108 the "restack()" functionality in GDK will only operate on windows in the same
109 "level" (e.g. two normal top level windows, or two utility windows) and will not
110 work across them. The splashscreen is on its own "StatusWindowLevel" so restacking
111 is not going to work.
113 So for OS X, we just hide ourselves.
115 Oct 2014: The Windows situation is similar, although it should be possible
