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.

Started sketching out the delegate interface that will allow a branch from the CRT into whatever native display system is used by a particular platform.

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.

Introduced enough logic that the Atari 2600 is being run, at least. No output yet though because (i) it has no-one to send output to; and (ii) there's nobody that knows how to display output. Hmmm.

Performed the bare necessary steps to get my little OpenGL view to create a CVDisplayLink and then repaint itself in time with the display.

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.

Shuffled things and guessed at things until the Xcode project was happy being subservient to the project proper.

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.
