Smoothed output device changes, killing some dead state. Added an explicit glFinish to suggest that the problem is synchronisation rather than any sort of data or shader error.

Added: key states are all cleared if the window loses focus. Which resolves sticky key issues. Allowing me just to use command+option+O for options and map both command and option as FUNC.

Resolved potential crash if tape requests are made without one inserted. Softened glFinish to glFlush, though I'm still not sure I should strictly need even that.

Attempted to deal with the precision issues causing 'television' output currently to differ from 'monitor' output. Documented TextureTarget while I'm here.

Trivially fixed. Appears to confirm an off-by-one error in the television implementation. Which would explain one of the visual phenomena — a repeating corrupted line.

Nothing of substance different; main current mystery: why do old frames recur and why does other jumpiness occur? Do I need some explicit synchronistion?

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.

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.
