Corrects use of composition buffer.
...
Something is still very obviously amiss in colour processing somewhere down the line, but the correct forms are once again visibly in evidence.

Removes ONE_BIG_LOCK, having effectively neutered it anyway.

To an extent. Doesn't currently deal with cropping of machines when the window aspect ratio is smaller.

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.

These are just more details on the meaning of the colour spaces, so I think they belong here.

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.

df89a8771c
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.

38960a08d6
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?

Guarantees alignof(4) on all GPU-bound structures.

Taken as given: Metal's requirement here is reasonable enough that it'll either be the same as other frameworks, or at least possibly help them down a fast path.
