	[smooth] Slightly optimize conic and cubic flatterners.

	* src/smooth/ftgrays.c (gray_render_conic, gray_render_cubic): Move
	out some code from the main loop to speed it up.

2011-09-11  Tomas Hoger  <thoger@redhat.com>

	Slightly improve LZW_CLEAR handling.

	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
	Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
	handled as clear codes.  This also re-sets old_code and old_char to
	predictable values, which is a little better than using `random'
	ones if the code following LZW_CLEAR is invalid.

2011-09-11  Tomas Hoger  <thoger@redhat.com>

	Add explicit LZW decompression stack size limit.

	Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
	constructed correctly.  It's even less than that, see e.g. 
	libarchive code comment for a better size upper bound:

	  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121

	This patch adds explicit stack size limit, enforced when stack is
	realloced.

	An alternative is to ensure that code < state->prefix[code - 256]
	when traversing prefix table.  Such check is less efficient and
	should not be required if prefix table is constructed correctly in
	the first place.

	* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.

2011-09-11  Tomas Hoger  <thoger@redhat.com>

	Protect against loops in the prefix table.

	LZW decompressor did not sufficiently check codes read from the
	input LZW stream.  A specially-crafted or corrupted input could
	create a loop in the prefix table, which leads to memory usage
	spikes, as there's no decompression stack size limit.

	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
	code in valid LZW stream must be 0..255.
	<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
	code > free_ent is invalid.

2011-09-09  Werner Lemberg  <wl@gnu.org>

	[ftstroke] Major revision.

	The main problems
	-----------------

	  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
	    joins (not bevel joins) were generated.  Indeed, the meanings of
	    `miter' and `bevel' were incorrectly reversed (consistently) in
	    both the code and comments.

	  o The way bevel joins were constructed (whether specified
	    explicitly, or created as a result of exceeding the miter limit)
	    did not match what is required for stroked text in PostScript or
	    PDF.

	The main fixes
	--------------

	  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

	  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
	    introduced to support PostScript and PDF miter joins.

	  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
	    alias for FT_STROKER_LINEJOIN_MITER.

	Additionally, a variety of stroking errors have been fixed.  These
	would cause various artifacts (including points `at infinity'),
	especially when stroking poor quality fonts.

	See

	  http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html

	for example documents.  The FreeType stroker now produces results
	very similar to that produced by GhostScript and Distiller for these
	fonts.

	Other problems
	--------------

	The following problems have been resolved:

	  o Inside corners could be generated incorrectly.  Intersecting the
	    inside corner could cause a missing triangular area and other
	    effects.

	    The intersection point can only be used if the join is between
	    two lines and both lines are long enough.  The `optimization'
	    condition in `ft_stroker_inside' has been corrected; this
	    requires the line length to be passed into various functions and
	    stored in `FT_StrokerRec'.

	  o Incorrect cubic curves could be generated.  The angle
	    calculations in `FT_Stroker_CubicTo' have been corrected to
	    handle the case of the curve crossing the +/-PI direction.

	  o If the border radius was greater than the radius of curvature of
	    a curve, then the negative sector would end up outside (not
	    inside) the border.  This situation is now recognized and the
	    negative sector is circumnavigated in the opposite direction.
	    (If round line joins are being used, this code is disabled
	    because the line join will always cover the negative sector.)

	  o When a curve is split, the arcs may not join smoothly (especially
	    if the curve turns sharply back on itself).  Changes in
	    direction between adjacent arcs were not handled.  A round
	    corner is now added if the deviation from one arc to the next is
	    greater than a suitable threshold.

	  o The current direction wasn't retained if a the outline contained
	    a zero length lineto or a curve that was determined to be
	    `basically a point'.  This could cause a spurious join to be
	    added.

	  o Cubics with close control points could be mishandled.  All eight
	    cases are now distinguished correctly.

	Other improvements
	------------------

	o Borders for cubic curves could be too `flat'.
	  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
	  this.

	o The handling and use of movable points has been simplified a
	  little.

	o Various values are now computed only if the results are actually
	  needed.

	o The directions of the outer and inner borders have been swapped,
	  as recommended by Graham Asher.

	* include/freetype/ftstroke.h: Updated.

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

	[autofit] Add bluezones for CJK Ideographs.

	To remove extremas of vertical strokes of CJK Ideographs at
	low resolution and make the top and bottom horizontal stems
	aligned, bluezones for CJK Ideographs are calculated from
	sample glyphs.  At present, vertical bluezones (bluezones
	to align vertical stems) are disabled by default.  For detail, see

	(af_indic_hints_init): Ditto.
	(af_indic_hints_apply): Ditto.

2011-04-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[truetype] Always recalculate the sfnt table checksum.

	* src/truetype/ttobjs.c (tt_get_sfnt_checksum): Recalculate
	the sfnt table checksum even if non-zero value is written in
	the TrueType font header.  Some bad PDF generators write
	wrong values.  For details see examples and benchmark tests
	of the latency by recalculation:
	http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00091.html

2011-04-30  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[truetype] Register a set of tricky fonts, NEC FA family.

