8539915d	2015-10-13T20:43:19	[type1] Correctly handle missing MM axis names (#46202). * src/type1/t1load.c (T1_Get_MM_Var): Implement it.
58b61b6e	2015-10-13T18:26:18	[pcf] Quickly exit if font index < 0. Similar to other font formats, this commit makes the parser no longer check the whole PCF file but only the header and the TOC if we just want to get the number of available faces (and a proper recognition of the font format). * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated. Exit quickly if face_index < 0. * src/pcfread.c (pcf_load_font): Add `face_index' argument. Exit quickly if face_index < 0. * src/pcf/pcf.h: Updated.
bdb56bba	2015-10-13T11:51:13	[ftfuzzer] Handle TTCs and MM/GX variations. This patch also contains various other improvements. * src/tools/ftfuzzer/ftfuzzer.cc: Add preprocessor guard to reject pre-C++11 compilers. (FT_Global): New class. Use it to provide a global constructor and destructor for the `FT_Library' object. (setIntermediateAxis): New function to select an (arbitrary) instance. (LLVMFuzzerTestOneInput): Loop over all faces and named instances. Also call `FT_Set_Char_Size'.
43a96eb2	2015-10-13T11:18:55	[truetype] Refine some GX sanity tests. Use the `gvar' table size instead of the remaining bytes in the stream. * src/truetype/ttgxvar.h (GX_BlendRec): New field `gvar_size'. * src/truetype/ttgxvar.c (ft_var_load_gvar): Set `gvar_size'. (ft_var_readpackedpoints, ft_var_readpackeddeltas: New argument `size'. (tt_face_vary_cvt, TT_Vary_Apply_Glyph_Deltas): Updated.
052f6c56	2015-10-13T08:24:32	[truetype] Another GX sanity test. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Check `tupleCount'. Add tracing message.
7ef0d866	2015-10-13T08:14:20	[truetype] Fix memory leak for broken GX fonts (#46188). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix scope of deallocation.
f96094ee	2015-10-13T07:13:56	[truetype] Fix commit from 2015-10-10. * src/truetype/ttgxvar.c (ft_var_load_gvar): Add missing error handling body to condition.
b9880aa0	2015-10-12T10:13:26	[unix] Make MKDIR_P actually work. * builds/unix/configure.raw: Fix underquoting of `INSTALL' and `MKDIR_P'. Problem reported by Dan Liddell <lddll@yahoo.com>.
4f7f6f6e	2015-10-11T07:55:25	[sfnt] Improve extraction of number of named instances. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Check number of instances against `fvar' table size.

c14ae9c5	2015-10-10T22:28:26	* src/base/ftoutln.c (FT_Outline_Get_Orientation): Fix overflow (#46149).
8de39a79	2015-10-10T13:34:11	[sfnt] Fix infinite loops with broken cmaps (#46167). * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next): Take care of border condidions (i.e., if the loops exit naturally).
da34673e	2015-10-10T10:21:27	[truetype] More sanity tests for GX handling. These tests should mainly help avoid unnecessarily large memory allocations in case of malformed fonts. * src/truetype/ttgxvar.c (ft_var_readpackedpoints, ft_var_readpackeddeltas): Check number of points against stream size. (ft_var_load_avar): Check `pairCount' against table length. (ft_var_load_gvar): Check `globalCoordCount' and `glyphCount' against table length. (tt_face_vary_cvt): Check `tupleCount' and `offsetToData'. Fix trace. (TT_Vary_Apply_Glyph_Deltas): Fix trace. Free `sharedpoints' to avoid memory leak.

d353f6e0	2015-10-10T06:54:46	* src/pcf/pcfread.c (pcf_read_TOC): Check stream size (#46162).
c12956e7	2015-10-09T09:38:32	* src/gzip/ftgzip.c (FT_Stream_OpenGzip): Use real stream size.
d98053c9	2015-10-08T23:17:41	[pcf] Protect against invalid number of TOC entries (#46159). * src/pcf/pcfread.c (pcf_read_TOC): Check number of TOC entries against size of data stream.
06c2d332	2015-10-08T21:31:57	[type42] Protect against invalid number of glyphs (#46159). * src/type42/t42parse.c (t42_parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream.
983b00ec	2015-10-08T18:44:45	[sfnt] Fix some signed overflows (#46149). * src/sfnt/ttsbit.c (tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use `FT_MulDiv'.

