[feature request] boolean path operations (unite, intersect, etc.)

[devdoomari]

paper.js already has boolean path operations built in. (http://paperjs.org/reference/path/#intersect-path)

I'd love to have that feature available for react-paper-bindings :)

I will try to port some of the examples in the following weeks, and will probably start with this. But I am looking for a job ATM, and I can't promise anything. You can try to make a PR 😉
