------- Additional Comments from Sami Kyostila <skyostil at google.com>
- Check that the currently scrolling layer still exists after a commit.
- Always clear the currently scrolling layer in scrollBegin().
- Apply the page scale to the layer visible rect instead of the content point.
- Don't collect scroll deltas if pinch zooming or a page scale animation is in
progress.
