chasing the thumb in a scrollbar

The thumbPosition will give you the position of the thumb relative to  
the endvalue of the scrollbar itself.  So that if the scrollbar's  
endvalue is set to 100 (default) and it's halfway along, the thumbpos  
will be 50.  If the endvalue is set to 200, it will show 100.  But I'm  
trying to place a graphic based on the actual thumb position relative  
to the screen, not the scrollbar.
