Adds superficially correct compositeSampleLuminance8Phase8 function.
...
Thereby uncovering a minor error in my decoding of colour phase.

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.

Does just enough to get 8-bit RGB and 1-bit luminance machines to display.
...
Assuming an 'RGB' output.

Ties everything together in an attempt to display RGB scans.
...
I'm actually just getting a mess of pixels, but it's something!

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.

Eliminates the quad buffer.

Vertices can be adduced from vertex ID.

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?

Does just enough to get the correct (aspect ratio aside) output of scan outlines.
...
So, up next, can I start streaming these things?

Gets some uniforms in on the action.

With some effort towards scans, but incompletely so.

This more closely relates to what I actually want to do.

... by switching out NSOpenGLView for MKLView with no drawing infrastructure yet in place.
