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).

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

10fe1c2636 Don't write Format for Coverage, ClassDef, Single/Alternate/LigatureSubst 
The format values for those are automatically handled in
postRead/preWrite to choose optimal format.  As such, don't write them
in XML.  Reduces noise.

move PaintFormat enum outside of Paint class nested scope 
When a TTFont is loaded with lazy=True, the otTables are only loaded upon BaseTable.__getattr__
when the requested attribute is not found in the instance __dict__.
Since the Paint.Format enum was defined at class level, every Paint instance, even when loaded
lazily, will have a 'Format' attribute and the magic decompile-on-missing-attribute will not
trigger, since the class attribute will be returned when the instance is missing one.

For this reason, and to not add further special cases, it's better to simply move this Paint.Format
enum class outside to the module level scope, and rename it PaintFormat.

add otConverter for namedtuples and use it for Variable{Scalar,Position,Distance} 
in COLRv1 all scalar values have associated varIdx to support variations. I want to load them as
immutable namedtuples, and also I want to dump them as simple XML tags with 'value' and 'varIdx'
attributes, instead of normal otTables (i.e. with nested Value and VarIdx sub-elements) as
that would make them too verbose in the XML dump.
So I made a custom _NamedTupleConverter, as a base class for VariableScalar, etc.; sub-classes
must provide a tupleClass and a list of converterClasses for each namedtuple field.

The ExtendMode enum has also a custom converter to dump it as string in the XML, and load it
as IntEnum.
