54	* include/freetype/config/ftconfig.h [FT_LONG64]: Typedef
55	`FT_Int64' here.

62
63	[raster] Fix clang issues.
64
65	Fix suggested by <octoploid@yandex.com>.
66
67	* src/raster/ftraster.c (ULong): New typedef.

71
72	Fix clang fixes.
73
74	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate): Use
75	correct types.
76
77	* src/cff/cf2intrp.c (cf2_interpT2CharString) <default>: Force
78	unsigned for computations.
79	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Ditto.

83
842013-05-04  Werner Lemberg  <wl@gnu.org>
85
86	[cff] Make Adobe CFF engine work correctly on 64bit hosts.
87
88	Reported by numerous people on the `freetype-devel' list.  Without
89	this fix, glyphs aren't properly aligned on a common baseline.
90
91	On 64bit systems, `FT_Pos' expands to `long int', having a width of
92	64bit.  `CF2_Fixed' expands to `int' which is normally 32bit wide on
93	64bit hosts also.  Wrong casts filled up the blues arrays with
94	incorrect values.  Note that all blues values are accessed with the
95	`cf2_blueToFixed' macro which handles the 64bit to 32bit conversion.
96
97	* src/cff/cf2ft.h (cf2_getBlueValues, cf2_getOtherBlues,
98	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Use `FT_Pos' for
99	`data', not `CF2_Fixed'.
100	* src/cff/cf2ft.c (cf2_getBlueValues, cf2_getOtherBlues,
101	cf2_getFamilyBlues, cf2_getFamilyOtherBlues): Updated.
102	* src/cff/cf2blues.c (cf2_blues_init): Updated.
103
1042013-05-04  Werner Lemberg  <wl@gnu.org>
105
106	More fixes for clang's `sanitize' feature.
107
108	* src/base/ftcalc.c (FT_DivFix): Use unsigned values for
109	computations which use the left shift operator and convert to signed
110	as the last step.
111	* src/base/fttrigon.c (ft_trig_prenorm, FT_Vector_Rotate,
112	FT_Vector_Length, FT_Vector_Polarize): Ditto.
113
114	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Simplify.
115	* src/cff/cffload.c (cff_subfont_load): Fix constant.
116	* src/cff/cffparse.c (cff_parse_integer, cff_parse_real, do_fixed,
117	cff_parse_fixed_dynamic): Use unsigned values for computations which
118	use the left shift operator and convert to signed as the last step.
119
120	* src/cid/cidload.c (cid_get_offset): Ditto.
121
122	* src/psaux/psconv.c (PS_Conv_ToFixed): Ditto.
123	* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Ditto.
124
125	* src/truetype/ttinterp.c (TT_MulFix14, TT_DotFix14): Ditto.
126
1272013-05-04  Werner Lemberg  <wl@gnu.org>
128
129	Fix errors reported by clang's `sanitize' feature.
130
131	* include/freetype/internal/ftstream.h: Simplify and fix integer
132	extraction macros.
133	(FT_INT8_, FT_BYTE_I16, FT_BYTE_I32, FT_INT8_I16, FT_INT8_I32,
134	FT_INT8_I32, FT_INT8_U32): Removed.
135	(FT_PEEK_SHORT, FT_PEEK_LONG, FT_PEEK_OFF3, FT_PEEK_SHORT_LE,
136	FT_PEEK_LONG_LE, FT_PEEK_OFF3_LE): Use unsigned values for
137	computations and convert to signed as the last step.
138
139	* src/cff/cf2fixed.h (cf2_intToFixed, cf2_fixedToInt,
140	cf2_fracToFixed): Avoid shifts of negative values.
141	(cf2_intToFrac, cf2_fixedToFrac, cf2_fixedTo26Dot6): Removed,
142	unused.
143
144	* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdEXTENDEDNMBR,
145	default>: Use unsigned values for computations and convert to signed
146	as the last step.
147	Use proper types in tracing messages.
148
149	* src/cff/cffgload.c (cff_decoder_parse_charstrings): Use unsigned
150	values for computation of operands and convert to signed as the last
151	step.
152	Use proper type in tracing message.
153
1542013-05-03  Werner Lemberg  <wl@gnu.org>

168
169	[cff] Add a new Type 2 interpreter and hinter.
170
171	This work, written by Dave Arnold <darnold@adobe.com> and fully
172	integrated into FreeType by me, is a donation by Adobe in
173	collaboration with Google.  It is vastly superior to the old CFF
174	engine, and it will replace it soon.  Right now, it is still off by
175	default, and you have to explicitly select it using the new
176	`hinting-engine' property of the cff driver.
177
178	For convenience, (most of) the new files are committed separately.
179
180	* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
181	* include/freetype/ftcffdrv.h: New file to access CFF driver
182	properties.
183	* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
184	code.
185	* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
186	and `cf2interp'.
187
188	* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
189	* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
190	and `no_stem_darkening'.
191	* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.
192
193	* src/cff/cff.c: Include new files.
194	* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
195	`hinting-engine' and `no-stem-darkening' properties (only the Adobe
196	engine listens to them).
197	* src/cff/cffgload.c: Include `cf2ft.h'.
198	(cff_decoder_prepare): Initialize `current_subfont'.
199	(cff_build_add_point): Handle Adobe engine which uses 16.16
200	coordinates.
201	(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
202	separately.
203	Choose rendering engine based on `hinting_engine' property.
204	* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
205	engine.
206	* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
207	(cff_driver_init): Set default property values.
208
209	* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.
210
211	* src/cff/cf2*.*: New files, containing the Adobe engine.
212
2132013-04-12  Werner Lemberg  <wl@gnu.org>
214
215	[cff] Minor code administration issues.
216
217	* src/cff/cffgload.c (check_points): Rename to...
218	(cff_check_points): ...this and make it FT_LOCAL.
219	(cff_builder_add_point, cff_builder_add_point1,
220	cff_builder_start_point, cff_builder_close_contour,
221	cff_lookup_glyph_by_stdcharcode, cff_get_glyph_data,
222	cff_free_glyph_data): Make them FT_LOCAL.
223
224	* src/cff/cffgload.h: Updated.
225
2262013-04-12  Werner Lemberg  <wl@gnu.org>
227
228	Add output bitmap checksums.
229
230	Use `FT2_DEBUG=bitmap:3' for tracing.
231
232	* src/base/md5.c, src/base/md5.h: New files, taken from
233
234	  http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5

