype] Don't duplicate size->twilight structure to be freed.
  	See Savannah bug #31040 for detail.
  
  	* src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
  	FT_GlyphZoneRec size->twilight to be freed.  If duplicated,
  	FT_FREE() erases the duplicated pointers only and leave original
  	pointers.  They can cause the double-free crash when the burst
  	errors occur in TrueType interpreter and free_buffer_in_size() is
  	invoked repeatedly.
  
  2010-09-15  Werner Lemberg  <wl@gnu.org>
  
  	Make bytecode debugging with FontForge work again.
  
  	* src/truetype/ttinterp.c (TT_RunIns): Don't call
  	`free_buffer_in_size' in case of error if a debugger is active.
  
  2010-09-14  Werner Lemberg  <wl@gnu.org>
  
  	Improve tracing messages.
  
  	* src/truetype/ttinterp.c (TT_RunIns): Improve wording of tracing
  	message.
  	* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Add
  	tracing message.
  	* src/truetype/ttgload.c (tt_loader_init): Add tracing message.
  	* src/cache/ftcsbits.c (ftc_snode_load): Emit tracing message if
  	glyph doesn't fit into a small bitmap container.
  
  2010-09-13  Werner Lemberg  <wl@gnu.org>
  
  	Fix minor issues reported by <muktha.narayan@wipro.com>.
  
  	* src/autofit/aflatin.c (af_latin_compute_stem_width): Remove
  	redundant conditional check.
  	* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
  	* src/cff/cffload.c (cff_encoding_load): Remove conditional check
  	which always evaluates to `true'.
  	* src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points):
  	Ditto.
  	* src/truetype/ttinterp.c (Ins_IUP): Ditto.
  	* src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if
  	value is already dereferenced.
  	* src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
  
  2010-08-31  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Ignore the environmental setting of LIBTOOL.
  	Patch is suggested by Adrian Bunk, to prevent unexpected
  	reflection of environmental LIBTOOL.  See:
  	http://savannah.nongnu.org/patch/?7290
  
  	* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
  	$(FT_LIBTOOL_DIR)/libtool.  FT_LIBTOOL_DIR is set to $(BUILD_DIR)
  	by default.
  	* configure: When configured for the building out of source tee,
  	FT_LIBTOOL_DIR is set to $(OBJ_DIR).
  
  2010-08-31  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[truetype] Decrease the trace level catching the interpreter error.
  
  	* src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
  	showing the error when the interpreter returns with an error,
  	from FT_TRACE7() to FT_TRACE1().
  
  2010-08-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	[truetype] Prevent bytecode reuse after the interpretation error.
  
  	* src/truetype/ttinterp.c (free_buffer_in_size): New function to
  	free the buffer allocated during the interpretation of this glyph.
  	(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
  	an error occurs in the bytecode interpretation.  The interpretation
  	of invalid bytecode may break the function definitions and referring
  	them in later interpretation is danger.  By unsetting these flags,
  	`fpgm' and `prep' tables are executed again in next interpretation.
  
  	This fixes Savannah bug #30798, reported by Robert Święcki.
  
  2010-08-29  Werner Lemberg  <wl@gnu.org>
  
  	[ftraster] Pacify compiler.
  
  	* src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is
  	not used.
  
  2010-08-29  Werner Lemberg  <wl@gnu.org>
  
  	[cff] Allow SIDs >= 65000.
  
  	* src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
  	The threshold for SIDs is not applicable here.  I misinterpreted the
  	`SID values 65000 and above are available for implementation use'
  	sentence in the CFF specification.
  
  	Problem reported by Ivan Ninčić <inincic@pdftron.com>.
  
  2010-08-28  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Force hinting when the font lacks its familyname.
  
  	In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
  	stream may lack `name' table because they are not required.  Hinting
  	for nameless fonts is safer for PDFs including embedded Chinese
  	fonts.  Written by David Bevan, see:
  
  	http://lists.gnu.org/archive/html/freetype-devel/2010-08/msg00021.html
  	http://lists.freedesktop.org/archives/poppler/2010-August/006310.html
  
  	* src/truetype/ttobjs.c (tt_check_trickyness): If a NULL pointer by
  	nameless font is given, TRUE is returned to enable hinting.
  
  2010-08-28  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
  
  	Register yet another tricky TrueType font.
  
  	* src/truetype/ttobjs.c (tt_check_trickyness): Add `HuaTianKaiTi?',
  	a Kaishu typeface paired with `HuaTianSongTi?' by Huatian
  	Information Industry.
  
  2010-08-17  Teijo Kinnunen <Teijo.Kinnunen@nuance.com>
  
  	Fix Savannah bug #30788.
  
  	* src/cache/ftccache.c (FTC_Cache_Clear): Check `cache->buckets' for
  	NULL too.
  
  2010-08-10  Werner Lemberg  <wl@gnu.org>
  
  	Try to fix Savannah bug #30717 (and probably #30719 too).
  
  	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Add another
  	overflow test for `width' and `height'.
  
  2010-08-06  Werner Lemberg  <wl@gnu.org>
  
  	* Version 2.4.2 released.

  	Additional fix for Savannah bug #30306.
  
  	* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the
  	POST fragment is 0, the segment is completely ignored.  The declared
  	length of the segment is not cared at all.  According to Adobe
  	Technical Note 5040, type 0 segment is a comment only and should not

  2010-05-10  Ken Sharp  <ken.sharp@artifex.com>
  
  	Fix Savannah bug #29846.
  
  	Previously we discovered fonts which used `setcurrentpoint' to set
  	the initial point of a contour to 0,0.  This caused FreeType to
  	raise an error, because the `setcurrentpoint' operator is only
  	supposed to be used with the results from an OtherSubr subroutine.
  
  	This was fixed by simply ignoring the error and carrying on.
  
  	Now we have found a font which uses setcurrentpoint to actually
  	establish a non-zero point for a contour during the course of a
  	glyph program.  FWIW, these files may be produced by an application
  	called `Intaglio' on the Mac, when converting TrueType fonts to
  	Type 1.
  
  	The fix allows the new invalid behaviour, the old invalid behaviour
  	and real proper usage of the operator to work the same way as Adobe
  	interpreters apparently do.
  
  	(t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top
  	two elements of the stack to establish unconditionally the current x
  	and y coordinates.
  
  	Make the `flex' subroutine handling (OtherSubr 0) put the current
  	x,y coordinates onto the stack, instead of two dummy uninitialised
  	values.
