Description Brent Fulgham 2015-03-14 21:07:14 PDT

Zooming a page with scroll snap points causes the snap point logic to do the wrong thing. We should be properly dealing with zoomed state when searching for the nearest snap point, and when animating to the target location.

When computing snap point targets, we need to account for the current page zoom. This is currently ignored.
