Simplifies and corrects low-resolution colour generation.
Possibly disproving the premise for this whole experiment, all colours seem immediately to work correctly. Hmmm.

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

Put enough in place to get a visual representation of video memory.
Not the correct one, and so as to indicate that the machine isn't booting, surprisingly.
