971043374e instancer: add --ignore-overlap-errors option 
This is to be able to ignore tricky glyphs that sometimes trip up Skia PathOps.Simplify operation.
We have no idea how to fix this upstream (short of having the glyphs redrawn), and perfect is the enemy of good..

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.

bba5e8b213 Add optional compaction of GPOS PairPos subtables in otlLib.optimize.gpos 
See pull request: https://github.com/fonttools/fonttools/pull/2326

The new module `otlLib.optimize.gpos` provides `compact` functions that
can reduce the file size of GPOS PairPos lookups by splitting subtables
in a smart way to avoid storing zero-valued pairs.

The compaction methods are called from `otlLib.builder` and
`varLib.merger` so that static and variable fonts can benefit from the
optimization at compile time.

The new module `otlLib.optimize` is also executable, to allow running
the optimization on existing fonts.

The optimization is a trade-off because on the one hand it can reduce
significantly the byte size of the GPOS table (up to 50% in random
Google Fonts) but on the other hand it adds to the compilation time and
may make fonts very slightly bigger once compressed to WOFF2 (because
WOFF2 doesn't mind about zero values and compresses them very well).

As such, the optimization is off by default, and you can activate it by
providing the environment variable `FONTTOOLS_GPOS_COMPACT_MODE=5` for
example (values from 0 = off to 9 = max file size savings, but many more
subtables).
