Gives the CRT the ability to move iCoordinate multiplication outside of the fragment loop.
That resolves precision issues, as were plaguing the Apple II.

Formalised the reasoning behind the colour phase fix-up and made it an opt-in per-caller value. Only the Oric currently needs to opt in.

Performed a very naive shuffling of output builder sets onto the OpenGL queue. Which makes the frequency switcher work properly from it's possibly-contextless thread.
