I think my implementation of this algorithm is broken. It does something, but the output looks bad.

2021-04-25Remove cairo dependencywip-nocairojaseg13-342/+157
We initially used Cairo for its bezier flattening algorithm. That algorithm turned out to be a bit too imprecise at the scales we're working at here (#17), so I ended up porting over some code from Antigrain Graphics. The only other thing we used Cairo for was debug output and coordinate transforms, so I just wrote the relevant vector math in a small header file, deleted all debug output code and thus eliminated the cairo dependency. This is a step towards Windows builds.
2021-04-24Replace cairo curve flattener from Anitgrain Graphicsjaseg5-35/+268
This also fixes an issue where non-closed curves were not dilated properly.
