mutter/src/window.c
Havoc Pennington fabc5507f3 be robust against the panel's lame "set a negative number for struts" 
2003-01-22  Havoc Pennington  <hp@pobox.com>

	* src/window.c (update_struts): be robust against the panel's
	lame "set a negative number for struts" thing, even though
	we'll also fix the panel.
