Patch by Arvid Nilsson <anilsson@rim.com> on 2012-05-29
Reviewed by Rob Buis.

Fix build when accelerated compositing disabled, or debug build.

Also fix a bug where the selection overlay would not disappear properly
because of a typo in WebPage::removeOverlay(). Also convert said method
to early return style.

Debug build fixes contributed by Ming Xie.
