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.

The penny has finally dropped that I can drive the CPU stuff in a manner completely decoupled from the GPU stuff. For much improved parallelisation.

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.
