Scroll bars that have AUTOKNOBs must have their GadgetRender field point
to an Image structure.  Intuition initializes and maintains this structure 
itself, as I recal, so you won't have to do anything but allocate space
for it and link it into your gadget.  Each scroll bar needs to have its
own.  I believe that intuition uses this structure to make the rectangular
knob (its width and height seem to indicate this).

Hope this helps.
