Reintroduced the CRT delegate and the 2600's automatic region switching. Albeit that the CRT itself doesn't adjust properly to new timings yet.

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.

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.

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.
