  44.      The VkScroll component provides something very similar to a Motif
  45.      XmScrolledWindow with XmNscrollingPolicy set to XmAUTOMATIC.  The
  46.      difference is that the VkScroll object is a component rather than a
  47.      widget, and that it supports the annotated scrollbar widget.

  59.           scrollbar.  Note that you need to call the setAnnotations() method
