1dffbae240 support proposed PaintSweepGradient's angles with +1.0 (180°) bias 
In the upcoming draft of COLR spec, PaintSweepGradient's startAngle/endAngle are encoded with a +1.0 bias to allow for representation of a full +360° positive angle. Normal F2Dot14-fraction-of-half-circle angles can only represent angles between -360 <= angle < +360

This is a breaking change and will need to be coordinated with rendering implementations (at least FreeType/Skia).

82460bd368 otConverters: define a base class for all fixed-size floats with toInt/fromInt methods 
this will be useful when computing deltas for COLR table fields that use Fixed or F2Dot14 (ItemVariationStore internally treats fixed-value floats as 16 or 32-bit integers)

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).

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.
