/**
* meta_window_get_transient_for:
* @window: a #MetaWindow
*
* Returns the #MetaWindow for the window that is pointed to by the
* WM_TRANSIENT_FOR hint on this window (see XGetTransientForHint()
* or XSetTransientForHint()). Metacity keeps transient windows above their
* parents. A typical usage of this hint is for a dialog that wants to stay
* above its associated window.
*
* Return value: (transfer none): the window this window is transient for, or
* %NULL if the WM_TRANSIENT_FOR hint is unset or does not point to a toplevel
* window that Metacity knows about.
