2004-06-17  Elijah Newren  <newren@math.utah.edu>

	Add support for _NET_WM_USER_TIME

	* src/display.c:
	(meta_display_open): Add _NET_WM_USER_TIME to atom_names[],
	(event_callback): Manually set _NET_WM_USER_TIME upon KeyPress
	(doesn't work since keyboard isn't grabbed) and ButtonPress (does
	work), this is just a fallback for applications that don't update
	this themselves.

	* src/display.h: (struct _MetaDisplay): Add atom_net_wm_user_time field

	* src/screen.c: (meta_screen_apply_startup_properties): Check for
	TIMESTAMP provided from startup sequence as well.

	* src/stack.c:
	s/meta_window_set_stack_position/meta_window_set_stack_position_no_sync/,
	(meta_window_set_stack_position): New function which calls the
	meta_window_set_stack_position_no_sync function followed immediately
	by calling meta_stack_sync_to_server.

	* src/window-props.c:
	(init_net_wm_user_time), (reload_net_wm_user_time): new functions,
	(reload_wm_hints): also load atom_net_wm_user_time

	* src/window.c:
	new XSERVER_TIME_IS_LATER macro (accounts for timestamp wraparound),
	(meta_window_new_with_attrs): add timestamp attributes,
	(window_takes_focus_on_map): use TIMESTAMP from startup
	notification and _NET_WM_USER_TIME to decide whether to focus new
	windows,
	(meta_window_show): if app doesn't take focus on map, place it
	just below the focused window in the stack
	(process_property_notify): check for changes to _NET_WM_USRE_TIME,
	(meta_window_stack_just_below): new function

	* src/window.h:
	(_MetaWindow struct): new fields for initial_timestamp,
	initial_timestamp_set, net_wm_user_time_set, and net_wm_user_time,
	(meta_window_stack_just_below): new function

src/stack.h
