Garret Rieger 3394ec7048 [subset] use subset accelerator in tests. 
This ensures it produces equivalent subsets as without the accelerator.

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.

Khaled Hosny dcd8fe2c3b Revert "[ci] Mark automatic releases as draft" 
This reverts commit 9a28df411e.

It creates a new draft release for each upload, which is not what we are
after.

Garret Rieger 99f4668e19 [repacker] use mutable copies of Coverage/ClassDef in MarkBasePos shrink operation. 
Also make mutable copies (when needed) of the top level subtables during a split operation.

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.

Qunxin Liu e94fe2adf3 [instance] minor optimizations to glyf instancing 2022-09-29 12:14:43 -06:00
Qunxin Liu d5fc4a73c0 [instance] add tests for featureVariations 
Also updated the script that is used to generate tests.With fonttools,
we now do instancing first and then subsetting.

With different order of subsetting and instancing operations on the same
VF file, fonttools seems to generate 2 different font files with different
glyph set.
1. do subsetting and then instancing: this seems result in a larger glyph
   set in the font file. Lookups are collected from both retained features
   and all possible alternate featurevariations, this leads to a larger
   glyph set after glyph closurei. And instancer doesn't redo glyph
   closure, it does lookups pruning only.

2. do instancing and then subsetting: lookups are collected from
   features that are replaced already and possible alternate feature
   variations

Qunxin Liu b90ce34a25 [instance] fix for non-empty .notdef glyph metrics update 
we need pass in source glyph's outline data to calculate boundaries, and
then drop the outline data if notdef-outline is specified.

Also disable shifting points for instancing in get_points () API
