Optimize Linux GTK dirty pixel conversion - #434
Merged
Merged
Conversation
Linux GTK now uses retained damage metadata to limit RGBA8-to-premultiplied-ARGB32 conversion to affected device pixels. First presentations, resized or reallocated buffers, and invalid damage inputs retain the full-conversion fallback, while valid rectangles are normalized, scaled, rounded outward, and clipped safely. A GTK-independent pixel helper and focused C regression suite cover conversion correctness, stride padding, buffer reuse, edge cases, and preservation of untouched pixels; the focused step is also wired into `zig build test`.
