Corrects calculation of intermediate buffer width multiplier.
...
Specifically: I had failed to factor in that the multiplied-up input frequency might be less than than the full width of the bitmap.
The Atari and MSX in particular now look much better.

Eliminates attempts cleverly to shuffle unsubmitted runs, because no mechanism exists to stop them overwriting previously-submitted-but-not-yet-flushed runs. Which implies that the buffer must be fully circular. The cost of which is sometimes having to make two calls to glTexSubImage2D. Also added some TODOs, and a means for reporting when a retain_latest is ineffective, in which situation it would be inappropriate to attempt to generate correlated geometry

Ensured the same write area can be submitted multiple times — this is actively used if a run of data overlaps a flywheel-suggested sync. Which nullifies the idea of not having a write area in the barrel, at least as soon as any one has been allocated.

Switched phase and amplitude varying to a 3d vector; the third component is 1/amplitude if amplitude is non-zero, and zero otherwise. So you can multiply by that to get chrominance, rather than dividing by amplitude. With the direct effect that detected chrominance should automatically be zero if the colour burst didn't exist (i.e. had zero amplitude).
