Better smoothing of crayon points.

[Fishrock123]

This will take a while, but should be something to work towards.

mondrian is going to need a smoothing algorithm for crayon points.

I would use Schneider's path fitting algorithm:

• demo http://paperjs.org/examples/path-simplification/
• original implementation: http://tog.acm.org/resources/GraphicsGems/gems/FitCurves.c
• JavaScript port: https://github.com/paperjs/paper.js/blob/master/src/path/PathFitter.js

👍 to @jarek-foksa's suggestion.

I'll take an hour one day to learn about Schneider's algorithm. Haven't heard of it before. That paperjs demo is amazing.

The crayon tool uses a simple algorithm I came up with. It only produces smooth lines when one draws quickly. I'd love to port a better algo to it.

I like the smoothed results of Schneider's, but it does not do corners well. —

@wraybowling Oh wow, you're right. (Try drawing boxes in the demo.)

I would be more inclined to go with something a tad slower and more precise, generally.
