Fixed: was off by one on pixels, allowing four extra pixel output cycles per line.

Added something of the ball counter, but without yet a working HMOVE it's prone to error.

Generalised slightly, to allow events to be queued up to eight cycles in advance; most importantly each event gets to pick its own delay.

Introduced a four-cycle delay between playfield fetch and display, curing Yar's Revenge. Also disabled barrel roll scanling colouring again. I really need to make my mind up on that.

These functions appear correctly to model the NTSC and PAL palettes; the CRT's attempt to switch function doesn't work properly yet though.

Oh, of course, it's that the output vertex array doesn't get initialised unless there's an RGB shader program. Silly oversight. Fixed. And switched back to TV output for correct colours.

Added a dump-the-input default RGB output shader. Which at least proves that the Atari 2600 is generally still working.

Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.

Got a bit higher level in CRT timing specification. Which internally allows it now to infer the colour clock frequency. Which will be helpful momentarily.
