af6804bed5 make USE_HARFBUZZ_REPACKER a 3-state option, defaults to auto 
if explicitly enabled, it will raise ImportError if uharfbuzz is not found, and will propagate the uharfbuzz error instead of silently falling back to the pure-python serializer

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
