@raph Hi Raph, I watched your great talk about Xilem, very interesting stuff,
looking forward to see where it will go.

I am currently building a 2D sprite editor in Rust, so this problem you
posted is something I had to deal with recently (but without the parallelism).
If you calculate the size of the line, you can find the intermediate points
and give each pair to a thread/task, would that work?
