atirage: Implement source rectangle blitting#193
Merged
Conversation
Implement the accelerated same-format source-copy operation (used by the Mac OS X Public Beta when dragging windows). Supports raw 8, 15, 16, and 32 bpp copies. Rejects unsupported mixes, format conversions, partial write masks, color comparison, and source trajectory modes.
Happened to notice that we were not marking the framebuffer as dirty when doing this update. Liekly not an issue in practice since there are usually other updates, but might as well be correct.
