Switched to using quads for intermediate draws. The specific concern is the flexibility offered in the GL spec as to line drawing algorithms. And even if a driver implements exactly to spec then it should omit the final pixel.

Reduced precision of input phase, but I'm not necessarily persuaded by it as a move. However it's clear that something is off in that whole area. But if phase is locked by output position, do I need to retain this level of complexity? Also ensured that intermediate buffers prior to the final are sampled using the nearest sampling mode, also to reduce precision errors.

Definitively eliminated the additional y filtering step; if I'm going to work to ensure always four samples per colour cycle, I can put the channel separation coefficients directly into their shaders, cutting down on samples.

Restored proper colour separation, but somewhere a massive hit in horizontal resolution is happening — much greater than one would expect from the sample size picked. So investigation to come.

Made an attempt to shuffle the texture builder to a similar flush/submit pattern as the input builder. Don't care about thread safety yet, as it's obvious I'm going to need to move that back up to the CRT.