dde84f25	2015-10-07T22:18:22	[ftfuzzer] Add support for LLVM's LibFuzzer. * src/tools/ftfuzzer/ftfuzzer.cc, src/tools/runinput.cc: New files.
6eb6158d	2015-10-06T22:39:54	[smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation.
066a4913	2015-10-06T07:55:32	[cff] Return correct PS names from pure CFF (#46130). * src/cff/cffdrivr.c (cff_get_ps_name): Use SFNT service only for SFNT.

b260dc9f	2015-10-04T07:39:22	[bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_input), src/gzip/ftgzip.c (ft_gzip_file_fill_input): In case of an error, adjust the limit to avoid copying uninitialized memory.
53838ce0	2015-10-03T21:12:25	[bzip2, gzip] Avoid access of unitialized memory (#46109). * src/bzip2/ftbzip2.c (ft_bzip2_file_fill_output), src/gzip/ftgzip.c (ft_gzip_file_fill_output): In case of an error, adjust the limit to avoid copying uninitialized memory.
e2dae8fe	2015-10-01T22:03:34	[smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove never used fields.
90e437e3	2015-10-01T20:00:27	[sfnt] Make `tt_cmap4_char_map_linear' more robust (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Take care of border conditions (i.e., if the loop exits naturally).
fab67b85	2015-10-01T16:47:05	* src/autofit/afranges.c (af_deva_nonbase_uniranges): Fix ranges. They should be a subset of `af_deva_uniranges'.
5f8f44d2	2015-10-01T14:16:03	[sfnt] Make `tt_cmap4_char_map_linear' faster (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Use inner loop to reject too large glyph indices.
8bbcfb2c	2015-09-30T23:08:53	[smooth] Clean up worker. * src/smooth/ftgrays.c (gray_TWorker): Remove lightly used `last_ey'. (gray_start_cell, gray_render_line): Update.
dbd04269	2015-09-30T17:52:42	[autofit] Replace `no-base' with `non-base'. * src/autofit/*: Do it.
2ff83a5c	2015-09-30T14:44:29	[sfnt] Rewrite `tt_cmap4_char_map_linear' (#46078). * src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Add code to better skip invalid segments. If searching the next character, provide a more efficient logic to speed up the code.
8651f37a	2015-09-30T10:26:10	[truetype] Adjust number of glyphs for malformed `loca' tables. * src/truetype/ttpload.c (tt_face_load_loca): Implement it.
483007fc	2015-09-29T11:22:15	[pshinter] Avoid harmless overflow (#45984). * src/pshinter/pshglob.c (psh_blues_set_zones): Fix it.

fb5268cf	2015-09-28T02:01:43	[base] Fix a leak by broken sfnt-PS or resource fork (#46028). open_face_from_buffer() frees passed buffer if valid font is not found. But if copying to the buffer is failed, the allocated buffer should be freed within the caller. * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free the buffer `sfnt_ps' if an error caused before calling open_face_from_buffer(). (Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if an error caused before calling open_face_from_buffer();
8a05d250	2015-09-28T01:40:21	[mac] Fix buffer size calculation for LWFN font. * src/base/ftmac.c (read_lwfn): Cast post_size to FT_ULong to prevent confused copy by too large chunk size.
3dffe8ef	2015-09-27T11:30:17	Add ChangeLog entry.
19188a9a	2015-09-26T16:57:17	[autofit] Minor tracing improvement. * src/autofit/aflatin.c (af_latin_metrics_scale_dim): Don't emit blue zones header line if there are no blue zones.
41877539	2015-09-26T15:19:54	[bzip2, gzip, lzw] Harmonize function signatures with prototype. Suggested by Hin-Tak Leung. * src/bzip2/ftbzip2.c (ft_bzip2_stream_io), src/gzip/ftgzip.c (ft_gzip_stream_io), src/lzw/ftlzw.c (ft_lzw_stream_io): Do it.

