31e726d9	2013-09-20T07:20:53	Fix vertical size of emboldened glyphs. Cf. https://bugzilla.gnome.org/show_bug.cgi?id=686709 * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Adjust `horiBearingY' also.
3f542498	2013-09-11T23:08:31	[autofit] Improve Hebrew rendering. This change introduces a new blue zone property `AF_BLUE_PROPERTY_LATIN_LONG' to make the auto-hinter ignore short top segments. * src/autofit/afblue.dat: Fix Hebrew blue strings. Use AF_BLUE_PROPERTY_LATIN_LONG for AF_BLUE_STRING_HEBREW_TOP. * src/autofit/afblue.hin (AF_BLUE_PROPERTY_LATIN_LONG): New macro. * src/autofit/afblue.c, src/autofit/afblue.h: Updated. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Handle `AF_LATIN_IS_LONG_BLUE'. * src/autofit/aflatin.h (AF_LATIN_IS_LONG_BLUE): New macro.
85a7fdf3	2013-08-29T21:03:05	[sfnt] Fix frame access while reading WOFF table directory. * src/sfnt/sfobjs.c (woff_open_font): Using single memory frame while reading the directory entries for the whole loop.
d689d1cf	2013-08-29T17:53:40	Implement support for WOFF containers. We simply synthesize a SFNT from the WOFF, create a memory stream for the new data, and load the SFNT as usual. Does NOT add any API to access WOFF metadata or private blocks. * include/freetype/internal/tttypes.h (WOFF_HeaderRec, WOFF_TableRec): New structures. * include/freetype/tttags.h (TTAG_wOFF): New macro. * src/base/ftobjs.c (FT_Open_Face): Set `stream' after calling `open_face'. * src/sfnt/sfobjs.c [FT_CONFIG_OPTION_SYSTEM_ZLIB]: Include `FT_GZIP_H'. (WRITE_BYTE, WRITE_USHORT, WRITE_ULONG): New temporary macros for writing to a stream. (sfnt_stream_close, compare_offsets, woff_open_font): New functions. (sfnt_open_font): Handle `TTAG_wOFF'. (sfnt_init_face): Set `stream' after calling `sfnt_open_font'. * src/truetype/ttobjs.c (tt_face_init): Set `stream' after calling `sfnt->init_face'. * src/base/ftobjs.c (open_face): Use a pointer to FT_Stream as an argument so that a changed stream survives. Update callers.
dc240524	2013-08-29T17:53:24	[gzip] New function `FT_Gzip_Uncompress'. This is modeled after zlib's `uncompress' function. We need this for WOFF support. * include/freetype/ftgzip.h, src/gzip/ftgzip.c (FT_Gzip_Uncompress): New function. * src/gzip/rules.mk: Rewrite to better reflect dependencies.
5195ecd6	2013-08-28T17:41:21	[autofit] Fix `make multi' compilation. * src/autofit/afblue.cin, src/autofit/afblue.c: Don't include `afblue.h' but `aftypes.h'. * src/autofit/afcjk.c: Don't include `aftypes.h' but `afglobal.h'.

