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.

Upped intermediate buffer size, at least temporarily, while I look for the source of the interference patterns I'm seeing.

Demonstrated that issue is coloured borders, made a guess as to buffer exhaustion, upped limits as a temporary fix.

Switched to instaced drawing for source[/intermediate] runs too, reducing that data transfer footprint by 50%.

Update CRTConstants.hpp
Lack of data duplication means this storage can be smaller.

Switched back to normal frame drawing logic and cleaned up the circular range stuff a little, to make it clear that no errors lie there.

Proven through deliberate inefficiency: the issues are (i) texture upload; and (ii) buffer wraparound.

Made a decision to clean up by creating per-shader classes. Well, more or less. First thing to be factored out: the output shader.

Factored out wraparound buffer addressing where it's otherwise going to get really repetitive; need to look at using the same approach for the glTexSubImage2D step at least but that probably means properly encapsulating the buffer builder's state.

Corrections back towards composite output: fixed misnamed constant, ensured the CRT doesn't write nonsense to the output buffer, ensured it grows three vertices at a time rather than six when desired. Net effect should be that the output stage is working again, with the input processing remaining to fill in.

Made an attempt to consolidate timestamp bases to a single vector and hence to lump all geometry into one or two calls, with no repetitive setting of a uniform. I'm not sure the result is correct yet.

A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything.
