Finally embedded the actual calculator (which was surprisingly easy, thanks desmos team!) Also, I fixed a bug where control points were being rounded to a grid at small font sizes.

I don’t think the current error metric for bezier curve flatness is good, since it’s a distance that depends on the size of the curve (which depends on font size). Maybe I could just scale the threshold by the font size, but I’d have to look more into it.

That’s why in the new screenshot, there are way too many samples, even though I set the tolerance slider to the max. The sampling now happens in glyph space, which is at a way larger scale (1em = around 1000 units) compared to the output space, and I forgot to change the slider’s bounds.

Also did a bunch of rewrites, and bumped the text shaping/font loading dependencies; their new API is so much simpler that I was able to get rid of a dependency I previously needed. It’s funny, but I regret that I had to deal with the old API.