c799dd67	2013-08-27T21:46:03	* src/sfnt/ttload.c (tt_face_load_font_dir): Fix sign typos.
bd3849e7	2013-08-27T21:43:38	FT_Open_Face: Improve external stream handling. If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to... (open_face): This function.
bcd8c0b0	2013-08-27T21:36:03	Remove `FT_SqrtFixed' function. It's no longer used. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c: Do it.
71c0ad65	2013-08-27T21:30:09	Whitespace.
5e53db25	2013-08-27T18:37:39	[autofit] While tracing, report script names instead of ID values. * src/autofit/afglobal.c (af_script_names) [FT_DEBUG_LEVEL_TRACE]: New array. * src/autofit/afglobal.h: Updated. * src/autofit/afcjk.c (af_cjk_metrics_init_widths, af_cjk_hint_edges): Use `af_script_names'. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_hint_edges): Ditto.
278f64b3	2013-08-26T20:20:03	[autofit] Report used script while hinting a glyph. * src/autofit/afcjk.c (af_cjk_hint_edges), src/autofit/aflatin.c (af_latin_hint_edges): Implement it.
371f5c3b	2013-08-26T20:11:24	[autofit] Add support for Hebrew script. * src/autofit/afblue.dat: Add blue strings for Hebrew. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/aflatin.c (af_hebr_uniranges): New array. (af_hebr_script_class): New script. * src/autofit/aflatin.h, src/autofit/afscript.h: Updated.
098121db	2013-08-26T18:54:05	[autofit] Improve tracing messages. * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Mention script ID in tracing message. (af_cjk_metrics_init_blues): Initialize `axis' outside of the inner loop. Improve tracing messages. (af_cjk_hint_edges) [FT_DEBUG_LEVEL_TRACE]: New variable `num_actions' to count hinting actions. Improve tracing messages. * src/autofit/aflatin.c (af_latin_metrics_init_widths): Mention script ID in tracing message. (af_latin_metrics_init_blues, af_latin_hint_edges): Improve tracing messages.
ffee64af	2013-08-26T12:55:48	Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all. With this change, all font loading routines emit a tracing message at level 1, making it easier to select tracing output (for example using F2_DEBUG="any:1 afhints:7 aflatin:7"). * src/bdf/bdfdrivr.c (BDF_Glyph_Load): Add tracing message. * src/cff/cffdrivr.c (cff_glyph_load): Ditto. * src/cff/cffgload.c (cff_decoder_prepare): Improve tracing messages. * src/cid/cidgload.c (cid_load_glyph): Use level 1 for tracing message. * src/pcf/pcfdrivr.c (PCF_Glyph_Load): Ditto. * src/pfr/pfrobjs.c (pfr_slot_load): Add tracing message. * src/truetype/ttgload.c (TT_Load_Glyph): Ditto. * src/type1/t1gload.c (T1_Load_Glyph): Ditto. * src/type42/t42objs.c (T42_GlyphSlot_Load): Ditto. * src/winfonts/winfnt.c (FNT_Load_Glyph): Ditto.
33655a96	2013-08-26T09:58:50	[autofit] Fix script selection. * src/autofit/afglobal.c (af_face_globals_get_metrics): Use `AF_SCRIPT_DFLT', not value 0. Simplify code. * src/autofit/afscript.h: Sort by script name.
92f5a047	2013-08-26T09:22:27	[autofit] Make `dummy' hinter work as expected. * src/autofit/afdummy.c (af_dummy_hints_init): Properly set scaling information. (af_dummy_hints_apply): Scale the glyphs.
c1eb4459	2013-08-25T19:47:26	[autofit] Make `cjk' module use blue stringsets. * src/autofit/afcjk.c (AF_CJK_MAX_TEST_CHARACTERS): Removed. (af_cjk_hani_blue_chars): Removed. (AF_CJK_BLUE_TYPE_): Removed. (af_cjk_metrics_init_blues): Replace AF_CJK_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Instead of three dimensions (as used in the old blue string array) we now use properties to do the same, saving one loop nesting level. src/autofit/afcjk.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE, AF_CJK_IS_RIGHT_BLUE): New macros, to be used in `af_cjk_metrics_init_blues'. (AF_CJK_BLUE_IS_RIGHT): Remove this now redundant enum value. (AF_CJK_BLUE_IS_TOP): Renamed to... (AF_CJK_BLUE_TOP): This. (AF_CJK_MAX_BLUES): Remove. (AF_CJKAxisRec): Updated.
5c4a23a4	2013-08-25T19:29:07	[autofit] Typo. * src/autofit/afblue.hin, src/autofit/afblue.c (GET_UTF8_CHAR): Use cast.