236	* include/freetype/internal/fttrace.h: Add `bitmap'.
237
238	* src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'
239
240	(FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,
241	convert resulting bitmap to a uniform format and compute a checksum.
242	Use `bitmap' category for the tracing message.
243
244	* src/base/rules.mk (BASE_H): Updated.
245
246	* docs/LICENSE.TXT: Updated.
247
2482013-04-12  Werner Lemberg  <wl@gnu.org>
249
250	[cff] Add framework for CFF properties.
251
252	* include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC7):
253	New macro.
254
255	* src/cff/cffdrivr.c: Include FT_SERVICE_PROPERTIES_H.
256	(cff_property_set, cff_property_get): New functions, still empty.
257	Define `cff_service_properties' service.
258	Update `cff_services'.
259
260	* src/cff/cffpic.h: Include FT_SERVICE_PROPERTIES_H.
261	(CFF_SERVICE_PROPERTIES_GET): New macro.
262	(CffModulePIC): Add `cff_service_properties'.
263
2642013-04-03  Werner Lemberg  <wl@gnu.org>
265
266	[bdf] Fix Savannah bug #38589.
267
268	* src/bdf/bdflib.c (_bdf_readstream): Thinko.
269
2702013-03-31  Werner Lemberg  <wl@gnu.org>
271
272	* configure: Use egrep, not grep.
273
274	Problem reported Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
275
2762013-03-29  Werner Lemberg  <wl@gnu.org>
277
278	* include/freetype/ftlcdfil.h: Add description of color filtering.
279
280	Based on a contribution from Antti S. Lankila <alankila@bel.fi>
281	(Savannah bug #38607).
282
2832013-03-23  Werner Lemberg  <wl@gnu.org>
284
285	[autofit] Minor.
286
287	* src/autofit/afmodule.c (af_property_set): Typo.
288	(af_autofitter_init, af_autofitter_done): Use cast.
289
2902013-03-21  Werner Lemberg  <wl@gnu.org>
291
292	* configure: Automatically test for `gmake' also.
293
294	Suggested by Mojca Miklavec <mojca.miklavec.lists@gmail.com>.
295
2962013-03-21  Peter Breitenlohner  <peb@mppmu.mpg.de>
297
298	Respect CONFIG_SHELL from the environment.
299
300	Some large packages using FreeType have to use a broken (deficient)
301	/bin/sh.  The configure scripts (as generated by Autoconf) are
302	clever enough to find a better shell and put that one into the
303	environment variable CONFIG_SHELL.  If that environment variable is
304	already set the script skips the test and assumes to be already
305	running under a good shell.
306
307	* builds/unix/detect.mk: Honour CONFIG_SHELL.
308	* builds/unix/unix-def.in (SHELL): Define.
309
3102013-03-21  Werner Lemberg  <wl@gnu.org>
311
312	Fix Savannah patch #7971.
313
314	* configure: Handle MAKE environment variable also.
315
3162013-03-17  Werner Lemberg  <wl@gnu.org>
317
318	Fix Savannah bug #38538.
319
320	* builds/amiga/src/base/ftdebug.c, builds/win32/ftdebug.c,
321	builds/wince/ftdebug.c (FT_Throw): Add function.
322
3232013-03-17  Werner Lemberg  <wl@gnu.org>
324
325	[raster] Remove dead code.
326
327	* src/raster/rastpic.c (ft_raster1_renderer_class_pic_init)
328	src/smooth/ftspic.c (ft_smooth_renderer_class_pic_init): Do it.
329
3302013-03-17  Werner Lemberg  <wl@gnu.org>
331
332	* src/pshinter/pshpic.h (GET_PIC): Use correct container.
333
3342013-03-15  Werner Lemberg  <wl@gnu.org>
335
336	* include/freetype/ftmoderr.h: Fix commit from 2013-03-11.
337
338	The previous version was not backwards compatible.  Reported by
339	Behdad.
340
3412013-03-14  Werner Lemberg  <wl@gnu.org>
342
343	*/*: Use FT_ERR_EQ, FT_ERR_NEQ, and FT_ERR where appropriate.
344
345	FT_Err_XXX and friends are no longer directly used in the source
346	code.
347
3482013-03-14  Werner Lemberg  <wl@gnu.org>
349
350	New error management macros.
351
352	* include/freetype/fterrors.h (FT_ERR_XCAT, FT_ERR_CAT): Move to...
353	* include/freetype/fttypes.h: ... this file.
354	(FT_ERR, FT_ERR_EQ, FT_ERR_NEQ, FT_MODERR_EQ, FT_MODERR_NEQ): New
355	macros.
356
357	* include/freetype/freetype.h: Updated.
358
3592013-03-14  Werner Lemberg  <wl@gnu.org>
360
361	*/*: Use FT_Err_Ok only.
362
363	This is a purely mechanical conversion.
364
3652013-03-14  Werner Lemberg  <wl@gnu.org>
366
367	*/*: Use `FT_THROW'.
368
369	This is essentially a mechanical conversion, adding inclusion of
370	`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
371	stand-alone compiling modes of the rasterizer modules.
372
373	To convert the remaining occurrences of FT_Err_XXX and friends it is
374	necessary to rewrite the code.  Note, however, that it doesn't harm
375	if some cases are not handled since FT_THROW is a no-op.
376
3772013-03-13  Werner Lemberg  <wl@gnu.org>
378
379	Introduce `FT_THROW' macro.
380
381	The idea is to replace code like
382
383	  return FT_Err_Foo_Bar;
384
385	or
386
387	  return CFF_Err_Foo_Bar;
388
389	with
390
391	  return FT_THROW( Foo_Bar );
392
393	The FT_THROW macro has two functions:
394
395	  . It hides the module specific prefix.
396
397	  . In debug mode, it calls the empty function `FT_Throw' which can
398	    be thus used to set a breakpoint.
399
400	* include/freetype/internal/ftdebug.h (FT_THROW): New macro.
401	(FT_Throw): New prototype.
402	* src/base/ftdebug.c (FT_Throw): New function.
403
4042013-03-12  Werner Lemberg  <wl@gnu.org>
405
406	Remove `FT_KEEP_ERR_PREFIX'.
407
408	The idea is to always have FT_ERR_PREFIX available internally.
409
410	* include/freetype/fterrors.h: Use FT2_BUILD_LIBRARY to guard
411	undefinition of FT_ERR_PREFIX
412
413	* src/gxvalid/gxverror.h, src/otvalid/otverror.h,
414	src/sfnt/sferrors.h: Updated.
415
4162013-03-11  Werner Lemberg  <wl@gnu.org>
417
418	[gxvalid] Fix module error.
419
420	* src/gxvalid/gxverror.h (FT_ERR_BASE): Define as
421	FT_Mod_Err_GXvalid.
422	* include/freetype/ftmoderr.h: Add module error for `GXvalid'.
423
4242013-03-11  Werner Lemberg  <wl@gnu.org>
425
426	Always use module related error codes.
427
428	* src/cff/cffobjs.c (cff_face_init), src/type1/t1objs.c
429	(T1_Face_Init), src/type42/t42objs.c (T42_Face_Init): Use
430	`FT_ERROR_BASE'.
431
432	* src/type1/t1load.c (parse_encoding): Use
433	T1_Err_Unknown_File_Format.
434
4352013-03-08  Werner Lemberg  <wl@gnu.org>
436
437	[cff] Set `linear{Hori,Vert}Advance' for embedded bitmaps also.
438
439	Problem reported by Khaled Hosny <khaledhosny@eglug.org>.
440
441	* src/cff/cffgload.c (cff_slot_load): Implement it.
442
4432013-02-23  Alexei Podtelezhnikov  <apodtele@gmail.com>
444
445	[base] Fix commit ab02d9e8.
446
447	* src/base/ftbbox.c (BBox_Cubic_Check): Change scaling to msb of 22.
448
4492013-02-19  Alexei Podtelezhnikov  <apodtele@gmail.com>
450
451	[base] New bisecting BBox_Cubic_Check (disabled).
452
453	* src/base/ftbbox.c (BBox_Cubic_Check): New bisecting algorithm
454	for extremum search built around simple condition that defines
455	which half contains the extremum.
456
4572013-02-18  Alexei Podtelezhnikov  <apodtele@gmail.com>
458
459	[tools] Update BBox testing tool.
460
461	* src/tools/test_bbox.c: Add another cubic outline with exact BBox.
462	(REPEAT): Increase the number of benchmarking cycles.
463	(profile_outline): Tweak output formatting.
464
4652013-02-02  Werner Lemberg  <wl@gnu.org>
466
467	Fix Savannah bug #38235.
468
469	* builds/unix/configure.raw: Don't generate `freetype-config' and
470	`freetype.pc'.
471
472	* builds/unix/unix-def.in (FT2_EXTRA_LIBS, LIBBZ2, LIBZ,
473	build_libtool_libs, ft_version): New variables to be substituted.
474	(freetype-config, freetype.pc): New rules to generate those files.
475
476	* builds/unix/freetype-config.in: Remove code for handling `rpath'.
477	The use of $rpath has been accidentally removed in a patch from
478	2009-12-22, and apparently noone has missed it since.
479	Use `%' instead of `@' as a variable substitution marker.
480	Use quotes.
481
482	* builds/unix/freetype.in: Use `%' instead of `@' as a variable
483	substitution marker.

