curves with very flat angles do produce to many intersection

[schriftgestalt]

I tried in the demo with this in1:

var in1 = [[
	{"x": 818, "y": 928,"on": true},
	{"x": 490.58167701305132, "y": 928,"on": false},
	{"x": 119.36605542567935, "y": 789.56922252138634,"on": false},
	{"x": -43.128428624165792, "y": 598.83193769835407,"on": true},
],
[
	{"x": -264.0, "y": -98.0 ,"on": true},
	{"x": -264.0, "y": 211.28227904194409, "on": false},
	{"x": -142.41574982367075, "y": 518.24809985172965, "on": false},
	{"x": 56.865397392878748, "y": 700.49092773837606, "on": true},
],
];

Actually it wont.

Have you tried to browserify the demo/index.js to demo/index.packed.js?

The intersection part looks like this:

I don't know almost anything about JavaScript so I don't know what 'browserify' means.

@schriftgestalt The latest commit may fixed this... in the demo.
The code is actually correct, I only updated the demo scene.
Browserify is a script packer that converts Node-ish scripts into something can be run on web pages.
