	* src/screen.c (set_supported_hint): add _NET_WM_STATE_HIDDEN
	to _NET_SUPPORTED

	* src/keybindings.c (meta_set_keybindings_disabled): put in header
	file, to fix warning.

	* src/display.c (meta_display_open): add _NET_WM_STATE_HIDDEN atom

	* src/window.c (set_net_wm_state): set _NET_WM_STATE_HIDDEN for
	shaded and minimized windows
	(meta_window_show): call set_net_wm_state() if we map the window
	or frame
	(meta_window_hide): call set_net_wm_state() if we unmap the window