306f8c5d	2013-08-25T13:07:08	[autofit] Synchronize `cjk' with `latin' module (and vice versa). * src/autofit/afcjk.c (af_cjk_metrics_init_widths): Add tracing messages. (af_cjk_metrics_init_blues): Don't pass blue string array as argument but use the global array directly. Use `outline' directly. Update and add tracing messages. (af_cjk_metrics_init): Simplify code. (af_cjk_metrics_scale_dim): Improve tracing message. (af_cjk_metrics_scale): Synchronize. * src/autofit/aflatin.c (af_latin_metrics_init_widths, af_latin_metrics_init_blues): Improve and add tracing messages.
0975d685	2013-08-25T08:37:47	[autofit] Make `latin' module use blue stringsets. * src/autofit/aflatin.c (AF_LATIN_MAX_TEST_CHARACTERS): Removed. (af_latin_blue_chars): Removed. (af_latin_metrics_init_blues): Replace AF_LATIN_MAX_TEST_CHARACTERS with AF_BLUE_STRING_MAX_LEN. Change loops to use offsets (in file `afblue.h') into the new arrays `af_blue_stringsets' and `af_blue_strings' (in file `afblue.c'). Use `AF_LATIN_IS_SMALL_TOP_BLUE' macro. * src/autofit/aflatin.h: Remove old enumeration values superseded by the new data in `afblue.h'. (AF_LATIN_IS_TOP_BLUE): Updated definition. (AF_LATIN_IS_SMALL_TOP_BLUE): New macro. (AF_LATIN_MAX_BLUES): Remove. (AF_LatinAxisRec): Updated.
db3e5b93	2013-08-25T08:23:22	[autofit] Add blue stringsets. * src/autofit/aftypes.h: Include `afblue.h'. (AF_ScriptClassRec): Add `blue_stringset' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/autofit.c: Include `afblue.c'. * src/autofit/afcjk.c (af_hani_script_class), src/autofit/afdummy.c (af_dflt_script_class), src/autofit/afindic.c (af_deva_script_class), src/autofit/aflatin.c (af_latn_script_class), src/autofit/aflatin2.c (af_ltn2_script_class): Updated. * src/autofit/rules.mk (AUTOF_DRV_SRC): Add `afblue.c'.
8b8be783	2013-08-25T08:01:41	[autofit] Introduce data file for blue strings. The idea is to have a central file which gets processed by a Perl script to create proper `.c' and `.h' files using templates. There are two other reasons to do that: . The data file should be easily readable. We use UTF-8 encoding which then gets converted to single bytes. . Since the number of supported scripts will increase soon, the current usage of blue string arrays is a waste of space. Using the Perl script it is possible to imitate jagged arrays, defining enumeration constants as offsets into the arrays. This commit only adds files without changing any functionality. * src/autofit/afblue.dat: New data file. * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files for... * src/autofit/afblue.c, src/autofit/afblue.c: New source files. To avoid a dependency on Perl, we add them too.
fc32e1c8	2013-08-19T22:57:05	[base] Enable new algorithm for BBox_Cubic_Check. * src/base/ftbbox.c: Enable new BBox_Cubic_Check algorithm, remove the old one. Improve comments.
32a7d870	2013-08-17T22:19:21	[base] Clean up BBox_Conic_Check. * src/base/ftbbox.c (BBox_Conic_Check): Remove redundant checks for extremum at the segment ends, which are already within the bbox. Slightly modify calculations.
1a9c3d14	2013-08-15T22:51:42	[base] Finish experimental (disabled) BBox_Cubic_Check implementation. * src/base/ftbbox.c (BBox_Cubic_Check): Scale arguments to improve accuracy and avoid overflows.
61a65510	2013-08-13T22:28:57	[base] Refactor experimental (disabled) BBox_Cubic_Check. * src/base/ftbbox.c (BBox_Cubic_Check): Implement the minimum search as the mirror image of the maximum search.
9bcfab87	2013-08-06T08:55:19	Fix Savannah bug #39702. * src/cff/cffload.c (cff_index_get_pointers): Check for `cur_offset != 0'; this stronger test is mandated by the CFF specification. Fix test for INDEX structures which have one or more empty entries at the end.
a32682f1	2013-08-06T00:21:46	Fix gcc pragmas, part 2. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): `#pragma gcc diagnostic {push,pop}' has been introduced with gcc version 4.6.
69e524d5	2013-08-05T23:38:32	Fix gcc pragmas. * src/truetype/ttinterp.c (TT_MulFix14_long_long, TT_DotFix14_long_long): Older gcc versions don't accept diagnostic pragmas within a function body.

