Fix one: vertical scan speed was failing to allow for the number of cycles in a line.

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

Commented the heck out of this thing, to put my thoughts in order if nothing else.

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.

This looks a lot closer to correct. The loss of horizontal sync during vertical sync is odd but the two should be fully decoupled in here. I'll have to check. Probably I've got something wrong. There are approximate sinusoidals when re-establishing sync, so that's promising as to the flywheel.

Made complete attempt at sync discrimination. But I seem somehow to be locking such that horizontal sync is in the middle of the line. Obviously my flywheel is at fault somehow.

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.

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.
