29a2ebf813 omit default VarIndexBase 
4294967295 (0xFFFFFFFF in decimal form) is not very memorable.
Still, using hex notation for all VarIndexBases would make the non-default values less readable (when interpreted as an index into the DeltaSetIndexMap array, decimal makes more sense).
Since 0xFFFFFFFF means 'no variation data', it makes sense to omit it from the ttx dump and write an empty <VarIndexBase/> element with no value.
We also allow to build Var tables without needing to pass "VarIndexBase": 0xFFFFFFFF in the source dict.

a0bd872f0e TupleVariation: make shared tuples order deterministic 
most frequent first (like before https://github.com/fonttools/fonttools/pull/2351), only sort ties alphabetically
 2021-07-02 12:52:54 +01:00
Garret Rieger
7f9e2c3808 sort shared tuples produced by Counter.most_common() 
In python 3.7 and earlier most_common() sorts first by the item count and then arbitrarily in the event of ties. This can result in two identical instancing operations producing different binary results.

d0d59d2f2c Add PaintScale* and Paint{Rotate,Skew}* variants 
This updates fonttools to match the latest draft COLRv1 spec at https://github.com/googlefonts/colr-gradients-spec/pull/290

Summary of changes:
- Added 8 new PaintScale* tables: with/without centers, uniform vs non-uniform
- Added *AroundCenter variants to PaintRotate and PaintSkew (default versions no longer have centerX/Y defaulting to origin)
- PaintRotate, PaintSkew and PaintComposite formats re-numbered

1cb7e36bbd COLRv1: rename otData structs to remove 'V1' to match updated draft spec 
This is a breaking change (but the COLRv1 API was already marked as unstable and subject to change)

The changes in this PR are meant to match the changes from the COLRv1 draft spec at:

e13b781526 removeOverlaps: print glyph name when pathops.simplify fails 
Sometimes skia-pathops simplify may fail (for unknown reasons which I'm still trying to debug).
It's a good idea to know the name of the offending glyph