487
488	* src/truetype/ttobjs.c (tt_size_run_prep): Reset more GS variables.
489
490	BTW, Greg agrees that the OpenType specification is missing the list
491	of GS variables which will always be reset to the default values
492	after the `prep' table has been executed.
493
4942013-02-06  Werner Lemberg  <wl@gnu.org>
495
496	* src/truetype/ttobjs.c (tt_size_run_prep): Reset reference points.
497
498	Up to now, we simply took a snapshot of the Graphics State after the
499	`prep' table has been executed, and right before a glyph's bytecode
500	was run it got reloaded.  However, as Greg Hitchcock has told us in
501	private communication, reference points get reset to zero in the MS
502	rasterizer and we follow in due course.  While reasonable, this is
503	undocumented behaviour.
504
505	Most notably, this fixes the rendering of Arial's `x' glyph in
506	subpixel hinting mode.

645
646	Also avoid possible integer overflow issues, for example, using

746
747	[truetype] Improve sub-pixel code.
748
749	This patches fixes many issues with the ttsubpix implementation.
750
751	1. Data tables are defined, instead of declared, in the header, and
752	   thus copied into each source file that includes it.
753
754	2. These tables were defined as global, mutable, visible variables,
755	   and thus costing private RAM to every process that loads the
756	   library (> 50 KB / process, this is huge!).
757
758	   Additionally, this also made the library export the symbols
759	   completely needlessly.
760
761	3. Missing `sph_' and `SPH_' prefixes to some of the definitions.
762
763	Note that this doesn't try to fix the incredibly inefficient storage
764	format for the data tables used by the code.  This one will require
765	another pass in the future.
766
767	* src/truetype/ttinterp.h (MAX_NAME_SIZE, MAX_CLASS_MEMBERS):

792	[truetype] Improve accuracy of normalization of short vectors.
793
794	Unit vector components are stored as 2.14 fixed-point numbers. In
795	order to calculate all 14 bits accurately, a short vector to be
796	normalized has to be upscaled to at least 14 bits before its length
797	is calculated. This has been safe since accurate CORDIC algorithms
798	were adopted.

803
804	[truetype] Kill very old vector normalization hacks.
805
806	Back in the days, vector length calculations were not very accurate
807	and the vector normalization function, Normalize, had to meticulously
808	correct the errors for long vectors [commit b7ef2b096867]. It was no
809	longer necessary after accurate CORDIC algorithms were adopted, but
810	the code remained. It is time to kill it.

958	that once the vector is in the right half-plane, the initial rotation
959	by 63 degrees is not necessary. The algorithm is perfectly capable
960	to converge to any angle starting from the second 45 degree rotation.

1085
1086	[truetype] Scale F_dot_P down.
1087
1088	The dot product between freeVector and projVector or cosine of
1089	the angle between these FT_F2Dot14 unit vectors used to be scaled up
1090	by 4 and routinely occupied 32 bits in an FT_Long field F_dot_P.
1091	This patch scales the value down by 2^14 instead, which simplifies
1092	its use throughout the bytecode interpreter.
1093
1094	This does not lead to the loss of precision because the lower bits
1095	are unreliable anyway. Consider two unit vectors (1,0) and (.6,.8)
1096	for which the true value of F_dot_P is .6 * 0x40000000 = 0x26666666.
1097	These vectors are stored as (0x4000,0) and (0x2666,0x3333) after
1098	rounding and F_dot_P is assigned 0x26660000. The lower bits were
1099	already lost while rounding the unit vector components.
1100
1101	Besides code simplification, this change can lead to better
1102	performance when FT_MulDiv with the scaled-down F_dot_P is less
1103	likely to use the costly 64-bit path. We are not changing the type
1104	of F_dot_P to FT_F2Dot14 at this point.
1105
1106	* src/truetype/ttinterp.c (Compute_Funcs): Scale F_dot_P down by 14
1107	bits and modify its use accordingly.
1108	(Direct_Move, Direct_Move_Orig, Compute_Point_Displacement): Modify
1109	the use of F_dot_P field.
1110	* src/truetype/ttobjs.c (tt_size_run_fpgm): Change arbitrary
1111	assignment of F_dot_P to its theoretical maximum in case we decide
1112	to scale back its type later.

