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.

Definitively eliminated the additional y filtering step; if I'm going to work to ensure always four samples per colour cycle, I can put the channel separation coefficients directly into their shaders, cutting down on samples.

Moved underscores, removed indirections where they're not necessary, converted those names that were still looking very Objective-C and moved the GL fence variable into the private area, where it should always have been.

Renamed the 'input buffer builder' to the 'input texture builder' to be explicit about what sort of buffer, and killed the prefix since it's namespaced. Also switched to std::vector.

Normalised on std::vector rather than std::unique_ptr<uint8_t *> as (probably?) more idiomatic. Improved structure slightly. Introduced a container for line data, albeit one that isn't yet used.

Withdrew the pixel unpack buffer in order to avoid the potential for a paused machine to be undrawable. The cost is at least an extra memcpy per frame; I'm letting the driver worry about the whole process for now.
