NAME
       MagnifyTool - tool for magnifying a portion of the GraphicView displayed in a viewer

SYNOPSIS
       #include <Unidraw/Tools/magnify.h>

DESCRIPTION
       MagnifyTool  lets  the  user  magnify  a portion a viewer's contents.  The user sweeps out a rectangular area with the MagnifyTool, and the
       viewer will magnify the area to occupy the entire screen, if possible.

PUBLIC OPERATIONS
       MagnifyTool(ControlInfo* = nil)
	      Instantiate a MagnifyTool.

       virtual Manipulator* CreateManipulator(
	  Viewer*, Event&, Transformer*
       )

       virtual void InterpretManipulator(Manipulator*)
	      CreateManipulator generates a DragManip with a RubberRect to provide visual feedback for specifying the rectangular area to be  mag-
	      nified.	InterpretManipulator  does not create a command; rather, it examines the DragManipulator's RubberRect and calls Magnify on
	      the viewer with the RubberRect's final coordinates.
