Problem reported by Akiem Helmling <akiem@underware.nl> and analyzed by Behdad. * src/truetype/ttgxvar.c (ft_var_readpackeddelta): Return deltas in 16.16 format.

Collect deltas in `point_deltas_x' and `point_deltas_y', which are 16.16 format arrays, and add the accumulated values to the glyph coordinates at the end of the function.

[sfnt] Preliminary support of coloured layer outlines. This commit enables OpenType's COLR/CPAL table handling; a typical application are color emojis that can be scaled to any size. If the color palette does not exist or is invalid, the rendering step rasterizes the outline instead. The current implementation assumes that the foreground is black. Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.

Further fix to visibility flag testing with Solaris Studio compilers. AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The Solaris Studio 12.1 through 12.5 compilers see the `-fvisibility=hidden' flag, but ignore it with a warning of: cc: Warning: Option -fvisibility=hidden passed to ld, if ld is invoked, ignored otherwise AC_LINK_IFELSE does the compile and then tries to link the result, at which point the Solaris linker will issue an error: ld: fatal: option '-fvisibility=hidden' is incompatible with building a dynamic executable If we don't use AC_LINK_IFELSE to catch the error, then configure will fail further tests which attempt to link, such as those testing dependencies like `libbz2'. Also, don't try adding `-fvisibility' if we have already added `-xldscope', just use one of them, since Sun Studio 12 and earlier compilers only issue a warning, and don't try passing through to the linker to generate an error, so AC_LINK_IFELSE doesn't catch them. Tested on Solaris 11.4 beta with compiler versions: Sun Studio 8 (Sun C 5.5) Sun Studio 10 (Sun C 5.7) Sun Studio 11 (Sun C 5.8) Sun Studio 12 (Sun C 5.9) Sun Studio 12.1 (Sun C 5.10) Oracle Solaris Studio 12.2 (Sun C 5.11) Oracle Solaris Studio 12.3 (Sun C 5.12) Oracle Solaris Studio 12.4 (Sun C 5.13) Oracle Developer Studio 12.5 (Sun C 5.14) Oracle Developer Studio 12.6 (Sun C 5.15) gcc 5.5.0 gcc 7.3.0 and verified the libfreetype.so.6 generated by each of those compilers exported the same set of symbols. * builds/unix/configure.raw: Implement it.

Fix DLL compilation on Solaris.
AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'. The
Solaris Studio 12.1 through 12.5 compilers see the
`-fvisibility=hidden' flag, but ignore it with a warning of:
cc: Warning: Option -fvisibility=hidden passed to ld,
if ld is invoked, ignored otherwise
AC_LINK_IFELSE does the compile and then tries to link the result,
at which point the Solaris linker will issue an error:
ld: fatal: option '-fvisibility=hidden' is incompatible with
building a dynamic executable
If we don't use AC_LINK_IFELSE to catch the error, then configure
will fail further tests which attempt to link, such as those testing
dependencies like `libbz2'.
Also, don't try adding `-fvisibility' if we have already added
`-xldscope', just use one of them, since Sun Studio 12 and earlier
compilers only issue a warning, and don't try passing through to the
linker to generate an error, so AC_LINK_IFELSE doesn't catch them.
Tested on Solaris 11.4 beta with compiler versions:
Sun Studio 8 (Sun C 5.5)
Sun Studio 10 (Sun C 5.7)
Sun Studio 11 (Sun C 5.8)
Sun Studio 12 (Sun C 5.9)
Sun Studio 12.1 (Sun C 5.10)
Oracle Solaris Studio 12.2 (Sun C 5.11)
Oracle Solaris Studio 12.3 (Sun C 5.12)
Oracle Solaris Studio 12.4 (Sun C 5.13)
Oracle Developer Studio 12.5 (Sun C 5.14)
Oracle Developer Studio 12.6 (Sun C 5.15)
gcc 5.5.0
gcc 7.3.0
and verified the libfreetype.so.6 generated by each of those
compilers exported the same set of symbols.

[sfnt] Fix charmap type 2 iterator (#52646). The subsetted demo font of the report that exhibits the bug has a very unusual type 2 cmap for Unicode(!): It contains only two sub-headers, one for one-byte characters (covering the range 0x20 to 0xFA), and a second one for higher byte 0x01 (just for character code U+0131). Before this commit, the iterator wasn't able to correctly handle a sub-header for higher byte 0x01. * src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment for outer loop.

* include/freetype/ftrender.h: Fix `FT_Renderer_RenderFunc' type.
Use Adobe hinting engine for `light' hinting of both CFF and Type 1. Since Ewald Hew factored the Adobe hinting engine out of the CFF driver code, we can now use it on Type 1 (and CID) font formats, as both have the same hinting philosophy. This change activates the Adobe hinter when in LIGHT mode, and therefore always unless explicitly asking for the auto-hinter. This makes LIGHT behavior consistent with CFF fonts. As of this commit, the hinting engine table looks as follows. LIGHT NORMAL ------------------------- TrueType Auto v40 CFF Adobe Adobe Type 1 Adobe Adobe

[psaux] Fix PostScript interpreter rewinding in Type 1 mode. (#52251) The interpreter in Type 1 mode rewinds the charstring after collecting all hints for building the initial hintmap (commit d52dd7f).

Fixes for rendering. The Type 1 advance width calculation passes null for glyph slot, etc, which can cause null pointer access in the new interpreter. Fall back to the old one for now. Fix the large glyph retry code and ensure hinting and scaling flags are set properly. * src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Add a check for metrics_only.

[cff] Fix family name logic of pure CFF fontdata (#52056). 1. If `FamilyName' is present in the CFF font, use this for FT_Face's `family_name'. 2. Otherwise, use the face name and chop off any subset prefix. 3. If at this point FT_Face's `family_name' is set, use this together with the full name to determine the style. 4. Otherwise, use `CIDFontName' as FT_Face's `family_name'. 5. If we don't have a valid style, use "Regular". Previously, FT_Face's `family_name' entry for pure CFF fontdata nearly always was the fontname itself, instead of the `FamilyName' entry in the CFF font (assuming there is one). * src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
