Tidied up a little, mostly bumping things out of just-in-time creation that I can just do well in advance.

In search of the cause of performance issues again, excised the per-pixel sin until it can be further evaluated.

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.

Switched horizontal sync detection back to differential, switched the Electron to an XOR-style sync output (believed to be accurate, but I need to check), fixed some latent issues around vertical sync detection.

Realising I've managed to confuse input and output, started shift to 'source' for what 'input' was.

Expanded interface to rgb_sample to eliminate its need to make assumptions about globals, used expanded interface to compact Electron data to two pixels per byte.

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.

Keeping a buffer permanently bound is apparently illegal. So back to copying in on demand. Which I think still improves on synchronisation, but not much.

As messy as it is, this use glMapBufferRange to avoid explicit buffer submits.
