NAME
       StretchTool - tool for rotating components

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

DESCRIPTION
       StretchTool lets the user rotate components by direct manipulation.

PUBLIC OPERATIONS
       StretchTool(ControlInfo* = nil)
	      Create a new StretchTool.

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

       virtual void InterpretManipulator(Manipulator*)
	      CreateManipulator  detects  whether  the	user  clicked  on a component.	If not, it clears the editor's selection and returns a nil
	      manipulator.  If a component was hit, and if the component was not previously selected, then CreateManipulator clears  the  editor's
	      selection,  selects  the	component the user hit, and delegates manipulator creation and interpretation to it.  If the component was
	      the only selected component, it again delegates manipulator creation and interpretation to the component, but the selection is unal-
	      tered.   If the user clicks on one of many selected components, then CreateManipulator will delegate manipulator creation and inter-
	      pretation to the hit component without altering the selection.
