STR:

1) Load test case in https://bugzilla.mozilla.org/attachment.cgi?id=8634948
2) Zoom in a couple of times, scroll to the bottom of the page.
3) Zoom out a couple of times, the bottom of the page isn't repainted.

See attached screenshot. This only happens with APZ. Disabling APZ fixes the issue. Tested on OS X, 10.10.
Seems like we just don't clamp the scroll position after the full zoom causes a change in the page size.
Patch on bug 1187792 seems to fix this also.
Depends on: 1187792
Marking fixed by bug 1187792; please reopen if you still see this happening.
