Fixed mistimed reset of the target output line. Now all that's left is occasional noise.

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.

.reset is the more normal way to reassign a unique_ptr.

Permitted a wider error window on vertical sync, tidied things up a little and started trying to move towards full implementation of the OpenGL contract.

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.

Quickest first attempt to switch to instancing for the output array. Texture coordinates seem to be off.

Fence sync tied up. Remaining glitches are likely off-by-one-type errors but we'll see.

Switched back to normal frame drawing logic and cleaned up the circular range stuff a little, to make it clear that no errors lie there.

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.

With a lot of logging also currently ongoing, fixed circular ranges for clearing and when covering an entire buffer.

Proven through deliberate inefficiency: the issues are (i) texture upload; and (ii) buffer wraparound.
