nuke the lists of struts here, to improve confidence that we never try to

2003-06-26  Havoc Pennington  <hp@pobox.com>

	* src/workspace.c (meta_workspace_invalidate_work_area): nuke the
	lists of struts here, to improve confidence that we never try to
	use them after a window with rects in the list gets freed.
	(it wasn't broken before I don't think, just making the
	code more robust against future mods)

	* src/window.c (meta_window_update_struts): replace magic "75"
	with a macro

	* src/constraints.c (constraint_hints_applies_func): don't apply
	hints to maximized or fullscreen, rather than only fullscreen
	(constrain_move): add paranoia max number of iterations to the
	heuristic loop
