The existing code doesn't correctly handle the case where palettes partially overlap in the color record array.

Partially overlapping palettes will be converted to disjoint segments in the color record array.
Updates one of the color tests to use multiple palettes.

[Boring Expansion] >64k loca & hmtx tables
This does two things:
The num-glyphs reported by the face now is the maximum reported by the maxp and that deduced from the length of the loca table; I think this is the right thing to do anyway; According to OpenType such loca tables are invalid.
The interpretation hmtx tables that have excessive bytes at the end, again, invalid according to OpenType, has changed. Previously we were interpreting those excessive bytes as extra lsb values. Now we interpret them as extra advance values, the last of which is repeated for all missing glyphs. Again, these are tables that are invalid according to OpenType, and the advances are for glyph indices beyond maxp table's num-glyphs.
The combined effect is that the font can have shapes and advances for gid's beyond the maxp limit of 64k. In fact, maxp table becomes optional.
