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.

Fixed: colour_cycle_numerator_ doesn't need to be multiplied by the time multiplier because it'll get that for free from the calculation of next_run_length.

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.

The "MFM...Byte"s aren't MFM-specific, they're relevant to both FM and MFM encoding. So renamed them. Also slimmed syntax within MFM.cpp mostly where emigration from the Acorn disk analyser had left a residue of lengthy namespace specification.
