Reviewed by Žan Doberšek.

The problem is that ScrollingTreeNicosia::scrollingNodeForPoint() is
returning an overflow node containing the given point, but its event
region doesn't contain the point.

* Source/WebCore/page/scrolling/nicosia/ScrollingTreeNicosia.cpp:
(WebCore::collectDescendantLayersAtPoint): Check also the event region contains the given point.
* Source/WebCore/platform/graphics/nicosia/NicosiaPlatformLayer.h: Add EventRegion.
* Source/WebCore/platform/graphics/texmap/coordinated/CoordinatedGraphicsLayer.cpp:
(WebCore::CoordinatedGraphicsLayer::setEventRegion):
(WebCore::CoordinatedGraphicsLayer::flushCompositingStateForThisLayerOnly):
* Source/WebCore/platform/graphics/texmap/coordinated/CoordinatedGraphicsLayer.h:
