Garret Rieger 7cb36e4222 [subset] Re-introduce size threshold in choosing unicode collection method. 
Threshold is needed since the unicodes set might be an inverted set.

Garret Rieger 42c54eba83 [subset] Presize unicode to gid list to unicodes + glyphs size. 2022-05-04 20:21:43 +00:00
Garret Rieger 7c7c01d28c [subset] Remove switch to alternate unicode collection at large subset sizes. 
Benchmarks show that the first path is always faster even at large subset sizes:
