<DD>QTCanvas calls this method when the client should redraw itself.

 drawing area needs to be redrawn - then this area shall be passed in
 using the invalidRgn. Otherwise this will be null in which case the
 client should redraw itself entirely.<DD><DL>

<DL>
<DD>Returns an object that invalidates a sprite. When a DynamicImage
 is a member of a SWompositor and the DynamicImage presents a
 changing image (for example a movie), the TwoDSprite that presents
 that image in the SWCompositor must be invalidated so that it will
 redraw the Sprites image in the next composit cycle. The Invalidator
 object is used to perform this function by the SWCompositor if the object
 itself cannot perform the invalidation.
 Can return null if the DynamicImage does not require the SWCompositor
 to invalidate it (or the object is in a state where its image won't change).
 <P>
 The Invalidators provided with objects that implement the DynamicImage
 interface will execute at the scale and period of the Compositor
 when they are created.<DD><DL>
