* meta_compositor_window_mapped() and meta_compositor_window_unmapped() are
* notifications when the toplevel window (frame or client window) is mapped or
* unmapped. That is, when the result of meta_window_toplevel_is_mapped()
* changes. The main use of this is to drop resources when a window is unmapped.
* A window will always be mapped before meta_compositor_show_window()
* is called and will not be unmapped until after meta_compositor_hide_window()
* is called. If the live_hidden_windows preference is set, windows will never
* be unmapped.
