Behdad Esfahbod	32c85b8c8c	[avar2] Fix mapping when coords length don't match Ouch. Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=49407	2 years ago
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. :(	2 years ago
Behdad Esfahbod	3c84aa8416	[cff] Add a max work counter Set to 10,000 per interpretation right now. Fixes https://github.com/harfbuzz/harfbuzz/issues/3700 Fixes https://oss-fuzz.com/testcase-detail/5667125715927040	2 years ago

Behdad Esfahbod	5a058ba158	[shape-fuzzer] Add commented out more buffer-verify option Those currently fail and I've been unable to debug them. I tried two, passing them to hb-shape doesn't reproduce the failure. :(	2 years ago
Behdad Esfahbod	189f65344a	[fuzz-shape] Verify shape output Let the fuzzers loose on shape verify.	2 years ago
Garret Rieger	8f9f0c494b	[subset] Enforce cmap12 group ordering constraints in collect_mapping. Fixes fuzzer issue: https://oss-fuzz.com/testcase-detail/6365271012540416	2 years ago
Garret Rieger	b051f3fa83	[subset] Fix cpal subsetting when there are partial palette overlaps. The existing code doesn't correctly handle the case where palettes partially overlap in the color record array. This changes the subsetting to only share entries in the color record array when palettes have the same first color index. Partially overlapping palettes will be converted to disjoint segments in the color record array. Updates one of the color tests to use multiple palettes. Also fixes fuzzer: https://oss-fuzz.com/testcase-detail/5568200165687296.	2 years ago

Behdad Esfahbod	1740916ede	[draw] Remove check for no-op This is unnecessary overhead. Up to rasterizers to handle this. Plus, this throws off point-numbers in uses that rely on it. Disabled one test that broke with this.	3 years ago
