Garret Rieger 9d0b2da51b [repacker] count subtable size in each group of consecutive layers for extension promotion decisions.

- SubTables + Descendants

Garret Rieger b4f561dbbf [subset] Add some comments to find_space_roots/find_32_bit_roots methods. 2022-07-06 18:49:23 +00:00
Garret Rieger 401066bf3d [subset] Prepare the repacker for handling 24bit offsets in GSUB/GPOS.
The boring expansion (https://github.com/be-fonts/boring-expansion-spec) plans to introduce 24bit offsets into GSUB/GPOS. This changes the repacker to treat 24 bit offsets similar to 32 bit offsets and assign the top level 24 bit offsets into spaces to improve packing.
