New minor version.

[Bruce Dubbs]

12.3.0

• Invalid font tables (eg. GSUB/GPOS) are outright rejected, instead of partially validated and used. This behavior is different from DirectWrite and HarfRust, and is in line with CoreText. For context and reasoning see: 5535 (comment)
• Various speed optimizations:
  • AAT shaping: speed up state machine on Apple silicon using a fast-path. 12% faster in LucidaGrande benchmark.
  • OpenType shaping: speed up (Chain)Context lookup shaping using a fast-path and Coverage caching. 20% speedup in NotoNastaliqUrdu benchmark.
  • Drawing mega variable-fonts: 30% speedup on GoogleSansFlex benchmark.
  • Drawing VARC fonts: 5% speedup on varc-hanzi benchmark.
• Always apply synthetic slant around horizontal glyph origin in hb-draw API.
• Fix undefined C++ behavior in some uses of union.
• Remove the disabled by default uniscribe-bug-compatible mode from Indic and Khmer shapers, that used to be used when testing against Uniscribe shaping behaviour.
• Support full instancing fonts with v2 avar table.
• Various subsetting, build, fuzzing, and documentation fixes.
