Cache CTFont handles on macOS #472

Closed jpochyla closed 2 years ago

jpochyla commented 2 years ago

This implements caching of CTFont handles, not unlike the current font-family cache. This solves a real bottleneck I have in Psst (where creating lot of labels used to be really slow). I've used the associative-cache crate, because it is used in the Direct2D backend already (for caching gradients), and also switched the font family cache to it, for consistency.

Thanks!

I've added the alias and decreased cache size to 64 for both font-families and ctfonts.
