2002-01-03  Havoc Pennington  <hp@pobox.com>

	* src/window.c: use meta_XFree not XFree

	* src/display.h (meta_XFree): add null-safe XFree

	* src/util.c (meta_warning): have message prefix indicate that
	it's a warning
	(meta_fatal): indicate it's an error

	* src/window.c (update_sm_hints): clean up using
	meta_prop_get_latin1_string
	(update_role): ditto
	(read_client_leader): clean up using meta_prop_get_window
	(update_net_wm_type): clean up using meta_prop_get_cardinal
	(update_initial_workspace): ditto
	(update_net_wm_type): clean up using meta_prop_get_atom_list
	(read_rgb_icon): get result from XGetWindowProperty return value
	not from error trap
	(update_kwm_icon): ditto
	(meta_window_new): fix to read WM_STATE correctly
