Havoc Pennington 27e35b8bcd window is in fullscreen layer if any member of its group is fullscreen
2002-08-12  Havoc Pennington  <hp@redhat.com>

	* src/stack.c (compute_layer): window is in fullscreen layer if
	any member of its group is fullscreen

	* src/window.c (meta_window_unmake_fullscreen): update layer for
	whole window group
	(meta_window_make_fullscreen): ditto

	* src/util.c (meta_unsigned_long_hash): move hash/equal funcs for
	Window in here.

	* src/group.c: track window groups so we can do stuff with them.
