the SFNTReader expects the input file to be seekable, and it already rewinds the file with file.seek(0) to get to the sfnt table directory. Thus, if TTFont is loaded with an unseekable file object and lazy=True, we raise a TTLibError requiring one to either pass a seekable input file, or to not set lazy=True (in which case the input is loaded in a seekable BytesIO)
Fixes https://github.com/fonttools/fonttools/issues/3052
- 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
Make lazy=False actually do what it says, 'load everything eagerly'. It feels weird that one has to, not only say, open with lazy=False, but also have to load each tables individually... Didn't I say don't be lazy?!
Also it can be useful to get to a eager, non-lazy font whether or not it was originally loaded lazily, so I added an ensureDecompiled method that decompiles all the tables and calls ensureDecompiled for those (e.g. cmap, glyf and otData-driven tables like GSUB, GPOS, etc.) that respect the lazy attribute.
