d38ba0c9	2010-09-19T20:51:19	Minor fixes. * src/cff/cffload.c (cff_charset_compute_cids): `charset->sids[i]' is `FT_UShort'. (cff_index_access_element): Don't use additions in comparison. * src/sfnt/ttpost.c (load_format_20): Make `post_limit' of type `FT_Long'. Don't use additions in comparison. Improve tracing messages. (load_format_25, load_post_names): Make `post_limit' of type `FT_Long'.
73aa20ca	2010-09-20T01:30:38	[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.
d2d843a0	2010-09-20T01:28:17	[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 about maximum CID in the font, but PostScript and PDF spec define that maximum CID is 0xFFFFU.
a0f43f20	2010-09-20T01:26:56	[cff] Make trace message in cff_charset_load() verbose. See Savannah bug #30975. * src/cff/cffload.c (cff_charset_load): Report the original `nleft' and truncated `nleft'.
b3e1954d	2010-09-20T01:22:34	[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.
5220ef58	2010-09-13T07:32:22	Fix minor issues reported by <muktha.narayan@wipro.com>. * src/autofit/aflatin.c (af_latin_compute_stem_width): Remove redundant conditional check. * src/base/ftsynth.c (FT_GlyphSlot_Embolden): Ditto. * src/cff/cffload.c (cff_encoding_load): Remove conditional check which always evaluates to `true'. * src/pshinter/pshalgo.c (ps_glyph_interpolate_strong_points): Ditto. * src/truetype/ttinterp.c (Ins_IUP): Ditto. * src/cid/cidgload.c (cid_slot_load_glyph): Don't check for NULL if value is already dereferenced. * src/winfonts/winfnt.c (FNT_Load_Glyph): Fix check of `face'.
0e95b3d1	2010-08-29T10:46:26	[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>.
223cb1b5	2010-08-06T06:55:09	[cff] Add comment to clarify current implementation of `pop' operator.
d9b3e394	2010-08-05T17:10:32	[cff] Don't use any values in decoder after parsing error. * src/cff/cffgload.c (cff_slot_load): Skip the evaluations of the values in decoder, if cff_decoder_parse_charstrings() returns any error.
11d65e8a	2010-08-04T14:43:29	[cff] Improve stack overflow test. * src/cff/cffgload.c (cff_decoder_parse_charstrings): Check stack after execution of operations too.
2de6b8a3	2010-07-17T13:39:50	[cff] Final try to fix `hintmask' and `cntrmask' limit check. Problem reported by Tobias Wolf <towolf@gmail.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: Sigh. I'm apparently too silly to fix this correctly in less than three tries.
d594202e	2010-07-11T00:31:17	Fix another case reported in Savannah bug #30373. Permit a face for Type1, Type42 and CFF without charmap, patch by Tor Andersson. * src/type1/t1objs.c (T1_Face_Init): Reset the error if it is FT_Err_No_Unicode_Glyph_Name. * src/type42/t42objs.c (T42_Face_Init): Ditto. * src/cff/cffobjs.c (cff_face_init): Ditto.
840f208d	2010-07-09T12:26:33	Use defined macros to set {platform,encoding}_id. * src/bdf/bdfdrivr.c: Include ttnameid.h and use macros to set charmap.{platfom,encoding}_id. * src/pcf/pcfdrivr.c: Ditto. * src/winfonts/winfnt.c: Ditto. * src/type1/t1objs.c: Ditto. * src/type42/t42objs.c: Ditto. * src/cff/cffobjs.c: Ditto. * src/pfr/pfrobjs.c: Ditto.

2dc76a46	2010-07-05T06:40:02	[cff] Next try to fix `hintmask' and `cntrmask' limit check. Problem reported by malc <av1474@comtv.ru>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_hintmask>: It is possible that there is just a single byte after the `hintmask' or `cntrmask', e.g., a `return' instruction.
0ae32718	2010-07-04T20:14:18	Restrict the number of the charmaps in a rogue-compatible mode. Fix for Savannah bug #30059. * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the minimum character code passed by a legacy rogue client by... * include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE): This. It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is undefined (thus the rogue client compatibility is not required). * src/cff/cffobjs.c (cff_face_init): Abort the automatic selection or synthesis of Unicode cmap subtable when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE. * src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE. * src/base/ftobjs.c (find_unicode_charmap): When Unicode charmap is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one. (find_variant_selector_charmap): When UVS charmap is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one. (FT_Select_Charmap): When a charmap matching with requested encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search earlier one. (FT_Set_Charmap): When a charmap matching with requested charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search earlier one. (FT_Get_Charmap_Index): When a requested charmap is found after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap index.
a874c7ec	2010-07-04T12:08:41	Check error value by `FT_CMap_New'. * src/cff/cffobjs.c (cff_face_init): Check error value by `FT_CMap_New'. * src/pfr/pfrobjs.c (pfr_face_init): Ditto. * src/type1/t1jobjs.c (T1_Face_Init): Ditto. * src/type42/t42jobjs.c (T42_Face_Init): Ditto.

