232b2ccbc4 Move the rest of py23 module to textTools 
Change all imports to use textTools module, except the test_py23.py test
which is kept until we decide to remove the module (if ever).

99743c14df subset: explicitly subset ClipList, avoids warning when lazy-loading 
relying on ClipList.compile to drop unused clips based on updated glyphOrder won't work when font is loaded lazily (default for subsetter), because ClipList gets decompiled too late (after glyphOrder has already been modified) and this produces warnings about missing glyphIDs.
Better to make the subsetter explicilty prune unused clips.

000bf81700 Default to "\n" for newlinestr instead of None 
If newlinestr is None, os.linesep is used, bu it is the third millennium
and we don’t need or want different line endings per-platform.

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

2861d65e56 [subset] Update font extents in head table 
When --recalc-bounds option is used the font extents in the head table
need to be updated, but since tables are lazy-loaded by default the
table will not be recompiled and will keep the old value. Force
recompiling the table by adding it to prune_post_subset tables, though
I’m not 100% sure this is the best approach.
