Even better: why include the 'Input' prefix when there's only one?

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.

At the expense of API simplicity, at least for now, resolved the most glaring cause of dirty lines.

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.

Actually, I guess that to fulfil the contract I can't silently decide not to draw if I'm being told I definitely need to draw.

glClientWaitSync appears to be a busy wait, at least on my machine. But why wait indefinitely anyway?

Demonstrated that issue is coloured borders, made a guess as to buffer exhaustion, upped limits as a temporary fix.

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

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.

Made an attempt to queue uniform changes until the next call to bind. That's to allow usage from other threads.

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

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.
