Garret Rieger	a652281ed6	[subset] Fix fuzzer timeout. Fixes https://oss-fuzz.com/testcase-detail/5979721620652032. Timeout was caused by degenerate map insert behaviour due to poor integer hash function. Presize the map to avoid it. Also fixes collect_mapping() for cmap format 13.	1 year ago

Garret Rieger	2175f5d050	[subset] Fix inefficient ItemVariationStore subsetting w/ retain_gids. ItemVariationStore is relying on the assumption that the inner_map is populated for all output glyphs, this is not true for subsetting operations with retain gids enabled.

Garret Rieger	918193ebf9	[subset] fix a class of fuzzer timeouts caused by large shared coverage tables. More acurately estimates the op count for CoverageFormat2 tables as the population size instead of the size in bytes.	2 years ago
Garret Rieger	ddd0f7f40b	[subset] Add a test for CFF2 instancing. Adds option to disable the fonttools comparison check in the test. This is needed since CFF2 instancing is not yet supported in fonttools.	2 years ago

Behdad Esfahbod	64fa5cd482	[GPOS] Fix assert fail introduced recently Was introduced in `8708b9e081`. If these lookups are recursed to from (Chain)Context out-of-order, it was possible that last_base > buffer->idx, in which case we were attaching marks to a base after them... and an assertion was failing fortunately.

Andres Salomon	0bbc9d5256	[fonts] move OFL-1.1 license to a higher directory There's a bunch of font directories inside of test/ for which the vast majority of fonts are licensed under the SIL open font license. We currently have a COPYING file in test/shape/data/in-house/COPYING that says that most of the fonts are OFL-1.1, but that doesn't apply to the fonts in, say, test/api/fonts/ or test/fuzzing/fonts/. Since there are so many OFL-1.1 fonts all over test, let's move the COPYING file to the top-level test/ directory.	2 years ago
Andres Salomon	c622c6b883	[font] update the license url for TestGVAREight.ttf The url in the exif data incorrectly links to a proprietary license. However, permission was granted for distribution under Apache-2 as part of another project, so link to that project's license instead. fixes #4062	2 years ago
