-// ExternalFocusTracker tracks the last focused view which belongs to the
-// provided focus manager and is not either the provided parent view or one of
-// its descendants. This is generally used if the parent view want to return
-// focus to some other view once it is dismissed. The parent view and the focus
-// manager must exist for the duration of the tracking. If the focus manager
-// must be deleted before this object is deleted, make sure to call
-// SetFocusManager(NULL) first.
-//
-// Typical use: When a view is added to the view hierarchy, it instantiates an
-// ExternalFocusTracker and passes in itself and its focus manager. Then,
-// when that view wants to return focus to the last focused view which is not
-// itself and not a descandant of itself, (usually when it is being closed)
-// it calls FocusLastFocusedExternalView.
