Better Image Tracer for Grease Pencil

I'm particularly excited that Potracer has been merged into master and it does the job well for generalized images. But I feel it's lacking in some aspects for its original intention which is to vectorize animation sketches quickly. There was a paper in SIGGRAPH 2019 titled "Vectorization of Line Drawings via Polyvector Fields" which tackled the job fantastically.

The reference code has been recently been uploaded to github.com/bmpix/PolyVectorization and while it's been a pain in the default cube to compile, the results it generates are very promising. This would be as much of a game changer as Potracer will be for the grease pencil animation community, and it would be great if someone would like to tackle it!
