Documented this interface, albeit that the English could do with a second pass, and very sightly simplified inline with current usage.

Renamed the 'input buffer builder' to the 'input texture builder' to be explicit about what sort of buffer, and killed the prefix since it's namespaced. Also switched to std::vector.

Both pathways start with a buffer that clears to black. So no need to keep going on about it.

Eliminated zoned clearing, in favour of a complete buffer clear on each load and attempted to reduce locking. But imperfectly.

Normalised on std::vector rather than std::unique_ptr<uint8_t *> as (probably?) more idiomatic. Improved structure slightly. Introduced a container for line data, albeit one that isn't yet used.

It appears the Vic's output is sine-ish, after all. Also adjusted centre of display, simultaneously adding some validation on that.

Realised that phase time can fit inside a single byte, since it's always (well) within the first quarter of the line — and if it somehow weren't (?) then taking it modulo the frequency would do.

Switched to a more rational interface, ensured output_level will work when eventually needed, and that neither it nor output_data attempts a recursive lock.

Withdrew the pixel unpack buffer in order to avoid the potential for a paused machine to be undrawable. The cost is at least an extra memcpy per frame; I'm letting the driver worry about the whole process for now.

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

Switched to an in-framebuffer approach to phosphor decay, which might be acceptable now that every single pixel is being painted, re-emphasises luminance and stretched sampling period for the two FIR filters as well as decreasing the amount of signal that is retained, subjectively to improve output.

This, at least, is an attempt to decode chrominance, as yet unfiltered, and not commuted to RGB (and possibly packed incorrectly).

Factored out wraparound buffer addressing where it's otherwise going to get really repetitive; need to look at using the same approach for the glTexSubImage2D step at least but that probably means properly encapsulating the buffer builder's state.

Eliminated use of zero-alpha runs to clear new lines in the intermediate buffer in favour of a scissored glClear. It's just an easier way to scale the current approach to three intermediate buffers.

Fixed: issue was (i) always thinking the entire source run buffer needed to be issued; and (ii) having fixed that, always thinking that the block that needs redrawing doesn't overflow the buffer. Fixed both. 'Television' mode is now working without explicit synchronisation (and with a lot less work).

Smoothed output device changes, killing some dead state. Added an explicit glFinish to suggest that the problem is synchronisation rather than any sort of data or shader error.

Trivially fixed. Appears to confirm an off-by-one error in the television implementation. Which would explain one of the visual phenomena — a repeating corrupted line.

Nothing of substance different; main current mystery: why do old frames recur and why does other jumpiness occur? Do I need some explicit synchronistion?
