Spotted error was in texture target all along. This now gets as far as showing something a lot like the correct display, but precision is way off. Way off.

Added first attempt at performing the first step of television output: mapping from source data to the first of the processing buffers. It's immediately obvious that my eye coordinates are off.

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.

Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow.

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.
