  Summary:
    Implementation of a circle widget.
 
  Description:
    A circle widget draws a circle of the specified origin and radius inside
    the widget bounds.  All coordinates are expressed in local widget space.
 
    The color of the circle is determined by the widget scheme's 'foreground'
    color.
 
  Remarks:
    None.
