Henrik RydgårdandClaude Opus 5.5 e896203f32 Reinterpret between 16- and 32-bit framebuffers by PSP pixel at higher render scales ...

The 16-to-32-bit reinterpret sampled a quarter texel either side of the
render pixel, which only lands in the two 16-bit halves of a 32-bit pixel at
1x: at 3x, two of every three render pixels took both halves from the same
16-bit pixel. The 32-to-16-bit one picked the half by render pixel too. Now
both go by the PSP pixel. Cars Race-O-Rama rewrites its 8888 frame through
565 views in 16-pixel columns, and drew vertical stripes at 2x and up
(#15914); now it renders like 1x. Nothing changes at 1x.
