Garret Rieger 9559d3c1c1 [repacker] fix incorrect coverage table size estimation. 
During splitting of PairPosFormat2 the code was assuming the maximum size of the generated coverage table would be equal too the current size. This is incorrect size the new coverage table may not preserve the ranges found in the original coverage table (since we are splitting based on class, not coverage) and in the worst case may convert from format2 to format1. So use the size of a format1 table as the max size.

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 8fb7cc1c63 [iter] Use && in is_sink_of uses 2022-08-05 11:49:29 -06:00
Garret Rieger 5d824c09c0 [repacker] during table splits don't mutate shared coverage/classdef in place. 
If other subtables are sharing coverage with a subtable being split we have to duplicate the coverage/classdef tables before they are modified during the shrink operation.

hb_pair was causing corrupted gid values.

Garret Rieger fdd1952c75 [repacker] PairPosFormat2 splitting - fix coverage and classdef splitting. 
The old code was splitting based on coverage index, but should have been splitting on class value.

Garret Rieger 60d6ffb375 [repacker] always duplicate classDef2 when splitting a PairPos2. 
Splits are done in a way that it shouldn't be possible to share the classDef2 between split PairPos2's so pre-emptively duplicate it.
