 // Unity and some configurations of GNOME have a Apple-like menu bar at the top
 // of the screen that changes depending on the active window. These mainly work
 // by inspecting the application's widget hierarchy, and intercepting any
 // GtkMenuBar found. Thankfully, these systems don't check to see if the menu
 // bar itself is visible, so we insert a GtkMenuBar into the window hierarchy
 // and set it to be invisible.
