[iOS][WK2] Adjust the tile coverage on the scrollview's edges
https://bugs.webkit.org/show_bug.cgi?id=130884
Patch by Benjamin Poulain <[email protected]> on 2014-03-27
Reviewed by Dan Bernstein.
* platform/ios/ScrollViewIOS.mm:
(WebCore::ScrollView::computeCoverageRect):
Pull back the future rect inside the contentRect if it goes outside.
There is no point in retiling for rubberbanding and the extra tiles should be always be
on the opposite side to the edges.
