Behdad Esfahbod 9eab3ac72d [CoverageFormat2] Remove hand-written loop
While on a fuzzer-found test case (added) that loop was faster,
on real fonts, including NotoNastaliq in our benchmark, it was
actually slower, which intuitively I would have expected.

Still no idea why on that fuzzer case it's faster though. :(

Frédéric Wang 03d2376745 [math] Improve fuzzing coverage
Extend testing to cover parts that are missing according to the recent
oss-fuzz-coverage report:
- Retriving all constants from MathConstants.
- Retrieving entries from MathKern, MathGlyphPartRecord and
  MathGlyphAssembly.
- Retrieving italic correction from MathGlyphAssembly.
- Choosing between horizontal/vertical offset in MathVariants.

Khaled Hosny dfc5e5a27d [test] Skip glyph positions for test failing on CI

Khaled Hosny 189e8c326e [ft] Remap legacy Arabic PUA codepoints

Khaled Hosny c3f590bb1e [arabic] Support legacy PUA shaping
Support legacy pre-OpenType Windows 3.1-era fonts, by remapping PUA code
points in cmap table and letting our fallback shaper build the GSUB
table.

Uniscribe applies also mset-like substitution, but our fallback mark
positioning gives better results, so this is not implemented.

Garret Rieger af74ab452f [repack] always run the sort in repack.
This is needed to ensure virtual link ordering constraints are respected when repack is being called from fontTools. For subset usage, repack won't be called if the graph doesn't already overflow so this change doesn't cause any extra work.
