The semantics might need better exposition but: fixed UniformXfv calls plus matrix calls, documented new semantics on all setters.

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.

Actually, that should probably be 1/outputTextureSize, as the output range is -1 to +1.

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.
