Made an attempt to switch to a triple-buffering scheme for CRT outputs, with an eye towards asynchronicity.

Attempted to switch to slightly more meaningful names within the CRT and implemented a delegate to investigate output. Working on it.

Made a quick attempt to accumulate a list of detected output runs. Which means finally having to specify normal frame height. I'm already at too many magic formulae though, so this will need proper revision when I'm next awake. Definitely my horizontal position advancement is way off.

Made some minor attempt at proper sync response. I think I've gone way off piste and overcomplicated it.

Rephrased the CRT as owning an arbitrary number of buffers and vending storage space for pixel output. That much better maps to potential implementations of this thing in GLSL, with ES 2.0's limitations kept in mind.

Fix 1: _horizontalTimer should be treated as read only out here.

Made first genuine attempt at outputting a meaningful CRT stream. Which shows some significant errors. So work to do.

Incoming: a 'CRT' class, to receive information intended for a cathode ray tube. To decode sync, etc.

This now goes just far enough to create an instance of Atari2600::Machine and push a ROM to it. Next jobs are to get a basic CRT emulation wired up, outputting to the window.

Imported what little I have so far in the way of a memory-access cycle complete 6502 and just enough of a pretend Atari 2600 on top to be able to see some playfields in ASCII art.
