Three Dollar Quill

• Wednesday: I ran into some trouble with the thermal printer. I don't recall that I fixed it to my satisfaction.
• Thursday: I did manage to get it to work for other cases, at least.
• Friday: I did further experimentation with the printer.
• Saturday: I experimented with the dithering options in Pillow, which are pretty limited, so I'm planning to roll my own.
• Sunday: I made some progress towards rolling my own versions of various kinds of dithering, but also the project repository is a mess.
• Monday: I cleaned things up, and potentially got some forms of dithering working, though I haven't actually checked.

Next week, I'll try to make more progress, and maybe write up the space-filling curves stuff, since I did have to put some effort into understanding what's going on, and also it's possible that I can get rid of that corner case without too much effort.
