Behdad Esfahbod 0a42410dc8 [cff2] Change extents/shape stack to be just a number 
Do the blending immediately.

Fixes https://github.com/harfbuzz/harfbuzz/issues/3559

Benchmark on AdobeVFPrototype shows 35% speedup. Now we're faster
than FreeType:

Behdad Esfahbod ac1bb3e39e [machinery] Move accelerators to constructor/destructor 2022-01-20 12:10:05 -07:00
Behdad Esfahbod e062376ef1 [machinery] Make accelerator lazy-loader call Xinit/Xfini 
Instead of init/fini. To isolate those functions. To be turned into
constructor/destructors, ideally one per commit (after some SFINAE
foo.)
