scroll_bar->compute
scroll_bar ->compute:
If graphical<-request_compute is not @nil, this method will:

  1. test if the scroll_bar<-object has the send method scroll_bar->bubble_scroll_bar. If this is the case, this method is called with this scrollbar as argument. The receiving object is supposed to activate scroll_bar->bubble, passing the current viewport settings to the scrollbar.
  2. If the scroll_bar<-object has all the methods scroll_bar<-start, scroll_bar<-view and scroll_bar<-length, the scrollbar will invoke them and update the viewport using the result. Backward compatibility only.

    If the scrolled object or the viewport is modified, the window or scroll_bar<-object should invoke graphical->request_compute on the scroll_bar to activate this mechanism.
