        Screw around with Anders's ping patch so he'll get plenty of CVS
	conflicts. ;-)

	* src/display.c (meta_display_ping_window): spew warnings
	if we try to call this with CurrentTime
	(meta_display_ping_timeout): remove ping from the pending pings
	after it times out.

	* src/util.h: added PING debug category

	* src/display.c (remove_pending_pings_for_window): don't remove
	"tmp" just before "tmp->next", don't break out of loop after
	finding the first match
	(meta_display_open): no trailing comma in array init
	(event_callback): move the processing of ping replies into a
	separate function

	* src/screen.c (set_supported_hint): add _NET_WM_PING to supported
	list

	* src/display.h: change gpointer to void*
