Behdad Esfahbod 301f6e4b47 [Coverage] Remove TODO 2022-12-04 11:46:10 -07:00
Behdad Esfahbod dbbb8e8006 Revert "[map] Add hb_map_filter_invalid"
This reverts commit 8d7e921117.

Surprisingly this slowed NotoNastaliqUrdu benchmark down by a couple
percent instead of speeding it up.

Garret Rieger 8f1bf23cc9 [subset] optimize glyf subsetting w/ retain gids.
When retain gids is enabled the subset plan may require the output of many empty glyphs. This change optimizes the glyf subsetting code when the number of retained glyphs << number of output glyphs. Unnessecary lookups to the glyph map are reduced by iterating through the glyph map instead of the output glyph set.

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. :(
