Gleb Mazovetskiy	3f0d089928	Blitter: Minor optimization `src < end - 3` is one more instruction than `src + 3 < end`. Godbolt: https://godbolt.org/z/PPfhYYWG8 RG-99 binary becomes 224 bytes smaller.	3 years ago
Gleb Mazovetskiy	774993c6d0	dun_renderer: Avoid calling 0-width `Blit*` A slight optimization to avoid calling blit functions entirely when the width is zero.	3 years ago
Gleb Mazovetskiy	397529bf0f	Rendering: Unify and optimize pixel blitters 1. Unifies the underlying CLX and dun_render blitters. 2. Optimizes them by unrolling loops and using pointer comparison rather than length comparison (saves a length decrement). 3. In `dun_render`, extracts `RenderLineTransparent/Opaque` branches into functions via explicit template specialization. Example RG-99 FPS (non-PGO'd): 17.4->18.4	3 years ago
Gleb Mazovetskiy	961866e1c4	CLX: A new graphics format The format is almost identical to CL2, except it uses the frame header to store frame width and height instead of 5 32-line offsets. This means we always have access to frame dimensions, so we can use it as an on-disk format for our graphics as well. Additionally, we may be able to optimize the rendering even more in the future now that we have guaranteed knowledge of frame dimensions.	4 years ago
