Enables blending; attempts to enable frame preservation.
...
The latter seems to be evidencing a double buffer at play. More investigation required.
On the plus side, the direct route is still well within GPU budget at 4k on my Core M. So a huge improvement there.

Ensures all input data types are parseable in Metal.

Though now I need to think a bit more about the best way to compose signal-type conversions, and whether output-type calculations (i.e. gamma, brightness) are applied.

Seemingly proves that proper geometry is reaching Metal by drawing scans.

No in-buffer accumulation yet, but this is progress. If I can add accumulation and stencil clearing, I'm not doing badly.

Makes an attempt to have the emulator fill the actual GPU buffers.
...
Not that they're drawn from correctly yet. I might first take a run at a new quick-path output route for emulated RGB displays, that just seeks to use the scans directly. No intermediate buffers. Besides probably being a good feature, it'll be a good way to ramp further up with Metal.

Having learnt a bit more: eliminates Metal attribute tags, switches to more natural expression of structs.

Also thereby eliminates the need for a forced alignas(4) on various structs.

Adds adjustment for display aspect ratio.

While also realising that I appear to be getting away without an MTLVertexDescriptor for Scans. Maybe OpenGL has prejudiced me, and they're actually optional for interleaved data?