1425	[autofit] Implement Infinality's `increase glyph heights'.
1426
1427	This is an improved version of a similar fix contained in the
1428	so-called `Infinality patch', taken from
1429
1430	  http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2

1432	which addresses various enhancements of the auto-hinter.  Without
1433	properties to control a module's metadata it wasn't possible to

1860	Fix `checking if gcc static flag -static works' test.
1861
1862	On my linux build tree, I receive yes answer in in every package I
1863	build except freetype for this test checking if gcc static flag
1864	`-static' works
1865
1866	On freetype, no is received, unless bzip2 and zlib are disabled using
1867
1868	  ./configure --without-bzip2 --without-zlib
1869
1870	The reason is that bzip2 and zlib tests add `-lz' and `-lbz2' to
1871	LDFLAGS and this broke static flag test.
1872
1873	* builds/unix/configure.raw: Update CFLAGS and LDFLAGS only after
1874	LT_INIT has run.

1933	[truetype] Remove unused rounding functionality.
1934
1935	The subpixel hinting patch contained the concept of an adjustable
1936	number of gridlines per pixel.  This is no longer used due to x

19672012-06-18  Infinality  <infinality@infinality.net>
1968
1969	[truetype] Support subpixel hinting.
1970
1971	This is the large, famous `Infinality' patch to support ClearType
1972	bytecode which has been available from
1973	http://www.infinality.net/blog/ for some time, and which has been
1974	refined over the last years.  While still experimental, it is now
1975	mature enough to be included directly into FreeType.
1976
1977	Most of the code is based on the ClearType whitepaper written by
1978	Greg Hitchcock
1979
1980	  http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
1981
1982	which gives a detailed overview of the necessary changes to the
1983	Microsoft rasterizer so that older fonts are supported.  However, a
1984	lot of details are still missing, and this patches provides a
1985	framework to easily handle rendering issues down to the glyph level
1986	of certain fonts.
1987
1988	Note that ClearType support is not completely implemented!  In
1989	particular, full support for the options `compatible_widths',
1990	`symmetrical_smoothing, and `bgr' (via the GETINFO bytecode
1991	instruction) is missing.
1992
1993	* src/truetype/ttsubpix.c: New file, providing code to handle
1994	`tweaks', this is, rules for certain glyphs in certain fonts
1995	(including wildcards) which need a special treatment.
1996

2242	[autofit] Return correct linear advance width values.
2243
2244	This was quite a subtle bug which accidentally showed up with glyph
2245	`afii10023' of arial.ttf (version 2.76).  This glyph is a composite;
2246	the first component, `E', has an advance width of 1366 font units,
2247	while the advance width of the composite itself (which looks like
2248	uppercase `E' with dieresis) is 1367 font units.  I think this is
2249	actually a bug in the font itself, because there is no reason that
2250	this glyph has not the same width as uppercase `E' without the
2251	dieresis.  Anyway, it helped identify this problem.
2252
2253	Using the TrueType hinter, the correct value (1367) of `afii10023'
2254	was returned, but the autohinter mysteriously returned 1366.
2255
2256	Digging in the code showed that the autohinter recursively calls
2257	FT_Load_Glyph to load the glyph, adding the FT_LOAD_NO_SCALE load
2258	flag.  However, the `linearHoriAdvance' field is still returned as a
2259	scaled value.  To avoid scaling twice, the old code in autofit reset
2260	`linearHoriAdvance', using the `horiAdvance' field.  This seemed to
2261	work since FT_LOAD_NO_SCALE was in use, but it failed actually,
2262	because `horiAdvance' is defined as the distance of the first
2263	subglyph's phantom points, which in turn are initialized using the
2264	advance width of the first subglyph.  And as the given example
2265	shows, these widths can differ.
2266
2267	* src/autofit/afloader.c (af_loader_load_g): Temporarily set
2268	FT_LOAD_LINEAR_DESIGN while calling FT_Load_Glyph to get unscaled
2269	values for the linear advance widths.

2351
2352	* src/psaux/afmparse.c (afm_parse_track_kern): Don't inverse sign

2413
2414	* src/bdf/bdflib.c (_bdf_parse_glyphs) <DWIDTH, BBX>: Abort if

2733	[autofit] Fix the inclusion of `aflatin2.h' in PIC file.
2734
2735	* src/autofit/afpic.c: Include `aflatin2.h' when
2736	FT_OPTION_AUTOFIT2 is defined, as afglobal.c does so.
2737	Unconditionally inclusion causes declared but unimplemented
2738	warning by GCC 4.6.

2741
2742	[cff] Remove redundant declarations of cff_cmap_XXX_class_rec.
2743
2744	* src/cff/cffpic.c: The declarations of
2745	FT_Init_Class_cff_cmap_encoding_class_rec() and
2746	FT_Init_Class_cff_cmap_unicode_class_rec() are removed.
2747	They can be obtained by the inclusion of cffcmap.h.
2748	cffcmap.h invokes FT_DECLARE_CMAP_CLASS() and it declares
2749	FT_Init_Class_cff_cmap_encoding_class_rec() etc in PIC mode.
2750
27512012-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
2752
2753	Fix redundant declaration warning in PIC mode.
2754
2755	Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
2756	designed to declare xxx_pic_{free,init} by themselves.
2757	Because these macros are used at the end of the module
2758	interface (e.g. ttdriver.c) and the wrapper source to build
2759	a module as a single object (e.g. truetype.c) includes
2760	the PIC file (e.g. ttpic.c) before the module interface,
2761	these macros are expanded AFTER xxx_pic_{free,init} body
2762	when the modules are built as single object.
2763	The declaration after the implementation causes the redundant
2764	declaration warnings, so the declarations are moved to module
2765	PIC headers (e.g. ttpic.h).  Separating to other header files
2766	are needed for multi build.
2767
2768	* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
2769	Remove class_##_pic_free and class_##_pic_init declarations.
2770	* include/freetype/internal/ftobjs.h (FT_DEFINE_RENDERER,
2771	FT_DEFINE_MODULE): Ditto.

