FA-10648 / Raster clipping / Member archive
Clipped blit source offset · case 03
Clamping the destination origin shifts discarded source pixels back into view.
Case contract
Blit source row at signed destination x, discarding out-of-range destination pixels while retaining original source alignment.
Why this case matters
A deterministic software graphics stage with explicit channel and coordinate conventions; no hardware, device profile or API behavior is inferred.
One recorded failure
