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?

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

With some effort towards scans, but incompletely so.

This is possibly at least dispatching an empty command buffer correctly.
