[paint] Optimize PAINT_COMPOSITE
...
At the start of each paint call the current group is clear.
So we don't need to start a new group for the backdrop paint.
A paint composite really needs one group push, not two.

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.

[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. :(

It was wrong, because it would be writing wrong values.
