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.

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.

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

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.

Made a decision to clean up by creating per-shader classes. Well, more or less. First thing to be factored out: the output shader.

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.
