Let's see!

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.

|
Attempts to establish interface to decouple scan output from generation.
Restores some functionality that had dropped out in the interim: diagonal scans, decoupling of scan scaling from timing of the composite subcarrier.

Eliminates the concept of an iCoordinate.
Real-life precision appears not to support the idea of sub-sample pixel storage.

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.