63e7aac3	2010-02-10T07:13:27	Really fix Savannah bug #28678 (part 2). Since we consider `sbw' for the horizontal direction only, we still have to synthesize vertical metrics if the user wants to use the vertical writing direction. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_slot_load_glyph), src/type1/t1gload.c (T1_Load_Glyph): Synthesize vertical metrics (only) if FT_LOAD_VERTICAL_LAYOUT is set.
980b76ea	2010-02-10T07:02:43	Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of one direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it.
d9145241	2010-02-05T02:58:24	Prevent NULL pointer dereference passed to FT_Module_Requester.
f19e46f3	2010-01-27T10:04:50	Fix Savannah bug #28678. * src/cff/cffgload.c (cff_slot_load), src/cid/cidgload.c (cid_load_glyph): Handle vertical metrics correctly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Handle vertical metrics correctly. (T1_Load_Glyph): Don't synthesize vertical metrics.
2ad91580	2010-01-09T08:22:38	Whitespace.
7bdc1d59	2009-12-18T07:13:22	Fix Savannah bug #28320. There exist corrupt, subsetted fonts (embedded in PDF files) which contain a private dict that ends with an unterminated floating point number (no operator following). We now ignore this error (as acrobat does). * src/cff/cffparse.c (cff_parser_run): Don't emit a syntax error for unterminated floating point numbers.
012552f1	2009-11-04T10:06:04	Fix Savannah bug #27921. * src/cff/cffobjs.c (cff_face_init), src/cid/cidobjs.c (cid_face_init), src/type1/t1afm.c (T1_Read_Metrics), src/type1/t1objs.c (T1_Face_Init): Don't use unsigned constant values for rounding if the argument can be negative.
8821cc5d	2009-11-04T07:21:15	Add basic support for Type1 charstrings in CFF. * src/cff/cffgload.c (CFF_Operator, cff_argument_counts): Handle `seac', `sbw', and `setcurrentpoint' opcodes. (cff_compute_bias): Add parameter to indicate the charstring type. Update all callers. (cff_operator_seac): Add parameter for side bearing. (cff_decoder_parse_charstrings): Updated for more Type1 support.
2d15120c	2009-10-19T21:09:13	Fix handling of `get' and `put' CFF instructions. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_get, cff_op_put>: Appendix B of Adobe Technote #5177 limits the number of elements for the `get' and `put' operators to 32. * src/cff/cffgload.h (CFF_MAX_TRANS_ELEMENTS): Define. (CFF_Decoder): Use it for `buildchar' and remove `len_buildchar'.
d90567b1	2009-10-18T10:47:11	Fix handling of `dup' CFF instruction. Problem and solution reported by Ning Dong <flintning@163.com>. * src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_dup>: Increase `args' by 2, not 1.
0729bc9f	2009-09-10T16:09:55	[Win64] Improve the computation of random seed from stack address.
4694ea2b	2009-09-02T13:06:33	Improve vertical metrics calculation (Savannah bug #27364). The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Vertical metrics information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS was not defined. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec.
d77cd8ce	2009-08-27T00:10:56	Fix rendering of horizontally compressed CFFs. Bug reported by Ivan Nincic <inincic@pdftron.com>. * src/cff/cffgload.c (cff_slot_load): Thinko: Check `xx' element of `font_matrix' also. * docs/CHANGES: Updated.

ce33a312	2008-12-21T10:29:30	FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE.

Also provide 'fast loaders' for the TrueType, Type1 and CFF font drivers (more to come later) * autogen.sh: add checks for minimum version of the 'autotools' stuff.
da32d705	2008-08-06T09:09:41	Add one more example to the documentation of FT_Glyph_To_Bitmap.
eba3eeec	2008-08-04T15:54:24	* src/cff/cffparse.c (cff_parse_fixed_scaled): Fix thinko which resulted in incorrect scaling. This fixes Savannah bug #23973.
806f5934	2008-07-30T05:28:37	* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer assume that the first argument on the stack is the bottom-most element. Two reasons: o According to people from Adobe it is missing in the Type 2 specification that pushing of additional, superfluous arguments on the stack is prohibited. o Acroread in general handles fonts differently, namely by popping the number of arguments needed for a particular operand (as a PS interpreter would do). In case of buggy fonts this causes a different interpretation which of the elements on the stack are superfluous and which not. Since there are CFF subfonts (embedded in PDFs) which rely on Acroread's behaviour, FreeType now does the same.
bdcfddcd	2008-07-26T21:22:20	* src/cff/cffgload.c (cff_decoder_prepare, cff_decoder_parse_charstrings): Improve debug output.
bd48d35b	2008-07-16T07:05:11	Set FT_FACE_FLAG_CID_KEYED only if pure_cff is set.

