nit - add a NOTREACHED() here.

[jdduke (slow), 2013/11/21 16:55:29]

Hmm, I have the assert above for type being a valid touch event, and we don't
want to do anything for TouchStart, but I guess I can be more explicit there.

[tdresser, 2013/11/21 17:02:48]

Ah, good point. I do like this somewhat better though.
