I haven't played around with scrollbars in Squeak / Cuis yet, but in
many (most?) GUIs its up to your code to maintain the illusion of
position in the virtual space inside the scrolling area. (i.e. scrollbar
position, size, and actually drawing the visible portion of the view is
up to you to manage)