2439c515	2015-09-25T16:54:28	[type1] Protect against invalid number of glyphs (#46029). * src/type1/t1load.c (parse_charstrings): Check number of `CharStrings' dictionary entries against size of data stream.
5339c75e	2015-09-24T13:39:44	[sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs.
c409eb18	2015-09-24T12:39:38	[base, sfnt] Better checks for invalid cmaps (1/2). * src/base/ftobjs.c (FT_Get_Char_Index): Don't return out-of-bounds glyph indices. (FT_Get_First_Char): Updated. * src/sfnt/ttcmap.c (tt_cmap6_char_next): Don't return character codes greater than 0xFFFF. (tt_cmap8_char_index): Avoid integer overflow in computation of glyph index. (tt_cmap8_char_next): Avoid integer overflows in computation of both next character code and glyph index. (tt_cmap10_char_index): Fix unsigned integer logic. (tt_cmap10_char_next): Avoid integer overflow in computation of next character code. (tt_cmap12_next): Avoid integer overflows in computation of both next character code and glyph index. (tt_cmap12_char_map_binary): Ditto. (tt_cmap12_char_next): Simplify. (tt_cmap13_char_map_binary): Avoid integer overflow in computation of next character code. (tt_cmap13_char_next): Simplify.
e982f5b7	2015-09-21T23:07:22	[base] Check too long POST and sfnt resource (#45919). * src/base/ftbase.h (FT_MAC_RFORK_MAX_LEN): Maximum length of the resource fork for Mac OS. The resource fork larger than 16 MB can be written but could not be handled correctly, at least in Carbon routine. See https://support.microsoft.com/en-us/kb/130437 * src/base/ftobjs.c (Mac_Read_POST_Resource): No need `0x' for `%p' formatter. * src/base/ftbase.c (Mac_Read_POST_Resource): Check the fragment and total size of the concatenated POST resource before buffer allocation. (Mac_Read_sfnt_Resource): Check the declared size of sfnt resource before buffer allocation. * src/base/ftmac.c (read_lwfn, FT_New_Face_From_SFNT): Check the total resource size before buffer allocation.
730b6d74	2015-09-19T12:41:12	[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.
cb7a5122	2015-09-19T07:58:03	[pcf] Improve `FT_ABS' fix from 2015-09-17 (#45999). * src/pcf/pcfread.c (pcf_load_font): Do first the cast to FT_Short, then take the absolute value. Also apply FT_ABS to `height'.
f28c95c4	2015-09-17T19:30:26	[type42] Fix memory leak (#45989). * src/type42/t42parse.c (t42_parse_charstrings): Allow only a single `CharStrings' array.
4942c2bb	2015-09-17T17:56:53	[psaux] Fix memory leak (#45986). * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_MM_BBOX>: Free `temp' in case of error.
7d364b7e	2015-09-17T16:31:58	[psaux] Improve tracing message. * src/psaux/psobjs.c (ps_parser_load_field) <T1_FIELD_TYPE_MM_BBOX>: Handle plural correctly.

9db9adda	2015-09-17T13:42:59	[pcf] Use FT_ABS for some property values (#45893). * src/pcf/pcfread.c (pcf_load_font): Take absolute values for AVERAGE_WIDTH, POINT_SIZE, PIXEL_SIZE, RESOLUTION_X, and RESOLUTION_Y. In tracing mode, add warnings.
bd0438a4	2015-09-16T18:05:43	Minor fixes for some clang warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY): Cast, possible missing initialization. * src/truetype/ttgload.c (TT_Process_Composite_Component): Cast.
19cb1127	2015-09-15T08:52:36	[type1, type42] Fix memory leaks (#45966). * src/type1/t1load.c (parse_blend_axis_types): Handle multiple axis names.

