Behdad Esfahbod e854739b2d [fuzzing] Add test font for previous commit 2022-10-26 13:12:56 -06:00
Garret Rieger db22bfb3cc [subset] Remove Franklin from the tests which is not an open source font. 2022-10-17 13:15:47 -06:00
Garret Rieger 3394ec7048 [subset] use subset accelerator in tests.
This ensures it produces equivalent subsets as without the accelerator.

Qunxin Liu d5fc4a73c0 [instance] add tests for featureVariations
Also updated the script that is used to generate tests.With fonttools,
we now do instancing first and then subsetting.

With different order of subsetting and instancing operations on the same
VF file, fonttools seems to generate 2 different font files with different
glyph set.
1. do subsetting and then instancing: this seems result in a larger glyph
   set in the font file. Lookups are collected from both retained features
   and all possible alternate featurevariations, this leads to a larger
   glyph set after glyph closurei. And instancer doesn't redo glyph
   closure, it does lookups pruning only.

2. do instancing and then subsetting: lookups are collected from
   features that are replaced already and possible alternate feature
   variations

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 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.
