Obeys modals' zoom.
...
Subject to an attempt at factoring aspect ratio differences.

Introduces a stencil buffer plus the inter-frame clearing it allows.

Adds first_scan to LineMetadata.
...
Also reorders `Line` fields to match `Scan` fields, just for visual consistency.

Adds an intermediate buffer to correct inter-frame smoothing.
...
Also goes someway back to the old scan output scheduling, albeit presently with limited thread safety.

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.

Takes a shot at adding RGB -> S-Video and composite conversion, for all RGB types.

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!

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.

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.
