<DD>The Invalidators typically ignore time and rate values and invalidate
 their sprite. The default implementation will always invalidate the 
 sprite - subclasses can refine the actual conditions under which
 invalidation is appropriate.
 However an Invalidator subclass could of course use the time and rate values.<DD><DL>