2777	* src/pshinter/pshpic.h: Declare pshinter_module_class_pic_{free,
2778	init}.
2779	* src/psnames/pspic.h: Declare psnames_module_class_pic_{free,
2780	init}.
2781	* src/raster/rastpic.h: Declare

2796	[base] Fix a dereference of uninitialized variable in PIC mode.
2797
2798	* src/base/ftglyph.c (FT_Glyph_To_Bitmap): `glyph' must be
2799	set before derefering to obtain `library'.  The initialization
2800	of `clazz', `glyph', `library' and NULL pointer check are
2801	reordered to minimize PIC conditonals.
2802
28032012-01-14  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
2804
2805	[base] Insert explicit cast for GCC 4.6 in PIC mode.
2806
2807	* src/base/ftinit.c (FT_Add_Default_Modules): Under PIC
2808	configuration, FT_DEFAULT_MODULES_GET returns
2809	FT_Module_Class** pointer, GCC 4.6 warns that
2810	const FT_Module_Class* const* variable is warned as
2811	inappropriate to store it.  To calm it, explicit cast is
2812	inserted.  Also `library' is checked to prevent the NULL
2813	pointer dereference in FT_DEFAULT_MODULES_GET.
2814

2820	take no arguments but derefer the variable named `library'
2821	internally.
2822
2823	* src/cff/cffdrivr.c (cff_get_interface): Declare `library' and
2824	set it if non-NULL driver is passed.

2857
28582011-12-10  Werner Lemberg  <wl@gnu.org>
2859
2860	Add some variable initializations.
2861	Reported by Richard COOK <rscook@unicode.org>.
2862
2863	* src/type1/t1driver.c (t1_ps_get_font_value): Initialize `val'.
2864	* src/smooth/ftgrays.c (gray_render_conic): Initialize `levels'
2865	earlier.
2866
28672011-12-08  Werner Lemberg  <wl@gnu.org>
2868
2869	Fix serious scaling bug in `FT_Get_Advances'.
2870
2871	* src/base/ftadvanc.c (FT_Get_Advances): Advance values returned by
2872	`FT_Load_Glyph' must be simply multiplied by 1024.
2873
28742011-12-08  Werner Lemberg  <wl@gnu.org>

2879
2880	[mac] Unify DARWIN_NO_CARBON with FT_MACINTOSH.
2881
2882	Originally FT_MACINTOSH was a pure auto macro and DARWIN_NO_CARBON
2883	was a configurable macro to disable Carbon-dependent code.  Because
2884	now configure script sets DARWIN_NO_CARBON by default and disables
2885	Darwin & Carbon-dependent codes, these macros can be unified.
2886	FT_MACINTOSH (undefined by default) is kept and DARWIN_NO_CARBON
2887	(defined by default) is removed, because DARWIN_NO_CARBON violates
2888	FT_XXX naming convention of public macros, and a macro configured by
2889	default is not portable for the building without configure (e.g.
2890	make devel).
2891
2892	* builds/unix/configure.raw: Define FT_MACINTOSH if Carbon-based
2893	old Mac font support is requested and Carbon is available.
2894	* builds/unix/ftconfig.in: Undefine FT_MACINTOSH when the support
2895	for Mac OS X without Carbon (e.g.  Mac OS X 10.4 for ppc64) is
2896	requested.
2897	* include/freetype/config/ftconfig.in: Ditto.
2898	* builds/vms/ftconfig.h: Ditto.
2899
2900	* src/base/ftbase.h: Remove DARWIN_NO_CARBON.

2924	[apinames] Fix the overflow of signed integer hash.
2925
2926	* src/tools/apinames.c (names_add): Change the type of `h' from
2927	int to unsigned int, to prevent undefined behaviour in the
2928	overflow of signed integers (overflow of unsigned int is defined
2929	to be wrap around).  Found by clang test suggested by Sean

2959	src/type1/t1objs.h (T1_Driver): Remove unused typedef.
2960	Updated for t1driver changes.
2961
29622011-11-27  Werner Lemberg  <wl@gnu.org>
2963
2964	[bdf] Fix Savannah bug #34896.
2965
2966	ENCODING now covers the whole Unicode range.
2967
2968	Note, however, that this change is quite expensive since it
2969	increases the size of three arrays by almost 400kByte in total.  The
2970	right fix is to replace the logic with something smarter.
2971	Additionally, there exist very old BDFs for three-byte CCCII
2972	encoding which exceeds the range of Unicode (another reason to have
2973	a smarter logic).
2974
2975	* src/bdf/bdf.h (bdf_font_t): Increase size of `nmod' and `umod'

3268
32692011-09-11  Tomas Hoger  <thoger@redhat.com>
3270
3271	Slightly improve LZW_CLEAR handling.
3272
3273	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
3274	Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
3275	handled as clear codes.  This also re-sets old_code and old_char to
3276	predictable values, which is a little better than using `random'
3277	ones if the code following LZW_CLEAR is invalid.
3278
32792011-09-11  Tomas Hoger  <thoger@redhat.com>
3280
3281	Add explicit LZW decompression stack size limit.
3282
3283	Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
3284	constructed correctly.  It's even less than that, see e.g.
3285	libarchive code comment for a better size upper bound:
3286
3287	  http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
3288
3289	This patch adds explicit stack size limit, enforced when stack is
3290	realloced.
3291
3292	An alternative is to ensure that code < state->prefix[code - 256]
3293	when traversing prefix table.  Such check is less efficient and
3294	should not be required if prefix table is constructed correctly in
3295	the first place.
3296
3297	* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
3298
32992011-09-11  Tomas Hoger  <thoger@redhat.com>
3300
3301	Protect against loops in the prefix table.
3302
3303	LZW decompressor did not sufficiently check codes read from the
3304	input LZW stream.  A specially-crafted or corrupted input could
3305	create a loop in the prefix table, which leads to memory usage
3306	spikes, as there's no decompression stack size limit.
3307
3308	* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
3309	code in valid LZW stream must be 0..255.
3310	<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
3311	code > free_ent is invalid.

