Title: Prevent jumpiness in scrolling animation if user scrolls manually at the same time.

Scrolling rapidly whilst animating can cause animation loop to try to
move in opposite direction to scroll, causing an ugly jumping effect -
particularly noticable with momentum scrolling on OSX.

Now animations correct themselves when the user scrolls during an
animation.