cc25e3ae	2013-08-05T08:46:15	[autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary.
ba9cf52d	2013-08-05T07:00:59	Comment typo.
fb09a51f	2013-08-04T18:24:02	Add comments to `ft_corner_is_flat'.
b8bf8b54	2013-08-04T09:25:24	[autofit] Update comments.
6d3c10e0	2013-08-02T20:47:15	Typo.
456cc440	2013-08-02T20:25:21	[autofit] Move declaration of scripts into separate file. This has the benefit that we don't need to duplicate the data at different places. * src/autofit/afscript.h: New file. * src/autofit/aftypes.h (AF_Script): Include `afscript.h' to define the enumeration values. * src/autofit/afglobal.c: Include `afscript.h' to get the script specific header files. (af_script_classes): Include `afscript.h' to fill this array. * src/autofit/afpic.c: Include `afscript.h' to get the script specific header files. (autofit_module_class_pic_init): Include `afscript.h' for initialization. * src/autofit/afpic.h (AF_SCRIPT_CLASSES_COUNT, AF_SCRIPT_CLASSES_REC_COUNT): Removed. Use `AF_SCRIPT_MAX' instead. * src/autofit/rules.mk (AUTOF_DRV_H): Updated.
773601da	2013-08-02T19:51:17	[autofit] Move declaration of writing systems into separate file. This has the benefit that we don't need to duplicate the data at different places. * src/autofit/afwrtsys.h: New file. * src/autofit/aftypes.h (AF_WritingSystem): Include `afwrtsys.h' to define the enumeration values. * src/autofit/afglobal.c: Include `afwrtsys.h' to get the writing system specific header files. Include `afpic.h'. (af_writing_system_classes): Include `afwrtsys.h' to fill this array. * src/autofit/afpic.c: Include `afwrtsys.h' to get the writing system specific header files. (autofit_module_class_pic_init): Include `afwrtsys.h' for initialization. * src/autofit/afpic.h (AF_WRITING_SYSTEM_CLASSES_COUNT, AF_WRITING_SYSTEM_CLASSES_REC_COUNT): Removed. Use `AF_WRITING_SYSTEM_MAX' instead.
74a9b670	2013-08-02T14:53:32	[sfnt] Fix compilation with g++. * src/sfnt/pngshim.c (error_callback, read_data_from_FT_stream): Use cast. (Load_SBit_Png): Pacify compiler.
89a529f3	2013-08-02T14:50:23	[autofit] Fix `make multi'. * include/freetype/config/ftconfig.h (FT_LOCAL_ARRAY, FT_LOCAL_ARRAY_DEF): New macros. * src/autofit/afglobal.c (af_writing_system_classes, af_script_classes): Use FT_LOCAL_ARRAY_DEF. * src/autofit/afglobal.h: Declare `af_writing_system_classes' and `af_script_classes'. * src/autofit/afloader.c: Include `afpic.h'.
e8ed2d62	2013-08-01T12:20:20	Another round of cppcheck nitpicks. The call was (from the top-level of the FreeType tree): cppcheck --force \ --enable=all \ -I /usr/include \ -I /usr/local/include \ -I /usr/lib/gcc/i586-suse-linux/4.7/include \ -I include \ -I include/freetype \ -I include/freetype/config \ -I include/freetype/internal \ -DFT2_BUILD_LIBRARY \ . &> cppcheck.log using cppcheck git commit f7e93f99. Note that cppcheck still can't handle `#include FOO' (with `FOO' a macro). / Improve variable scopes. / Remove redundant initializations which get overwritten. * src/gxvalid/*: Comment out redundant code or guard it with FT_DEBUG_LEVEL_TRACE.
72f5ff5b	2013-07-31T22:49:29	[autofit] Introduce `writing systems'. This patch adds a new top level to the auto-hinter's script class hierarchy. It defines `writing systems' which can contain multiple scripts. For example, the `latin' writing system (in file `aflatin.c') is able to support scripts like Latin, Cyrillic, Armenian, etc., which can be handled similarly. Scripts are now named using four-letter OpenType tags. * src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members to... (AF_WritingSystemClassRec): This new structure.

