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