	[cache] Fix an off-by-one bug in FTC_Manager_RemoveFaceID().
	Found by <ychen1392001@yahoo.com.cn>, see detail in

	  http://lists.gnu.org/archive/html/freetype/2011-01/msg00023.html

	* src/cache/ftccache.c (FTC_Cache_RemoveFaceID): Check the node
	buckets[cache->p + cache->mask] too.

2011-02-19  Kevin Kofler  <kevin.kofler@chello.at>

	Fall back to autohinting if a TTF/OTF doesn't contain any bytecode.
	This is Savannah patch #7471.

	* src/base/ftobjs.c (FT_Load_Glyph): Implement it.

2011-02-19  John Tytgat  <John.Tytgat@esko.com>

	[cff] Fix subset prefix removal.
	This is Savannah patch #7465.

	* src/cff/cffobjs.c (remove_subset_prefix): Update length after
	subset prefix removal.

2011-02-13  Bradley Grainger  <bgrainger@logos.com>

	Add inline assembly version of FT_MulFix for MSVC.

	* include/freetype/config/ftconfig.h: Ported the FT_MulFix_i386
	function from GNU inline assembly syntax (see #ifdef __GNUC__ block
	above) to MASM syntax for Microsoft Visual C++.

2011-02-13  Bradley Grainger  <bgrainger@logos.com>

	Add project and solution files in Visual Studio 2010 format.

	* builds/win32/.gitignore: Ignore user-specific cache files.
	* builds/win32/vc2010/: Add VS2010 project & solution files, created
	by upgrading builds/win32/vc2008/freetype.vcproj.
	* objs/.gitignore: Ignore Visual Studio output files.

2011-02-01  Werner Lemberg  <wl@gnu.org>

	* src/autofit/afdummy.c: Include `aferrors.h'.
	Problem reported by Chris Liddel <chris.liddell@artifex.com>.

2011-02-01  Werner Lemberg  <wl@gnu.org>

	[cff] Ignore unknown operators in charstrings.
	Patch suggested by Miles.Lau <sunliang_liu@foxitsoftware.com>.

	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Emit tracing
	message for unknown operators and continue instead of exiting with a
	syntax error.

2011-02-01  Werner Lemberg  <wl@gnu.org>

	[truetype] FT_LOAD_PEDANTIC now affects `prep' and `fpgm' also.

	* src/truetype/ttgload.c (tt_loader_init): Handle
	`FT_LOAD_PEDANTIC'.
	* src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep,
	tt_size_init_bytecode, tt_size_ready_bytecode): New argument to
	handle pedantic mode.
	* src/truetype/ttobjs.h: Updated.

2011-01-31  Werner Lemberg  <wl@gnu.org>

	[truetype] Protect jump instructions against endless loops.

	* src/truetype/interp.c (DO_JROT, DO_JMPR, DO_JROF): Exit with error
	if offset is zero.

2011-01-31  Werner Lemberg  <wl@gnu.org>

	[truetype] Improve handling of invalid references.

	* src/truetype/interp.c: Set even more TT_Err_Invalid_Reference
	error codes only if pedantic hinting is active.  At the same time,
	try to provide sane values which hopefully allow useful
	continuation.  Exception to this is CALL and LOOPCALL – due to
	possible stack corruption it is necessary to bail out.

2011-01-31  Werner Lemberg  <wl@gnu.org>

	[truetype] Improve handling of stack underflow.

	* src/truetype/ttinterp.c (TT_RunIns, Ins_FLIPPT, Ins_DELTAP,
	Ins_DELTAC): Exit with error only if `pedantic_hinting' is set. 
	Otherwise, try to do something sane.

2011-01-30  Werner Lemberg  <wl@gnu.org>

	* src/sfnt/ttmtx.c (tt_face_load_hmtx): Fix tracing message.

