Informs GTK+ on which monitor a menu should be popped up.
See gdk_monitor_get_geometry().
This function should be called from a #GtkMenuPositionFunc
if the menu should not appear on the same monitor as the pointer.
This information can’t be reliably inferred from the coordinates
returned by a #GtkMenuPositionFunc, since, for very long menus,
these coordinates may extend beyond the monitor boundaries or even
the screen boundaries.