5b631d89	2008-06-19T16:23:43	* src/cff/cffobjs.c (cff_face_init): Compute final `dict->units_per_em' value before assigning it to `cffface->units_per_EM'. Otherwise, CFFs without subfonts are be scaled incorrectly if the font matrix is non-standard. This fixes Savannah bug #23630. * docs/CHANGES: Updated.
6174e17c	2008-06-10T05:58:25	* Version 2.3.6 released. ========================= Tag sources with `VER-2-3-6'. * docs/CHANGES, docs/VERSION.DLL: Update documentation and bump version number to 2.3.6. * README, Jamfile (RefDoc), builds/win32/visualc/index.html, builds/win32/visualc/freetype.dsp, builds/win32/visualc/freetype.vcproj, builds/win32/visualce/index.html, builds/win32/visualce/freetype.dsp, builds/win32/visualce/freetype.vcproj: s/2.3.5/2.3.6/, s/235/236/. * include/freetype/freetype.h (FREETYPE_PATCH): Set to 6. * builds/unix/configure.raw (version_info): Set to 9:17:3. * include/freetype/internal/psaux.h (T1_BuilderRec): Remove `scale_x' and `scale_y'. * src/cff/cffgload.h (CFF_Builder): Remove `scale_x' and `scale_y'. * src/cff/cffparse.c: Include FT_INTERNAL_DEBUG_H. * src/cff/cffobjs.h: Include FT_INTERNAL_POSTSCRIPT_HINTS_H.

It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function.

(cff_parse_real): Rewritten to introduce a fourth parameter which returns the `scaling' of the real number so that we have no precision loss. This is not used yet. Update all callers. (cff_parse_fixed_thousand): Replace with... (cff_parse_fixed_scaled): This function. Update all callers.
de9479a0	2008-04-26T12:52:57	* include/freetype/internal/psaux.h (T1_BuilderRec): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/psaux/psobjs.c (t1_builder_init): Updated. * src/cff/cffgload.h (CFF_Builder): Mark `scale_x' and `scale_y' as obsolete since they aren't used. * src/cff/cffgload.c (cff_builder_init): Updated.

Really fix Savannah bug #28678 (part 1). After long discussion, we now consider the character width vector (wx,wy) returned by the `sbw' Type 1 operator as being part of *one* direction only. For example, if you are using the horizontal writing direction, you get the horizontal and vertical components of the advance width for this direction. Note that OpenType and CFF fonts don't have such a vertical component; instead, the GPOS table can be used to generate two-dimensional advance widths (but this isn't handled by FreeType). * include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add `advance_v' field to hold the vertical component of the advance value. * src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c (cff_slot_load), src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String), src/cid/cidgload.c (cid_load_glyph): Use it.

Improve vertical metrics calculation (Savannah bug #27364). The calculation of `vertBearingX' is not defined in the OTF font spec so FreeType does a `best effort' attempt. However, this value is defined in the PDF and PostScript specs, and that algorithm is better than the one FreeType currently uses: FreeType: Use the middle of the bounding box as the X coordinate of the vertical origin. Adobe PDF spec: Use the middle of the horizontal advance vector as the X coordinate of the vertical origin. FreeType's algorithm goes wrong if you have a really small glyph (like the full-width, circle-like dot at the end of the sentence, as used in CJK scripts) with large bearings. With the FreeType algorithm this dot gets centered on the baseline; with the PDF algorithm it gets the correct location (in the top right). Note that this is a serious issue, it's like printing the dot at the end of a Roman sentence at the center of the textline instead of on the baseline like it should. So i believe the PDF spec's algorithm should be used in FreeType as well. The `vertBearingY' value for such small glyphs is also very strange if no `vmtx' information is present, since the height of the bbox is not representable for the height of the glyph visually (the whitespace up to the baseline is part of the glyph). The fix also includes some code for a better estimate of `vertBearingY'. * src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Estimate for `vertBearingY' now works better for small glyphs completely above or below the baseline into account. * src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now calculated as described by the Adobe PDF Spec. Vertical metrics information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS was not defined. * src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is now calculated as described by the Adobe PDF Spec.

