I am ready to announce the first release of the [`brush-strokes`](https://hackage.haskell.org/package/brush-strokes)library, which contains operations with quadratic/cubic Béziers that I needed to compute brush strokes.

Please refer to [the readme](https://gitlab.com/sheaf/metabrush/-/blob/master/brush-strokes/readme.md) for details!

I am sure there are still many rough edges, but I think it’s ready for general use.  
The next step is to improve the performance of the cusp-finding code, with work-in-progress for using Taylor models instead of interval arithmetic.

I’ve been using this library (in tandem with the companion [`brush-stroking`](https://hackage.haskell.org/package/brush-stroking) library, using Cairo as a rendering backend) to generate (vector!) shakuhachi scores like the following:

Congrats! This is incredibly cool, and I’m thrilled to see a first published version after all the work I’ve seen you put into it 🙂.

Now I just need to start looking for a nail to use this on…
