This is really beautiful. A few questions:
- how do I add and delete points on a path?
- how do I change the node type? Eg, if there are no handles, how do I get handles (antlers I think you call them in the code).
- How do I go from colinear handles to "broken" handles: handles that form an angle at the node, so I can have two different curves joined at an acute angle at one node?
- How do I do intersections, unions, groups, layers, etc?
But I gotta say it again, it's really beautiful...
