  Regions too big to be interactions should still be checked for occlusions

Reviewed by Tim Horton.

Before we discard an interaction region based on its area, check to
see if we should generate a corresponding occlusion region.
(Occlusions use a higher area limit.)

* Source/WebCore/page/InteractionRegion.cpp:
(WebCore::interactionRegionForRenderedRegion):
Extract the interaction area check to a variable.
Use it as part of the occlusion branch's condition.

* LayoutTests/interaction-region/full-page-overlay-expected.txt:
* LayoutTests/interaction-region/full-page-overlay.html:
Update the overlay test to cover this case.
