Yeah, if you look at #2 I've been meaning to test across all browsers. I'm guessing if IE11 is broken, then IE 9 and 10 are as well.

I can take a look when I get a chance, but if you figure it out first feel free to submit a PR!

I was using the canvas.width = canvas.width hack to clear the canvas, which worked in all other browsers. The canvas is now cleared properly using context.clearRect(), and paths are created properly with context.beginPath().