3527	[ftstroke] Major revision.
3528
3529	The main problems
3530	-----------------
3531
3532	  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
3533	    joins (not bevel joins) were generated.  Indeed, the meanings of
3534	    `miter' and `bevel' were incorrectly reversed (consistently) in
3535	    both the code and comments.
3536
3537	  o The way bevel joins were constructed (whether specified
3538	    explicitly, or created as a result of exceeding the miter limit)
3539	    did not match what is required for stroked text in PostScript or
3540	    PDF.
3541
3542	The main fixes
3543	--------------
3544
3545	  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.
3546
3547	  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
3548	    introduced to support PostScript and PDF miter joins.
3549
3550	  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
3551	    alias for FT_STROKER_LINEJOIN_MITER.
3552
3553	Additionally, a variety of stroking errors have been fixed.  These
3554	would cause various artifacts (including points `at infinity'),
3555	especially when stroking poor quality fonts.
3556
3557	See
3558
3559	  http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html
3560
3561	for example documents.  The FreeType stroker now produces results
3562	very similar to that produced by GhostScript and Distiller for these
3563	fonts.
3564
3565	Other problems
3566	--------------
3567
3568	The following problems have been resolved:
3569
3570	  o Inside corners could be generated incorrectly.  Intersecting the
3571	    inside corner could cause a missing triangular area and other
3572	    effects.
3573
3574	    The intersection point can only be used if the join is between
3575	    two lines and both lines are long enough.  The `optimization'
3576	    condition in `ft_stroker_inside' has been corrected; this
3577	    requires the line length to be passed into various functions and
3578	    stored in `FT_StrokerRec'.
3579
3580	  o Incorrect cubic curves could be generated.  The angle
3581	    calculations in `FT_Stroker_CubicTo' have been corrected to
3582	    handle the case of the curve crossing the +/-PI direction.
3583
3584	  o If the border radius was greater than the radius of curvature of
3585	    a curve, then the negative sector would end up outside (not
3586	    inside) the border.  This situation is now recognized and the
3587	    negative sector is circumnavigated in the opposite direction.
3588	    (If round line joins are being used, this code is disabled
3589	    because the line join will always cover the negative sector.)
3590
3591	  o When a curve is split, the arcs may not join smoothly (especially
3592	    if the curve turns sharply back on itself).  Changes in
3593	    direction between adjacent arcs were not handled.  A round
3594	    corner is now added if the deviation from one arc to the next is
3595	    greater than a suitable threshold.
3596
3597	  o The current direction wasn't retained if a the outline contained
3598	    a zero length lineto or a curve that was determined to be
3599	    `basically a point'.  This could cause a spurious join to be
3600	    added.
3601
3602	  o Cubics with close control points could be mishandled.  All eight
3603	    cases are now distinguished correctly.
3604
3605	Other improvements
3606	------------------
3607
3608	o Borders for cubic curves could be too `flat'.
3609	  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
3610	  this.
3611
3612	o The handling and use of movable points has been simplified a
3613	  little.
3614
3615	o Various values are now computed only if the results are actually
3616	  needed.
3617
3618	o The directions of the outer and inner borders have been swapped,
3619	  as recommended by Graham Asher.

3753	  if ( valid->root->level >= FT_VALIDATE_PARANOID )
3754	    FT_INVALID_xxx;
3755
3756	To simplify them, GXV_SET_ERR_IF_PARANOID( err ) is
3757	introduced for more paranoid validation in future.
3758

4107	[truetype] Always check the checksum to identify tricky fonts.

4144	[autofit] Blur CJK stems if too many to preserve their gaps.
4145
4146	When there are too many stems to preserve their gaps in the
4147	rasterization of CJK Ideographs at a low resolution, blur the
4148	stems instead of showing clumped stems.  See
4149	http://lists.gnu.org/archive/html/freetype-devel/2011-02/msg00011.html

41912011-04-11  Kan-Ru Chen  <kanru@kanru.info>
4192
4193	Fix reading of signed integers from files on 64bit platforms.
4194
4195	Previously, signed integers were converted to unsigned integers, but
4196	this can fail because of sign extension.  For example, 0xa344a1eb
4197	becomes 0xffffffffa344a1eb.
4198
4199	We now do the reverse which is always correct because the integer
4200	size is the same during the cast from unsigned to signed.

4461	Old GNU binutils could not accept the reduced syntax
4462	`orr %0, %2, lsl #16'.  Un-omitted syntax like RVCT,
4463	`orr %0, %0, %2, lsl #16' is better.  Reported by
4464	Johnson Y. Yan.  The bug report by Qt developers is
4465	considered too.

4471	[raster] Make bbox handling the same as with Microsoft's rasterizer.
4472
4473	Right before B/W rasterizing, the bbox gets simply rounded to
4474	integers.  This fixes, for example, glyph `three' in font `Helvetica
4475	Neue LT Com 65 Medium' at 11ppem.
4476
4477	Thanks to Greg Hitchcock who explained this behaviour.

4482
4483	Copy -mcpu=* & -march=* options from CFLAGS to LDFLAGS.
4484
4485	* builds/unix/configure.raw: Consider recent gcc-standard
4486	flags to specify architecture in CFLAGS & LDFLAGS
4487	harmonization.  Requested by Savannah bug #32114, to
4488	support multilib feature of BuildRoot SDK correctly.
4489
44902011-01-15  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4491
4492	Fix off-by-one bug in CFLAGS & LDFLAGS harmonizer.
4493
4494	* builds/unix/configure.raw: Some important options that
4495	included in CFLAGS but not in LDFLAGS are copied to
4496	LDFLAGS, but the last option in CFLAGS was not checked.

4506
4507	[raster] Reduce jitter value.
4508
4509	This catches a rendering problem with glyph `x' from Tahoma at
4510	10ppem.  It seems that the increase of the precision in the change
4511	from 2009-06-11 makes a larger jitter value unnecessary.
4512
4513	* src/raster/ftraster.c (Set_High_Precision): Implement it.
4514
45152011-01-13  Werner Lemberg  <wl@gnu.org>
4516
4517	[raster] Handle drop-outs at glyph borders according to Microsoft.
4518
4519	If a drop-out rule would switch on a pixel outside of the glyph's
4520	bounding box, use the right (or top) pixel instead.  This is an
4521	undocumented feature, but some fonts like `Helvetica Neue LT Com 65
4522	Medium' heavily rely on it.
4523
4524	Thanks to Greg Hitchcock who explained this behaviour.
4525
4526	* src/raster/ftraster.c (Vertical_Sweep_Drop,
4527	Horizontal_Sweep_Drop): Implement it.