cc34efca	2013-07-31T22:55:50	Minor.
f2e7f1e1	2013-07-30T13:32:57	2013-07-30 Behdad Esfahbod <behdad@google.com> Prevent division by zero by a transparent color. * src/base/ftbitmap.c (ft_gray_for_premultiplied_srgb_bgra): Return 0 immediately, when alpha channel is zero.
21c32b08	2013-07-25T21:53:18	Add FT_FACE_FLAG_COLOR and FT_HAS_COLOR. Also disambiguate Google's color bitmap tables. * include/freetype/freetype.h (FT_FACE_FLAG_COLOR, FT_HAS_COLOR): New macros. * include/freetype/internal/tttypes.h (TT_SbitTableType): Add TT_SBIT_TABLE_TYPE_CBLC. * src/sfnt/sfobjs.c (sfnt_load_face): Handle FT_FACE_FLAG_COLOR. * src/sfnt/ttsbit.c (tt_face_load_sbit, tt_face_load_strike_metrics, tt_face_load_sbit_image): Handle TT_SBIT_TABLE_TYPE_CBLC.

ff269528	2013-07-20T08:02:39	[sfnt] Fix `sbix' table version handling. * src/sfnt/ttsbit.c (tt_face_load_sbit) [TT_SBIT_TABLE_TYPE_SBIX]: USHORT version numbers are to be considered as `minor'.
05c1421f	2013-07-19T23:11:23	[autofit] Fix segment classification for blue zones. The old code (essentially unchanged since the very beginning) incorrectly handled this configuration x -o- x / \ / \ / \ o o as flat and this o o / / x\| x\| \| \| o---------------o as round. (`o' and `x' are on and off points, respectively). This is a major change which should improve the rendering results enormously for many TrueType fonts, especially in the range approx. 20-40ppem, fixing the appearance of many overshoots. * src/autofit/aflatin.c (af_latin_metrics_init_blues): Look at the first and last points of the segment, not the points right before and after.
778a7e6a	2013-07-19T14:28:28	[sfnt] `sbix' fix-ups. * src/sfnt/sfobjs.c (sfnt_load_face): Apple's `sbix' color bitmaps are rendered scaled and then the `glyf' outline rendered on top. We don't support that yet, so just ignore the `glyf' outline and advertise it as a bitmap-only font. * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) [TT_SBIT_TABLE_TYPE_SBIX]: Return metrics in 26.6 units. (tt_face_load_sbix_image): Typo.
01705395	2013-07-18T13:13:12	[sfnt] Add support for Apple's `sbix' color bitmap table. * include/freetype/internal/tttypes.h (TT_SBit_MetricsRec): Widen fields to FT_Short and FT_UShort, respectively. (TT_SBitTableType): New enumeration. (TT_FaceRec): Add `sbit_table_type' field. * include/freetype/tttags.h (TTAG_sbix): New macro. * src/sfnt/pngshim.c (Load_SBit_Png): Pass a more generic FT_GlyphSlot argument instead FT_Bitmap. Add flag to control map and metrics handling. Update all users. * src/sfnt/ttsbit.c: Include `ttmtx.h'. (tt_face_load_eblc): Renamed to... (tt_face_load_sbit): This. Handlic `sbix' bitmaps. (tt_face_free_eblc): Renamed to... (tt_face_load_sbit): This. Updated. (tt_face_load_strike_metrics): Handle `sbix' bitmaps. (tt_face_load_sbix_image): New function. (tt_sbit_decoder_alloc_bitmap, tt_sbit_decoder_load_image, tt_sbit_decoder_load_byte_aligned, tt_sbit_decoder_load_bit_aligned, tt_sbit_decoder_load_compound, tt_sbit_decoder_load_png, tt_sbit_decoder_load_image, tt_sbit_decoder_load_bitmap): Don't pass and handle load flags.

