Log Message
<rdar://problem/14051357> Web processes sometimes remain in a suppressed
state after their window is unoccluded.
The code in WKView that responds to occlusion notifications was incorrectly
treating the window's occlusion state as being an enum rather than the set of
flags that it is.
Reviewed by Oliver Hunt.
* UIProcess/API/mac/WKView.mm:
(-[WKView _windowDidChangeOcclusionState:]): Test only the visibility state.
(-[WKView setWindowOcclusionDetectionEnabled:]): Ditto.
