Some SVG authoring tool write arc commands without any space or comma around the boolean 'large-arc' and 'sweep' flags, leading our svg path parser to choke.
This makes the path parser smarter by special-casing arc command parsing so that it only consumes one character ('0' or '1') for these special boolean flags.

LayerV1Record and Affine2x2 are gone.
LayerV1List now contains a list of Paint DAGs
Added 4 new Paint formats: PaintGlyph, PaintColorGlyph, PaintTransform
and PaintComposite
* Add designspace lib key to specify a custom feature tag for feature variations, as discussed in #2079
* Added comment for the lib key
* if the lib key is present, the 'processing' flag should be ignored completely
* Add custom table packer/unpacker registry
* fix documentation for getTableClass(): it will never return None
* add unregisterCustomTableClass(), mostly for testing
This reverts commit 690080b14d9a4f193092ffc172a39b3e212d307c.
We keep 16-bit GlyphIDs for COLRv1 tables, at least for now
https://github.com/googlefonts/colr-gradients-spec/pull/24
I keep the GlyphID32 converter in case we may need it in the future.
Currently unused but will be super helpful for optimizing the formats of contextual lookups.
* Splits the rules of a class contextual lookup based on explicit subtable breaks
* Returns various properties on the ruleset to help determine appropriate layout format.
* (More properties, such as "touched glyphs", planned - will be added when needed.)
Document otlLib
Includes other minor changes:
* When a markFilterSet parameter is passed to a builder, LOOKUP_FLAG_USE_MARK_FILTERING_SET will be added to the lookup's flags.
* The unused arguments valueformat1 and valueformat2 were removed from ClassPairPosSubtableBuilder.
