Trackpad is generating wheel NSEvents which have both deltaX and deltaY set to
0. These events are ignored by WebCore and so get forwarded to the view. There
they actually make the NSScrollView scroll. I wonder what is the logic there...
Mouse wheel does not generate these (0,0) events so does not have the same
scrolling problems.

Trivial solution of just blocking (0,0) events seems to degrade speed and
general feel of trackpad scrolling.
