	* src/screen.c (set_supported_hint): we didn't claim to support
	_NET_ACTIVE_WINDOW so gtk_window_present() didn't work. Mumble.
	Only worked with tasklist because libwnck didn't check for
	WM support.

	* src/window.c (meta_window_free): clean off window state
	when windows are withdrawn, to avoid sticking dialogs
	to their initial desktop.
	(meta_window_queue_calc_showing): return if window is withdrawn
