Rob Adams 993c7075f3 Precompute groups to guarantee that meta_group_list_windows always returns
2003-06-04  Rob Adams  <robadams@ucla.edu>

	Precompute groups to guarantee that meta_group_list_windows always
	returns the correct list of windows.  See Bug #96973

	* src/window.h: change cached_group variable to group

	* src/window.c (meta_window_new): change cached_group to group and
	call meta_window_compute_group

	* src/groups.c (meta_window_get_group): simply return
	window->group rather than computing it and returning
	window->cached_group
	(meta_window_compute_group): new function computes window->group.
	Designed to be called once from meta_window_new
	(remove_window_from_group): change cached_group to group
	(meta_window_group_leader_changed): call meta_window_compute_group
	instead of meta_window_get_group
