2f491b5be1
Reintroduces fragment snapping for composite colour sampling.
...
Thereby uncovers some sort of slightly-off recording of scan lines. On the Apple II, individual scans reach the ScanTarget at a density of exactly 0.25 colour cycles per pixel. So that timing information propagates exactly. But the whole lines that are composed via ::announce end up trying to fit 0.250154 colour cycles per pixel. Which creates a phase error as the display progresses from left to right.
This will need to be resolved in order to be able to fix the Apple II's intended colour phase. But, also, it's probably what was wrong with the Oric. And, quite possibly, why the single-step shader didn't work.

For now, just the raw scans, direct to the framebuffer, with no intermediate processing. But it seems to prove that at least some of the proper data is reaching the GPU.

I now understand, hopefully, that it's only the phase of the second colour component that alternates. That has the pointwise effect of reversing the colour signal. Hence the effect of phase errors cancelling themselves out up on successive lines up to a point.
