Undoes older interpretation of alternating phase.
...
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.

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.