FT_USE_MODULE declares things as: extern const FT_Module_Class (or similar for C++). However, the actual types of the variables being declared are often different, e.g., FT_Driver_ClassRec or FT_Renderer_Class. (Some are, indeed, FT_Module_Class.) This works with most C compilers (since those structs begin with an FT_Module_Class struct), but technically it's undefined behavior. To quote the ISO/IEC 9899:TC2 final committee draft, section 6.2.7 paragraph 2: All declarations that refer to the same object or function shall have compatible type; otherwise, the behavior is undefined. (And they are not compatible types.) Most C compilers don't reject (or even detect!) code which has this issue, but the GCC LTO development branch compiler does. (It outputs the types of the objects while generating .o files, along with a bunch of other information, then compares them when doing the final link-time code generation pass.) Patch from Savannah bug #25133. * src/base/ftinit.c (FT_USE_MODULE): Include variable type. * builds/amiga/include/freetype/config/ftmodule.h, include/freetype/config/ftmodule.h, */module.mk: Updated to declare pass correct types to FT_USE_MODULE.

* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer assume that the first argument on the stack is the bottom-most element. Two reasons: o According to people from Adobe it is missing in the Type 2 specification that pushing of additional, superfluous arguments on the stack is prohibited. o Acroread in general handles fonts differently, namely by popping the number of arguments needed for a particular operand (as a PS interpreter would do). In case of buggy fonts this causes a different interpretation which of the elements on the stack are superfluous and which not. Since there are CFF subfonts (embedded in PDFs) which rely on Acroread's behaviour, FreeType now does the same.

* src/cff/cffobjs.c (cff_face_init): Compute final `dict->units_per_em' value before assigning it to `cffface->units_per_EM'. Otherwise, CFFs without subfonts are be scaled incorrectly if the font matrix is non-standard. This fixes Savannah bug #23630. * docs/CHANGES: Updated.

Finish fix of scaling bug of CID-keyed CFF subfonts. * include/freetype/internal/ftcalc.h, src/base/ftcalc.c (FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled): New functions. * src/cff/cffobjs.h (CFF_Internal): New struct. It is used to provide global hinting data for both the top-font and all subfonts (with proper scaling). * src/cff/cffobjs.c (cff_make_private_dict): New function, using code from `cff_size_init'. (cff_size_init, cff_size_done, cff_size_select, cff_size_request): Use CFF_Internal and handle subfonts. (cff_face_init): Handle top-dict and subfont matrices correctly; apply some heuristic in case of unlikely matrix concatenation results. This has been discussed with people from Adobe (thanks goes mainly to David Lemon) who confirm that the CFF specs are fuzzy and not correct. * src/cff/cffgload.h (cff_decoder_prepare): Add `size' argument. * src/cff/cffgload.c (cff_builder_init): Updated. (cff_decoder_prepare): Handle hints globals for subfonts. Update all callers. (cff_slot_load): Handling scaling of subfonts properly. * src/cff/cffparse.c (cff_parse_fixed_dynamic): New function. (cff_parse_font_matrix): Use it. * src/cff/cfftypes.h (CFF_FontDictRec): Make `units_per_em' FT_ULong. * docs/CHANGES: Document it.

First steps to fix the scaling bug of CID-keyed CFF subfonts, reported by Ding Li on 2008/03/28 on freetype-devel. * src/base/cff/cffparse.c (power_tens): New array. (cff_parse_real): Rewritten to introduce a fourth parameter which returns the `scaling' of the real number so that we have no precision loss. This is not used yet. Update all callers. (cff_parse_fixed_thousand): Replace with... (cff_parse_fixed_scaled): This function. Update all callers.

Fix support for subsetted CID-keyed CFFs. * include/freetype/freetype.h (FT_FACE_FLAG_CID_KEYED, FT_IS_CID_KEYED): New macros. * src/cff/cffobjs.c (cff_face_init): Set number of glyphs to the maximum CID value in CID-keyed CFFs. Handle FT_FACE_FLAG_CID_KEYED flag. * docs/CHANGES: Document it. Fix CFF font matrix calculation and improve precision. * src/cff/cffparse.c (cff_parse_real): Increase precision if integer part is zero. (cff_parse_font_matrix): Simplify computation of `units_per_em'; this prevents overflow also. Support FT_Get_CID_Registry_Ordering_Supplement for PS CID fonts. * src/cid/cidriver.c: Include FT_SERVICE_CID_H. (cid_get_ros): New function. (cid_service_cid_info): New service structure. (cid_services): Register it.

* src/cff/cffparse.c (cff_parse_real): Don't apply `power_ten' division too early; otherwise the most significant digit(s) of the final result are lost as the value is truncated to an integer. This fixes Savannah bug #21794 (where the patch has been posted too).
