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.

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

Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE.

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.

Introduced the ability simply to piggy-back off the CRT's natural phase for the colour burst, thereby eliminating a couple of redundant independent attempts in the Oric and Electron.

Reintroduced the CRT delegate and the 2600's automatic region switching. Albeit that the CRT itself doesn't adjust properly to new timings yet.
