Use 3D bezier curves instead of point lists and vertices

[timcreatedit]

Using 3D bezier curves instead of lines would allow for:

• Simplification of lines (less space complexity)
• Smoothing lines and pressure
• "Perfect" collision detection for eraser
• ... potentially more

This is probably not gonna happen for a while (maybe for 1.0), since the current approach works well enough for our use-case, but we're always happy about PRs

or maybe integrate https://github.com/steveruizok/perfect-freehand-dart ?
that would allow to keep current points list approach and still give this more manual feel from curves. Just an idea but that would make Scribble fantastic ;)

It's been integrated since 0.9.0 :)