2011-01-30  LIU Sun-Liang  <sunliang_liu@foxitsoftware.com>

	[truetype]: Fix behaviour of MIAP for invalid arguments.

	* src/truetype/ttinterp.c (Ins_MIAP): Set reference points even in
	case of error.

2011-01-18  Werner Lemberg  <wl@gnu.org>

	[truetype] Fix handling of MIRP instruction.

	Thanks to Greg Hitchcock who explained the issue.

	* src/truetype/ttinterp.c (Ins_MIRP): Replace a `>=' operator with
	`>' since the description in the specification is incorrect.
	This fixes, for example, glyph `two' in font `Helvetica Neue LT Com
	65 medium' at 15ppem.

2011-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Fix ARM assembly code in include/freetype/config/ftconfig.h.

	* include/freetype/config/ftconfig.h (FT_MulFix_arm):
	Copy the maintained code from builds/unix/ftconfig.in.
	Old GNU binutils could not accept the reduced syntax
	`orr %0, %2, lsl #16'.  Un-omitted syntax like RVCT,
	`orr %0, %0, %2, lsl #16' is better.  Reported by
	Johnson Y. Yan.  The bug report by Qt developers is
	considered too.

	http://bugreports.qt.nokia.com/browse/QTBUG-6521

2011-01-15  Werner Lemberg  <wl@gnu.org>

	[raster] Make bbox handling the same as with Microsoft's rasterizer.

	Right before B/W rasterizing, the bbox gets simply rounded to
	integers.  This fixes, for example, glyph `three' in font `Helvetica
	Neue LT Com 65 Medium' at 11ppem.

	Thanks to Greg Hitchcock who explained this behaviour.

	* src/raster/ftrend1.c (ft_raster1_render): Implement it.

2011-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.

	* builds/unix/configure.raw: Consider recent gcc-standard
	flags to specify architecture in CFLAGS & LDFLAGS
	harmonization.  Requested by Savannah bug #32114, to
	support multilib feature of BuildRoot SDK correctly.

2011-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.

	* builds/unix/configure.raw: Some important options that
	included in CFLAGS but not in LDFLAGS are copied to
	LDFLAGS, but the last option in CFLAGS was not checked.

2011-01-13  Werner Lemberg  <wl@gnu.org>

	[raster] Add undocumented drop-out rule to the other bbox side also.

	* src/raster/ftraster.c (Vertical_Sweep_Drop,
	Horizontal_Sweep_Drop): Implement it.

2011-01-13  Werner Lemberg  <wl@gnu.org>

	[raster] Reduce jitter value.

	This catches a rendering problem with glyph `x' from Tahoma at
	10ppem.  It seems that the increase of the precision in the change
	from 2009-06-11 makes a larger jitter value unnecessary.

	* src/raster/ftraster.c (Set_High_Precision): Implement it.

2011-01-13  Werner Lemberg  <wl@gnu.org>

	[raster] Handle drop-outs at glyph borders according to Microsoft.

	If a drop-out rule would switch on a pixel outside of the glyph's
	bounding box, use the right (or top) pixel instead.  This is an
	undocumented feature, but some fonts like `Helvetica Neue LT Com 65
	Medium' heavily rely on it.

	Thanks to Greg Hitchcock who explained this behaviour.

	* src/raster/ftraster.c (Vertical_Sweep_Drop,
	Horizontal_Sweep_Drop): Implement it.

2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[cache] Fix Savannah bug #31923, patch drafted by Harsha.

	When a node comparator changes the cached nodes during the
	search of a node matching with queried properties, the
	pointers obtained before the function should be updated to
	prevent the dereference to freed or reallocated nodes.
	To minimize the rescan of the linked list, the update is
	executed when the comparator notifies the change of cached
	nodes. This change depends previous change:
	38b272ffbbdaae276d636aec4ef84af407d16181

	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
	top node if the cached nodes are changed.
	* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.

2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[cache] Notice if a cache query induced the node list change.

