fields.
(af_face_globals_free): Reset new fields.
[autofit] Add stem-darkening properties. Actual code follows in a later commit. * include/freetype/ftautoh.h: Document `no-stem-darkening' and `darkening-parameters'. * src/autofit/afmodule.h: New fields `no_stem_darkening' and `darken_params'. * src/autofit/afmodule.c (af_property_set, af_property_get): Handle them. (af_autofitter_init): Initialize them.

(af_autofitter_init): Initialize them.
[ftfuzzer] Add support for multiple files (patch #8779). Currently, libFuzzer only supports mutation of a single file. We circumvent this problem by using an uncompressed tar archive as multiple-file input for the fuzzer. This patch enables tests of `FT_Attach_Stream' and AFM/PFM parsing; a constructed tarball should contain a font file as the first element, and files to be attached as further elements. * src/tools/ftfuzzer/ftfuzzer.cc: Include libarchive headers. (archive_read_entry_data, parse_data): New functions. (LLVMFuzzerTestOneInput): Updated. * src/tools/ftfuzzer/ftmutator.cc: New file, providing a custom mutator for libFuzzer that can mutate tarballs in a sensible way.

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.

Add another tracing message. (tt_face_load_font_dir): Only allocate table array for valid entries as returned by `check_table_dir'.

[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.
[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.

If a glyph has only one very narrow feature, the bbox can end up with either the width or height of the bbox being 0, in which case no raster memory is allocated and no attempt is made to render the glyph.

[raster] Fix uninitialized memory access. Apparently `ras.cProfile' might be uninitialized. This will be the case if `ras.top == ras.cProfile->offset', as can be seen in `End_Profile'. The overshoot code introduced in a change `Fix B/W rasterization of subglyphs with different drop-out modes.' (from 2009-06-18) violated this, accessing `ras.cProfile->flags' unconditionally just before calling `End_Profile' (which then detected that `cProfile' is uninitialized and didn't touch it).

[base] Do not reorder library->renderers upon use.
Instead of keeping `library->renderers' in a MRU order, just leave
it as-is. The MRU machinery wasn't thread-safe.
With this patch, rasterizing glyphs from different faces from
different threads doesn't fail choosing rasterizer
(FT_Err_Cannot_Render_Glyph).
Easiest to see that crash was to add a `printf' (or otherwise let
thread yield in FT_Throw with debugging enabled).

[raster] Allocate render pool for mono rasterizer on the stack. Instead of using the `render_pool' member of `FT_Library' that is provided down to the rasterizer, completely ignore that and allocate needed objects on the stack instead. With this patch, rasterizing glyphs from different faces from different threads doesn't crash in the monochrome rasterizer. * src/raster/ftraster.c (black_TRaster): Remove `buffer', `buffer_size', and `worker' members. (ft_black_render): Create `buffer' locally. (ft_black_reset): Updated.