4531	[cache] Fix Savannah bug #31923, patch drafted by Harsha.
4532
4533	When a node comparator changes the cached nodes during the
4534	search of a node matching with queried properties, the
4535	pointers obtained before the function should be updated to
4536	prevent the dereference to freed or reallocated nodes.
4537	To minimize the rescan of the linked list, the update is
4538	executed when the comparator notifies the change of cached
4539	nodes. This change depends previous change:
4540	38b272ffbbdaae276d636aec4ef84af407d16181
4541
4542	* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Rescan the
4543	top node if the cached nodes are changed.
4544	* src/cache/ftccache.c (FTC_Cache_Lookup): Ditto.
4545
45462011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4547
4548	[cache] Notice if a cache query induced the node list change.
4549
4550	Some node comparators (comparing the cache node contents and the
4551	properties specified by the query) can flush the cache node to
4552	prevent the cache inflation.  The change may invalidate the pointers
4553	to the node obtained before the node comparison, so it should be
4554	noticed to the caller.  The problem caused by the cache node
4555	changing is reported by Harsha, see Savannah bug #31923.
4556
4557	* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new argument
4558	`FT_Bool* list_changed' to indicate the change of the cached nodes
4559	to the caller.
4560	(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes by
4561	`_list_changed'.
4562	(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
4563	and update it when `FTC_Manager_FlushN' flushes any nodes.
4564
4565	* src/cache/ftccback.h (ftc_snode_compare): Updated to fit with new
4566	FTC_Node_CompareFunc type.
4567	(ftc_gnode_compare): Ditto.
4568
4569	* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to use
4570	TRUE/FALSE macros.
4571	(ftc_basic_gnode_compare_faceid): New argument `FT_Bool*
4572	list_changed' to indicate the change of the cache nodes (anyway, it
4573	is always FALSE).
4574
4575	* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to use
4576	TRUE/FALSE macros.
4577	(ftc_cmap_node_compare): New argument `FT_Bool* list_changed' to
4578	indicate the change of the cache nodes (anyway, it is always FALSE).
4579	(ftc_cmap_node_remove_faceid): Ditto.
4580
4581	* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL pointer to
4582	`FTC_CACHE_TRYLOOP_END', because the result is not needed.
4583	(FTC_Cache_Lookup): Watch the change of the cache nodes by
4584	`list_changed'.
4585	(FTC_Cache_RemoveFaceID): Ditto.
4586
4587	* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to use
4588	TRUE/FALSE macros.
4589	(ftc_gnode_compare): New argument `FT_Bool* list_changed' to
4590	indicate the change of the cache nodes (anyway, it is always FALSE).
4591	(FTC_GNode_Compare): New argument `FT_Bool* list_changed' to be
4592	passed to `ftc_gnode_compare'.
4593	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
4594
4595	* src/cache/ftcsbits.c (ftc_snode_compare): New argument `FT_Bool*
4596	list_changed' to indicate the change of the cache nodes, anyway.  It
4597	is updated by `FTC_CACHE_TRYLOOP'.
4598	(FTC_SNode_Compare): New argument `FT_Bool* list_changed' to be
4599	passed to `ftc_snode_compare'.
4600	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
4601
46022011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4603
4604	[cache] Fit `FTC_GNode_Compare' to `FTC_Node_CompareFunc'.
4605
4606	* src/cache/ftcglyph.h (FTC_GNode_Compare): Add the 3rd
4607	argument `FTC_Cache  cache' to fit FTC_Node_CompareFunc
4608	prototype.
4609	* src/cache/ftcglyph.c (FTC_GNode_Compare): Ditto. Anyway,
4610	`cache' is not used by its child `ftc_gnode_compare'.
4611
46122011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4613
4614	[cache] Deduplicate the code to get the top node by a hash.
4615
4616	There are several duplicated code fragments getting the top node
4617	from a cache by a given hash, like:
4618
4619	    idx = hash & cache->mask;
4620	    if ( idx < cache->p )
4621	      idx = hash & ( cache->mask * 2 + 1 );
4622	    pnode = cache->buckets + idx;
4623
4624	To remove duplication, a cpp-macro to do same work
4625	`FTC_NODE__TOP_FOR_HASH' is introduced.  For non-inlined
4626	configuration, non-`ftc_get_top_node_for_hash' is also introduced.
4627
4628	* src/cache/ftccache.h (FTC_NODE__TOP_FOR_HASH): Declare
4629	and implement inlined version.
4630	(FTC_CACHE_LOOKUP_CMP): Use `FTC_NODE__TOP_FOR_HASH'.
4631	* src/cache/ftccache.c (ftc_get_top_node_for_hash): Non-inlined
4632	version.
4633	(ftc_node_hash_unlink): Use `FTC_NODE__TOP_FOR_HASH'.
4634	(ftc_node_hash_link): Ditto.
4635	(FTC_Cache_Lookup): Ditto.
4636
46372011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4638
4639	[cache] inline-specific functions are conditionalized.
4640
4641	* src/cache/ftcglyph.c (FTC_GNode_Compare): Conditionalized for
4642	inlined configuration.  This function is a thin wrapper of
4643	`ftc_gnode_compare' for inlined `FTC_CACHE_LOOKUP_CMP' (see
4644	`nodecmp' argument).  Under non-inlined configuration,
4645	`ftc_gnode_compare' is invoked by `FTC_Cache_Lookup', via
4646	`FTC_Cache->clazz.node_compare'.
4647
4648	* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
4649	* src/cache/ftcsbits.c (FTC_SNode_Compare): Ditto, for
4650	`ftc_snode_compare'.
4651	* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
4652
46532011-01-09  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>
4654
4655	[cache] Correct a type mismatch under non-inlined config.
4656
4657	* src/cache/ftcglyph.h (FTC_GCACHE_LOOKUP_CMP): `FTC_GCache_Lookup'
4658	takes the node via a pointer `FTC_Node*', differently from cpp-macro
4659	`FTC_CACHE_LOOKUP_CMP'.
4660

4662
4663	Update Jamfile to include Bzip2 support.
4664
4665	* Jamfile: Include src/bzip2 to project.
4666	Comments for lzw, gzip, bzip2 are changed to clarify that
4667	they are for compressed PCF fonts, not others.
4668	(e.g. compressed BDF fonts are not supported yet)
4669

4715
4716	* builds/unix/configure.raw: Remove `SYSTEM_BZ2LIB' macro.
4717
4718	SYSTEM_ZLIB is used to switch the builtin zlib source
4719	or system zlib source out of FreeType2.  But ftbzip2
4720	module has no builtin bzip2 library and always requires
4721	system bzip2 library.  Thus SYSTEM_BZ2LIB is always yes,
4722	it is not used.

