nsCocoaWindow currently responds to all NSWindowDelegate calls to windowDidChangeOcclusionState by potentially sending a OcclusionStateChanged event. During a native fullscreen transition, a window may move through occlusion states before settling on its final state, which is the only one that is actually relevant to the user. However, these changes in occlusion state create timing windows of failure for various API calls that require a window to be visible. To avoid this unwanted side effect, this change makes nsCocoaWindow ignore calls to that method during the fullscreen transition. The final call -- after the transition -- will send the steady-state OcclusionStateChanged event.

In addition to suppressing the sending of OcclusionStateChanged events,
this also creates a helper method that is called by both
windowDidEnterFullScreen and windowDidExitFullScreen, which makes their
implementation better match other fullscreen delegate methods.