	* src/truetype/ttobjs.c (tt_check_trickyness_sfnt_ids):
	Add 8 checksum sets for NEC FA family.  For the tricky fonts
	without some tables (e.g. NEC FA fonts lack cvt table),
	extra check is added to assure that a zero-length table in the
	registry is not included in the font.

2011-04-29  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[truetype] Fix a bug in the sfnt table checksum getter.

	* src/truetype/ttobjs.c (tt_get_sfnt_checksum): Check the

	[autofit] Improve tracing messages.

	* src/autofit/aflatin.c (af_latin_metrics_init_blues,
	af_latin_align_linked_edge, af_latin_hint_edges): Do it.

2011-04-25  Kan-Ru Chen  <kanru@kanru.info>

	[truetype] Always check the checksum to identify tricky fonts.

	Because some PDF generators mangle the family name badly,
	the trickyness check by the checksum should be invoked always.
	For sample PDF, see
	http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00073.html

	* src/truetype/ttobjs.c (tt_check_trickyness): Even when
	tt_check_trickyness_family() finds no trickyness,
	tt_check_trickyness_sfnt_ids() is invoked.

2011-04-22  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

	[autofit] Add more Indic scripts with hanging baseline.

	* src/autofit/afindic.c (af_indic_uniranges): Tibetan, Limbu,
	Sundanese, Meetei Mayak, Syloti Nagri and Sharada scripts are
	added.

2011-04-21  Behdad Esfahbod  <behdad@behdad.org>

	Always ignore global advance.

	This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
	deprecated, and ignored.  The new behavior is what every major user
	of FreeType has been requesting.  Global advance is broken in many
	CJK fonts.  Just ignoring it by default makes most sense.

	* src/truetype/ttdriver.c (tt_get_advances),
	src/truetype/ttgload.c (TT_Get_HMetrics, TT_Get_VMetrics,
	tt_get_metrics, compute_glyph_metrics, TT_Load_Glyph),
	src/truetype/ttgload.h: Implement it.

	* docs/CHANGES: Updated.

2011-04-21  rainy6144  <rainy6144@gmail.com>

	[autofit] Blur CJK stems if too many to preserve their gaps.

	When there are too many stems to preserve their gaps in the
	rasterization of CJK Ideographs at a low resolution, blur the
	stems instead of showing clumped stems.  See
	http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html
	http://lists.gnu.org/archive/html/freetype-devel/2011-04/msg00046.html
	for details.

	* src/autofit/afcjk.c (af_cjk_hint_edges): Store the position of
	the previous stem by `has_last_stem' and `last_stem_pos', and skip
	a stem if the current and previous stem are too near to preserve
	the gap.

2011-04-18  Werner Lemberg  <wl@gnu.org>

	Integrate autofitter debugging stuff.

	* devel/ftoption.h, include/freetype/config/ftoption.h

	* src/psaux/psobjs.c (ps_table_add): Use FT_PtrDist for pointer
	difference.

2011-04-11  Kan-Ru Chen  <kanru@kanru.info>

	Fix reading of signed integers from files on 64bit platforms.

	Previously, signed integers were converted to unsigned integers, but
	this can fail because of sign extension.  For example, 0xa344a1eb
	becomes 0xffffffffa344a1eb.

	We now do the reverse which is always correct because the integer
	size is the same during the cast from unsigned to signed.

	* include/freetype/internal/ftstream.h, src/base/ftstream.c
	(FT_Stream_Get*): Replace with...
	(FT_Stream_GetU*): Functions which read unsigned integers.
	Update all macros accordingly.

	* src/gzip/ftgzip.c (ft_gzip_get_uncompressed_size): Updated.

2011-04-07  Werner Lemberg  <wl@gnu.org>

	* src/autofit/aftypes.h (AF_USE_WARPER): Remove.

	* src/autofit/*: s/AF_USE_WARPER/AF_CONFIG_OPTION_USE_WARPER/.

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.

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

	* src/autofit/afdummy.c: Include `aferrors.h'.
	Problem reported by Chris Liddell <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>

	Update classic MacOS makefiles 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/mac/FreeType.m68k_cfm.make.txt: Include ftbzip2.c.o.
	* builds/mac/FreeType.m68k_far.make.txt: Ditto.
	* builds/mac/FreeType.ppc_carbon.make.txt: Include ftbzip2.c.x.
	* builds/mac/FreeType.ppc_classic.make.txt: Ditto.

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

	Update Amiga makefiles 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/amiga/makefile: Include bzip2.ppc.o built from ftbzip2.c.
	* builds/amiga/makefile.os4: Include bzip2.o built from ftbzip2.c.
	* builds/amiga/smakefile: Ditto.

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>

	*/rules.mk: Handle `*pic.c' files.

2010-12-31  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>

	Fix parameter handling of `FT_Set_Renderer'.

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>

	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

	* 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.

	[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.

	`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

	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/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto.
	* src/cff/cffload.c (cff_encoding_load): Remove conditional check
	which always evaluates to `true'.

	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

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.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?',

	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
	be loaded for the interpreter.  Reported by Robert Święcki.

	Initial fix for Savannah bug #30306.

	* src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the

	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.
