Raph Levien	b2e7c80d3b	Fix non-mac builds ... Also updates comment. We know the implementation is incomplete and needs refinement, but it seems useful to commit as a starting point for further work.	2022-02-07 13:54:24 -08:00
Raph Levien	0cf370f9c7	Mostly working rendering ... This exposes interfaces to render glyphs into a texture atlas. The main changes are: * Methods to plumb raw Metal GPU resources (device, texture, etc) into piet-gpu-hal objects. * A new glyph_render API specialized to rendering glyphs. This is basically the same as just painting to a canvas, but will allow better caching (and has more direct access to fonts, bypassing the Piet font type which is underdeveloped). * Ability to render to A8 target in addition to RGBA. WIP, there are some rough edges, not least of which is that the image format changes are only on mac and cause compile errors elsewhere.	2022-01-19 12:10:51 -08:00
Raph Levien	833d993a4e	More progress exposing interface ... Much of the surface area exists for rendering now. WIP of course still	2022-01-18 18:41:28 -08:00
