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.

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.

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.
