Patch v1

static const OcclusionNotificationHandler occlusionNotificationHandlers[] = {
 156    { WKOcclusionNotificationTypeApplicationBecameVisible, applicationBecameVisible, "Application Became Visible" },
 157    { WKOcclusionNotificationTypeApplicationBecameOccluded, applicationBecameOccluded, "Application Became Occluded" },
 158    { WKOcclusionNotificationTypeApplicationWindowModificationsStarted, applicationWindowModificationsStarted, "Application Window Modifications Started" },
 159    { WKOcclusionNotificationTypeApplicationWindowModificationsStopped, applicationWindowModificationsStopped, "Application Window Modifications Stopped" },
 160};

Minor observation: The registration of visible notification used to precede the occluded notification and the order was reversed for unregistration.  Just a defensive style.  Since the order is now fixed, the log line can be replaced with an ASSERT and eliminate the return statement entirely.

Revised patch

Revised patch for reference. Removes some unnecessary consts that Darin mentioned to me, and changes the WTFLogAlways to ASSERT_WITH_MESSAGE.

This was landed back in r147593.