47652010-12-25  Harsha  <mm.harsha@gmail.com>
4766
4767	Apply Savannah patch #7422.
4768
4769	If we encounter a space in a string then the sbit buffer is NULL,
4770	height and width are 0s.  So the check in ftc_snode_compare will
4771	always pass for spaces (comparision with 255).  Here the comments
4772	above the condition are proper but the implementation is not.  When
4773	we create an snode I think it is the proper way to initialize the
4774	width to 255 and then put a check for being equal to 255 in snode
4775	compare function.
4776
4777	* src/cache/ftcsbits.c (FTC_SNode_New): Initialize sbit widths with
4778	value 255.

4961	[cache] Change the hash types to FT_PtrDist.
4962
4963	On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
4964	variables are inappropriate to calculate hash values
4965	from the memory address (64-bit).  The hash variables
4966	are extended from FT_ULong to FT_PtrDist and new
4967	hashing macro functions are introduced.  The hash
4968	values on 16-bit memory platforms are changed, but
4969	ILP32 and LP64 are not changed.  The hash value in
4970	the cache subsystem is not reverted to the memory
4971	address, so using signed type FT_PtrDist is safe.
4972
4973	* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash

5015
5016	On LLP64 platforms (e.g. Win64), unsigned long (32-bit)
5017	cannot cover the memory address (64-bit).  `FT_MEM_VAL' is
5018	used for hashing only and not dereferred, so using signed

5034
5035	* src/raster/ftraster.c (New_Profile): Replace "%lx" by "%p".

5050	[raccess] Skip unrequired resource access rules by Darwin VFS.
5051
5052	When a resource fork access rule by Darwin VFS could open the
5053	resource fork but no font is found in it, the rest of rules
5054	by Darwin VFS are skipped.  It reduces the warnings of the
5055	deprecated resource fork access method by recent Darwin kernel.
5056	Fix MacPorts ticket #18859:
5057		http://trac.macports.org/ticket/18859
5058
5059	* src/base/ftobjs.c (load_face_in_embedded_rfork):
5060	When `FT_Stream_New' returns FT_Err_Cannot_Open_Stream, it
5061	means that the file is possible to be `fopen'-ed but zero-sized.
5062	Also there is a case that the resource fork is not zero-sized,
5063	but no supported font exists in it.  If a rule by Darwin VFS
5064	falls into such cases, there is no need to try other Darwin VFS
5065	rules anymore.  Such cases are marked by vfs_rfork_has_no_font.
5066	If it is TRUE, the Darwin VFS rules are skipped.

5070	[raccess] Grouping resource access rules based on Darwin VFS.
5071
5072	MacOS X/Darwin kernel supports a few tricky methods to access
5073	a resource fork via ANSI C or POSIX interface.  Current resource
5074	fork accessor tries all possible methods to support all kernels.
5075	But if a method could open a resource fork but no font is found,
5076	there is no need to try other methods older than tested method.
5077	To determine whether the rule index is for Darwin VFS, a local
5078	function `ftrfork.c::raccess_rule_by_darwin_vfs' is introduced.
5079	To use this function in ftobjs.c etc but it should be inlined,
5080	it is exposed by ftbase.h.
5081
5082	* src/base/ftrfork.c (FT_RFork_Rule): New enum type to identify
5083	the rules to access the resource fork.
5084	(raccess_guess_rec): New structure to bind the rule function and
5085	rule enum type.
5086	(FT_Raccess_Guess): The list of the rule functions is replaced by
5087	(raccess_guess_table): This.  This is exposed to be used by other
5088	intra module functions.
5089	(raccess_rule_by_darwin_vfs): A function to return a boolean
5090	if the rule specified by the rule index is based on Darwin VFS.

5099	For cross-platform consistency, all stream drivers should act
5100	same.
5101

5349	Ignore the environmental setting of LIBTOOL.
5350	Patch is suggested by Adrian Bunk, to prevent unexpected
5351	reflection of environmental LIBTOOL.  See:
5352	http://savannah.nongnu.org/patch/?7290
5353
5354	* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
5355	$(FT_LIBTOOL_DIR)/libtool.  FT_LIBTOOL_DIR is set to $(BUILD_DIR)
5356	by default.
5357	* configure: When configured for the building out of source tee,
5358	FT_LIBTOOL_DIR is set to $(OBJ_DIR).

5369
5370	[truetype] Prevent bytecode reuse after the interpretation error.
5371
5372	* src/truetype/ttinterp.c (free_buffer_in_size): New function to
5373	free the buffer allocated during the interpretation of this glyph.
5374	(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
5375	an error occurs in the bytecode interpretation.  The interpretation
5376	of invalid bytecode may break the function definitions and referring
5377	them in later interpretation is danger.  By unsetting these flags,
5378	`fpgm' and `prep' tables are executed again in next interpretation.
5379
5380	This fixes Savannah bug #30798, reported by Robert Święcki.

5402	Force hinting when the font lacks its familyname.
5403
5404	In Type42 or Type11 font embedded in PostScript & PDF, TrueType sfnt
5405	stream may lack `name' table because they are not required.  Hinting
5406	for nameless fonts is safer for PDFs including embedded Chinese
5407	fonts.  Written by David Bevan, see:

5811	length of the segment is not cared at all.  According to Adobe

6161	[psaux] Fix Savannah bug #29846.
6162
6163	Previously we discovered fonts which used `setcurrentpoint' to set
6164	the initial point of a contour to 0,0.  This caused FreeType to
6165	raise an error, because the `setcurrentpoint' operator is only
6166	supposed to be used with the results from an OtherSubr subroutine.
6167
6168	This was fixed by simply ignoring the error and carrying on.
6169
6170	Now we have found a font which uses setcurrentpoint to actually
6171	establish a non-zero point for a contour during the course of a
6172	glyph program.  FWIW, these files may be produced by an application
6173	called `Intaglio' on the Mac, when converting TrueType fonts to
6174	Type 1.
6175
6176	The fix allows the new invalid behaviour, the old invalid behaviour
6177	and real proper usage of the operator to work the same way as Adobe
6178	interpreters apparently do.
6179
6180	* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Make
6181	`setcurrentpoint' use the top two elements of the stack to establish
6182	unconditionally the current x and y coordinates.
6183
6184	Make the `flex' subroutine handling (OtherSubr 0) put the current
6185	x,y coordinates onto the stack, instead of two dummy uninitialised
6186	values.
