Realised why new shaders weren't taking. Very negligibly decreased Atari drawing cost.

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

Confirmed: it is inaccurate for a 6502 to self reset at power up. So that responsibility now rests in the machines.

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.
