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.

Switched key that maps to FUNC from command to option. Logic is that command may frequently be used for performing an action which changes the key window, in which case we won't realise if it is released.

Set the 'options' windows to hide on application deactivation so that they don't cluelessly sit on top of the rest of the system.

Wired in options, at least getting as far as the Objective-C bridge. Then fast loading makes it to the emulated machine, display output type doesn't.

Shuffled further in an attempt to get as far as having static but incorrectly-interpreted pixel data on screen. It's not currently static. So work to do.

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.

I discovered a further post on this on the STH forums; apparently the Electron simply asserts sync continuously. No breaks.

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.