	Some node comparators (comparing the cache node contents and the
	properties specified by the query) can flush the cache node to
	prevent the cache inflation.  The change may invalidate the pointers
	to the node obtained before the node comparison, so it should be
	noticed to the caller.  The problem caused by the cache node
	changing is reported by Harsha, see Savannah bug #31923.

	* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
	`FT_Bool* list_changed' to indicate the change of the cached nodes
	to the caller.
	(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
	`_list_changed'.
	(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
	and update it when `FTC_Manager_FlushN' flushes any nodes.

	* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
	FTC_Node_CompareFunc type.
	(ftc_gnode_compare): Ditto.

	* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
	TRUE/FALSE macros.
	(ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
	list_changed' to indicate the change of the cache nodes (anyway, it
	is always FALSE).

	* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
	TRUE/FALSE macros.
	(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
	indicate the change of the cache nodes (anyway, it is always FALSE).
	(ftc_cmap_node_remove_faceid): Ditto.

	* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
	`FTC_CACHE_TRYLOOP_END', because the result is not needed.
	(FTC_Cache_Lookup): Watch the change of the cache nodes by
	`list_changed'.
	(FTC_Cache_RemoveFaceID): Ditto.

	* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
	TRUE/FALSE macros.
	(ftc_gnode_compare): New argument `FT_Bool* list_changed' to
	indicate the change of the cache nodes (anyway, it is always FALSE).
	(FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
	passed to `ftc_gnode_compare'.
	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.

	* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
	list_changed' to indicate the change of the cache nodes, anyway.  It
	is updated by `FTC_CACHE_TRYLOOP'.
	(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
	passed to `ftc_snode_compare'.
	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[cache] Fit FTC_GNode_Compare() to FTC_Node_CompareFunc.

	* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
	argument `FTC_Cache  cache' to fit FTC_Node_CompareFunc
	prototype.
	* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
	`cache' is not used by its child ftc_gnode_compare().

2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[cache] Deduplicate the code to get the top node by a hash.

	There are several duplicated code fragments getting the top node
	from a cache by a given hash, like:

	    idx = hash & cache->mask;
	    if ( idx < cache->p )
	      idx = hash & ( cache->mask * 2 + 1 );
	    pnode = cache->buckets + idx;

	To remove duplication, a cpp-macro to do same work
	`FTC_NODE__TOP_FOR_HASH' is introduced.  For non-inlined
	configuration, non-ftc_get_top_node_for_hash() is also introduced.

	* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
	and implement inlined version.
	(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
	* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
	version.
	(ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
	(ftc_node_hash_link): Ditto.
	(FTC_Cache_Lookup): Ditto.

2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[cache] inline-specific functions are conditionalized.

	* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
	inlined configuration.  This function is a thin wrapper of
	`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
	`nodecmp' argument).  Under non-inlined configuration,
	`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
	`FTC_Cache->clazz.node_compare'.

	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
	* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
	`ftc_snode_compare'.
	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.

2011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[cache] Correct a type mismatch under non-inlined config.

	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
	takes the node via a pointer `FTC_Node*', differently from cpp-macro
	`FTC_CACHE_LOOKUP_CMP'.

2011-01-06  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Update Jamfile to include Bzip2 support.

	* Jamfile: Include src/bzip2 to project.
	Comments for lzw, gzip, bzip2 are changed to clarify that
	they are for compressed PCF fonts, not others.
	(e.g. compressed BDF fonts are not supported yet)

2011-01-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Update Symbian project files to include Bzip2 support.

	Currently, it provides FT_Stream_OpenBzip2() that returns
	unimplemented error always, to prevent unresolved symbol
	error for the applications designed for Unix systems.

	* builds/symbian/bld.inf: Include ftbzip2.h.
	* builds/symbian/freetype.mmp: Include ftbzip2.c.

2011-01-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

2011-01-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	Update pkg-config tools to reflect Bzip2 support.