760d342d	2013-05-29T11:36:18	Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng.

If the font's `clazz->init_face' function wants to swap to new stream, handling of whether original stream was external could result to either memory leak or double free. Mark externality into face flags before calling `init_face' such that the clazz can handle external streams properly. * src/base/ftobjs.c (FT_Open_Face): Move code to set FT_FACE_FLAG_EXTERNAL_STREAM to...

Better tracing of loaded glyphs. Previously, the loading of a glyph was traced at level 4, if at all.

[autofit] Introduce data file for blue strings. The idea is to have a central file which gets processed by a Perl script to create proper `.c' and `.h' files using templates. There are two other reasons to do that: . The data file should be easily readable. We use UTF-8 encoding which then gets converted to single bytes. . Since the number of supported scripts will increase soon, the current usage of blue string arrays is a waste of space. Using the Perl script it is possible to imitate jagged arrays, defining enumeration constants as offsets into the arrays. This commit only adds files without changing any functionality. * src/autofit/afblue.dat: New data file. * src/tools/afblue.pl: New Perl script for processing `afblue.dat'. * src/autofit/afblue.cin, src/autofit/afblue.hin: New template files for... * src/autofit/afblue.c, src/autofit/afblue.c: New source files. To avoid a dependency on Perl, we add them too.

[autofit] Improve handling of `near' points. Points which are very near to each other are now marked as such. The `weak' flag is then computed by using the `in' vector of the first and the `out' vector of the last point of a group of near points. For example, this fixes the rendering of glyph `Oslash' in `Roboto-Thin.ttf'. * src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'. * src/autofit/afhints.c (af_glyph_hints_reload): Introduce the heuristic value `near_limit' to decide whether the current point is near to the previous one, then set `AF_FLAG_NEAR' accordingly. Store good `in' vector (of last non-near point) in `last_good_in_{x,y}' and use it as an argument to `ft_corner_is_flat' if necessary.

If memory allocations fail at certain points while opening a font, FreeType can either crash due to a NULL dereference or leak memory. * include/freetype/internal/ftobjs.c (FT_Face_InternalRec, FT_LibraryRec): Make `refcount' a signed integer. If, for example, FT_Open_Face() fails in a memory allocation before the face's reference count is set to 1, a subsequent `FT_Done_Library' call would otherwise loop over `FT_Done_Face' 2^32 times before freeing the face. * src/base/ftobjs.c (open_face): Initialize `stream' and friends earlier.

Add support for color embedded bitmaps (eg. color emoji). A new load flag, FT_LOAD_COLOR, makes FreeType load color embedded-bitmaps, following this draft specification https://color-emoji.googlecode.com/git/specification/v1.html which defines two new SFNT tables, `CBDT' and `CBLC' (named and modeled after `EBDT' and `EBLC', respectively). The color bitmaps are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA pre-multiplied sRGB images. If PNG support is available, PNG color images as defined in the same proposed specification are supported also. Note that color bitmaps are converted to grayscale if client didn't ask for color. * builds/unix/configure.raw: Search for libpng. Add `--without-png' option. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_PNG): New macro. * include/freetype/freetype.h (FT_LOAD_COLOR): New load flag. * include/freetype/ftimage.h (FT_Pixel_Mode): Add `FT_PIXEL_MODE_BGRA'. * include/freetype/tttags.h (TTAG_CBDT, TTAG_CBLC): New tags. * src/base/ftbitmap.c (FT_Bitmap_Embolden): Updated.
