 // Unity has an Apple-like menu bar at the top of the screen that changes
 // depending on the active window. In the GTK port, we had a hidden GtkMenuBar
 // object in each GtkWindow which existed only to be scrapped by the
 // libdbusmenu-gtk code. Since we don't have GtkWindows anymore, we need to
 // interface directly with the lower level libdbusmenu-glib, which we
 // opportunistically dlopen() since not everyone is running Ubuntu.
