Three Dollar Quill

Okay, I've got prototype code for generating "nice-enough" space-filling curves, modulo a minor cheat in what is technically a corner case. This covers part of what I need for Riemersma dithering; the rest is handling the actual quantization etc.

In terms of neat code stuff, the next things to do are to set up the overall pipeline logic and write a debug function that handles the fact that light is dark and dark is light.

In terms of project workflow stuff, I really need to get back to working with Jujutsu, and figuring out how to make some kind of reasonable commit out of the complete nonsense I've managed to accrue as a result of not wanting to think about how Jujutsu works.

We'll see if I have the discipline to do that, tomorrow. For now, bed.

Good night.