	* builds/unix/freetype-config.in: Include `-lbz2' to
	--libs output, if built with Bzip2 support.
	* builds/unix/freetype2.in: Ditto.

2011-01-05  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	* builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.

	SYSTEM_ZLIB is used to switch the builtin zlib source
	or system zlib source out of FreeType2.  But ftbzip2
	module has no builtin bzip2 library and always requires
	system bzip2 library.  Thus SYSTEM_BZ2LIB is always yes,
	it is not used.

2011-01-03  Werner Lemberg  <wl@gnu.org>

	s/gzip_/comp_/.
	(PCF_Face_Init): Handle bzip2 compressed files.

	* docs/formats.txt, modules.cfg: Updated.

2010-12-25  Harsha  <mm.harsha@gmail.com>

	Apply Savannah patch #7422.

	If we encounter a space in a string then the sbit buffer is NULL,
	height and width are 0s.  So the check in ftc_snode_compare will
	always pass for spaces (comparision with 255).  Here the comments
	above the condition are proper but the implementation is not.  When
	we create an snode I think it is the proper way to initialize the
	width to 255 and then put a check for being equal to 255 in snode
	compare function.

	* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
	value 255.
	(ftc_snode_compare): Fix condition.

2010-12-13  Werner Lemberg  <wl@gnu.org>

2010-12-09  Werner Lemberg  <wl@gnu.org>

	[cff] Allow `hlineto' and `vlineto' without arguments.

	We simply ignore such instructions.  This is invalid, but it doesn't
	harm; and indeed, there exist such subsetted fonts in PDFs.

	Reported by Albert Astals Cid <aacid@kde.org>.

	* src/cff/cffgload.c (cff_decoder_parse_charstrings)
	[cff_op_hlineto]: Ignore instruction if there aren't any arguments
	on the stack.

2010-11-28  Werner Lemberg  <wl@gnu.org>

2010-11-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[truetype] Identify the tricky fonts by cvt/fpgm/prep checksums.
	Some Latin TrueType fonts are still expected to be unhinted.
	Fix Savannah bug #31645.

	* src/truetype/ttobjs.c (tt_check_trickyness): Divided to...

2010-11-04  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[UVS] Fix find_variant_selector_charmap(), Savannah bug #31545.

	Since 2010-07-04, find_variant_selector_charmap() returns
	the first cmap subtable always under rogue-compatible
	configuration, it causes NULL pointer dereference and
	make UVS-related functions crashed.

	* src/base/ftobjs.c (Fix find_variant_selector_charmap):
	Returns UVS cmap correctly.

2010-11-01  Alexei Podtelezhnikov  <apodtele@gmail.com>

	[ftsmooth] Improve rendering.

	* src/smooth/ftsmooth.c (gray_render_conic): Since version 2.4.3,
	cubic deviations have been estimated _after_ UPSCALE, whereas
	conic ones have been evaluated _before_ UPSCALE, which produces
	inferior rendering results.  Fix this.
	Partially undo change from 2010-10-15 by using ONE_PIXEL/4; this has
	been tested with demo images sent to the mailing list.  See

	  http://lists.gnu.org/archive/html/freetype-devel/2010-10/msg00055.html

	and later mails in this thread.

	[ftraster] Minor fixes.

	Reported by Tom Bishop <wenlin@wenlin.com>.

	* src/raster/ftraster.c (ULong): Remove unused typedef.
	(TWorker): Remove unused variable `precision_mask'.

2010-10-28  Werner Lemberg  <wl@gnu.org>

	[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.

	* 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.

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.

	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'.

	* src/base/ftobjs.c (FT_Done_Library): Specify the order of font
	drivers during the face closing process.  Type42 faces should be

	Fix for Savannah bug #30059.

	* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the
	minimum character code passed by a legacy rogue client by...
	* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
	This.  It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
	undefined (thus the rogue client compatibility is not required).

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.
