Uses performance.now instead of Date.now and it also runs at 60fps in Chrome now, thanks to the line:
this.lastTickTimestamp = t - (delta % this.interval);
changed from just
this.lastTickTimestamp = t;
It's kinda hard to understand why that helps but I found it and the explanation at http://codetheory.in/controlling-the-frame-rate-with-requestanimationframe/
