da4d883321 Adds first, incomplete attempts to talk to a ScanTarget from the CRT.
Does away with the hassle of `unsigned` while I'm here; that was a schoolboy error.

c97c5fa03a [Re-]recalibrates CRT retrace period and affected view windows.
In the hope of moving the CPC closer to the real CTM visible area.

0c65385c82 Undoes older interpretation of alternating phase.
I now understand, hopefully, that it's only the phase of the second colour component that alternates. That has the pointwise effect of reversing the colour signal. Hence the effect of phase errors cancelling themselves out up on successive lines up to a point.