7f0f4011	2015-09-15T07:23:53	[truetype] Fix integer type (#45965). * src/truetype/ttobjs.c (tt_synth_sfnt_checksum): Implement it.
577daf1c	2015-09-15T07:10:16	* src/pcf/pcfread.c (pcf_load_font): Fix integer overflow (#45964).
581c7e2a	2015-09-15T06:49:06	[type1, type42] Check encoding array size (#45961). * src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it.
3ea0d2c6	2015-09-13T23:19:34	* src/base/ftcalc.c (FT_MulFix) [FT_LONG64]: Improve.
7962a15d	2015-09-14T00:38:26	[type1] Fix another potential buffer overflow (#45955). * src/type1/t1parse (T1_Get_Private_Dict): Assure that check for `eexec' doesn't exceed `limit'.
ff7d6404	2015-09-13T23:53:16	Replace `mkinstalldirs' with AC_PROG_MKDIR_P. * builds/unix/mkinstalldirs: Removed, no longer needed. * builds/unix/configure.raw: Call `AC_PROG_MKDIR_P'. Update pwd call for `$INSTALL'. * builds/unix/unix-def.in (MKINSTALLDIRS): Use `@MKDIR_P@'. * autogen.sh: Updated.
3df92aa0	2015-09-13T09:21:52	[winfonts] Check alignment shift count for resource data (#45938). * src/winfonts/winfnt.c (fnt_face_get_dll_font): Implement it.
e3058617	2015-09-13T08:41:43	[type1] Fix potential buffer overflow (#45923). * src/type1/t1parse.c (T1_Get_Private_Dict): Assure `cur' doesn't point to end of file buffer.
e40e8b33	2015-09-13T08:05:50	[gzip] Fix access of small compressed files (#45937). * src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak. (ft_gzip_get_uncompressed_file): Correct byte order while reading unsigned long value. Without this change, the whole optimization of accessing small files in `FT_Stream_OpenGzip' is never executed! As a consequence, access to PCF files in general (which are normally small files) should be much improved now as originally intended.
db5a4a9a	2015-09-12T08:32:55	[psaux] Fix potential buffer overflow (#45922). * src/psaux/psobjs.c (ps_parser_skip_PS_token): If a token is enclosed in balanced expressions, ensure that the cursor position doesn't get larger than the current limit.
19b82cfb	2015-09-11T20:25:32	[base] Avoid crash while tracing `load_mac_face'. Reported in Savannah bug #45919. * src/base/ftobjs.c (load_mac_face): Honour FT_OPEN_MEMORY while tracing.
23423bc6	2015-09-11T08:28:27	[type42] Fix endless loop (#45920). * src/type42/t42parse.c (t42_parse_encoding): Synchronize with type1's `parse_encoding'.
e5a27a75	2015-09-10T07:44:11	[docmaker] Allow `-' in bold and italic markup. * src/tools/docmaker/sources.py (re_italic, re_bold): Adjust accordingly.
09948e42	2015-09-09T21:30:15	* src/base/ftcalc.c (FT_RoundFix): Improve.
822acb02	2015-09-09T07:59:10	* src/base/ftcalc.c (FT_CeilFix, FT_FloorFix): Normalize. This commit makes the functions behave as expected, this is, rounding towards plus or minus infinity.
b002f688	2015-09-07T13:47:36	* src/smooth/ftgrays.c (gray_render_line): Simplify clipping.
5a6dc872	2015-09-04T23:14:46	[raster,smooth] Microoptimizations. * src/raster/ftraster.c (Insert_Y_Turn, Finalize_Profile_Table, Beziier_Up, ): Use do-while loops. * src/smooth/ftgrays.c (gray_render_scanline, gray_render_line, gray_convert_glyph): Ditto.
d3cba0ed	2015-09-04T10:28:53	[autofit] Redesign code ranges (2/2). This commit adds two fallback scripts (`latb', `latp') and implements support for the no-base character ranges introduced in the previous commit. * src/autofit/aftypes.h (AF_ScriptClassRec): Add `script_uni_nobase_ranges' field. (AF_DEFINE_SCRIPT_CLASS): Updated. * src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and `latp' fallback scripts. * src/autofit/afblue.dat: Add blue zones for Latin subscript and superscript fallback scripts. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated. * src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base characters. (AF_STYLE_MASK): Updated. * src/autofit/afglobal.c (SCRIPT): Updated. (af_face_globals_compute_style_coverage): Handle new style flag. * src/autofit/aflatin.c (af_latin_hints_apply): Handle new style flag. * src/autofit/afranges.h (SCRIPT): Use it to export no-base ranges.
696b7126	2015-09-04T10:10:59	[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays.

14d6b5d7	2015-08-13T15:22:17	[truetype] Introduce named instance access to GX fonts. For functions querying a face, bits 16-30 of the face index can hold the named instance index if we have a GX font. The indices start with value 1; value 0 indicates font access without GX variation data. * include/freetype/freetype.h (FT_FaceRec): Update documentation. * include/freetype/internal/sfnt.h: Ditto. * src/sfnt/sfobjs.c (sfnt_init_face) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and do argument checks.

7ebe6ac8	2015-08-11T06:47:25	[builds/unix] Minor. * builds/unix/configure.raw: s/lib{priv,staticconf}/libs{priv,staticconf}/ for orthogonality with similarly named uppercase variables.
a37da21a	2015-08-10T23:05:02	[type1,cid,type42] Minor improvements. * src/type1/t1load.c (t1_parse_font_matrix): Scale units per EM only when necessary. Refresh comments. * src/cid/cidload.c (cid_parse_font_matrix): Ditto. * src/type42/t42parse.c (t42_parse_font_matrix): Refresh comments.
bd75a517	2015-08-08T08:39:45	[type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.
e5f44693	2015-08-08T07:45:03	[type42] Minor clean-up. * src/type42/t42parse.c (t42_parse_font_matrix): Remove unused variable.
fd70512e	2015-08-06T21:49:08	[type42] Parse FontMatrix according to specifications. * src/type42/t42parse.c (t42_parse_font_matrix): Type 42 FontMatrix does not need scaling by 1000. Units_per_EM are taken from the embedded TrueType.
ff406e2e	2015-08-06T07:34:50	[autofit] Improve Arabic hinting. Problem reported by Titus Nemeth <tn@tntypography.eu> (by using ttfautohint). * src/autofit/afblue.dat: Add neutral blue zone for the tatweel character. * src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
98e8e999	2015-08-06T00:06:14	[truetype] Clean up types. * src/truetype/ttobjs.c (TT_Size): Move declaration from here. * include/freetype/internal/tttypes.h (TT_Size): ... to here. (TT_LoaderRec): Switch to appropriate types for `face' and `size'. * src/truetype/ttgload.c: Remove corresponding type casts. * src/truetype/ttsubpix.c: Ditto.
15e2a4f7	2015-08-05T21:53:50	[autofit] Improve recognition of flat vs. rounded segments. Lower the flatness threshold from upem/8 to upem/14, making the auto-hinter accept shorter elements. Synchronize flat/round stem selection algorithm with blue zone code. * src/autofit/aflatin.c (FLAT_THRESHOLD): New macro. (af_latin_metrics_init_blues): Use it. (af_latin_hints_compute_segments): Collect information on maximum and minimum coordinates of `on' points; use this to add a constraint for the flat/round decision similar to `af_latin_metrics_init_blues'.
eb22ef26	2015-08-04T06:50:04	Another left-shift bug (#45681). * src/base/ftobjs.c (IsMacBinary): Only accept positive values for `dlen'.

