fef9e9a071 Fix handling of unbounded conditions 
For unbounded conditions, the previous code expects "minimum" or
"maximum" to be entirely absent, whereas actually they will be
consistently present with one having a value of None.

This means that math.inf and -math.inf are never substituted in for the
absent bound, and a crash occurs when the None value propagates.

This commit corrects the behaviour by checking for a value of None,
instead of checking for the presence of the keys, bringing the
behaviour inline with the rest of the library.

d1ec8e6979 Test that DS5 splitting code handles unbounded conditions gracefully 
Conditions with unbounded values have a "minimum" or "maximum" value of
None.

These tests check that:
a) The public-facing split functions can receive None values without
     crashing; and
b) That their internal helper functions correctly translate the None
     values to math.inf and -math.inf to express them.

These tests are expected to fail, indicating where a fix is required.

36de9df3cc [gvar] be non lazy for TTFont.lazy=False, add ensureDecompiled 
like cmap, or glyf or OTL tables, we need to respect lazy=False flag and decompile everything upfront, also we want to add an ensureDecompiled method (called by TTFont.ensureDecompiled) to allow loading everything in one go even when a font had been opened lazily.

b818e1494f Refactor ttGlyphSet.py 
- only differentiate between glyf and CFF/CFF2 implementations, not var vs non-var
- use collections.abc.Mapping to get a more consistent dict-like object with less code
- prefer HVAR metrics over gvar metrics
- move some responsibilities from the _TTGlyphSet objects to the _TTGlyph objects
- adjust some tests to the changes