[pcf] Quickly exit if font index < 0. Similar to other font formats, this commit makes the parser no longer check the whole PCF file but only the header and the TOC if we just want to get the number of available faces (and a proper recognition of the font format). * src/pcf/pcfdrivr.c (PCF_Face_Init): Updated. Exit quickly if face_index < 0. * src/pcfread.c (pcf_load_font): Add `face_index' argument. Exit quickly if face_index < 0. * src/pcf/pcf.h: Updated.

2015-10-06T22:39:54

[smooth] Faster alternative line renderer. This implementation renders the entire line segment at once without subdividing it into scanlines. The main speed improvement comes from reducing the number of divisions to just two per line segment, which is a bare minimum to calculate cell coverage in a smooth rasterizer. Notably, the progression from cell to cell does not itself require any divisions at all. The speed improvement is more noticeable at larger sizes. * src/smooth/ftgrays.c (gray_render_line): New implementation.

[base] Fix a leak by broken sfnt-PS or resource fork (#46028). open_face_from_buffer() frees passed buffer if valid font is not found. But if copying to the buffer is failed, the allocated buffer should be freed within the caller. * src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free the buffer `sfnt_ps' if an error caused before calling open_face_from_buffer().

[sfnt] Better checks for invalid cmaps (2/2) (#46019). While the current code in `FT_Get_Next_Char' correctly rejects out-of-bounds glyph indices, it can be extremely slow for malformed cmaps that use 32bit values. This commit tries to improve that. * src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next, tt_cmap12_char_map_binary, tt_cmap13_next, tt_cmap13_char_map_binary): Reject glyph indices larger than or equal to the number of glyphs.

[sfnt] Improve handling of invalid SFNT table entries (#45987). This patch fixes weaknesses in function `tt_face_load_font_dir'. - It incorrectly assumed that valid tables are always at the beginning. As a consequence, some valid tables after invalid entries (which are ignored) were never seen. - Duplicate table entries (this is, having the same tag) were not rejected. - The number of valid tables was sometimes too large, leading to access of invalid tables. * src/sfnt/ttload.c (check_table_dir): Add argument to return number of valid tables. Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'. Reject duplicate tables and adjust number of valid tables accordingly.

[autofit] Redesign code ranges (1/2). This patch introduces auxiliary code ranges that identify no-base characters; they refer to glyphs of a script that should be hinted without alignments to blue zones (mostly diacritics). It also splits off ranges for fallback scripts that handle subscript and superscript characters not covered by OpenType features. For example, this greatly helps improve the hinting of various phonetic alphabets, which contain a large amount characters that look like superscript glyphs. Finally, code ranges are updated to Unicode 8.0, and enclosed characters are removed in general since they normally look better if they stay unhinted. * src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode 8.0. Split off superscript-like and subscript-like glyphs into... (af_latb_uniranges, af_latp_uniranges): ... these two new arrays. (af_xxxx_nobase_uniranges): New arrays that hold no-base characters of the corresponding character ranges.

[type42] Fix glyph access. This is a severe bug: We've missed one level of indirection, as described in the Type 42 specification. As a result, ftview sometimes showed incorrect glyphs for given glyph names, and even displayed `error 0x0006' (invalid argument!) in case the number of glyph indices differed between the Type 42 font and the embedded TTF. Apparently, noone ever noticed it; this shows how much Type 42 fonts are in use... * src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index to embedded TTF's glyph index.
