WINDOW defines the dimensions of the current graphics viewport window.
 
WINDOW [[SCREEN] (x1!,y1!)-(x2!,y2!)]
 
Usage Notes
    ■ The WINDOW statement allows the user to create a customized coordinate
      system to draw lines, graphs, or objects without being constrained by
      the graphics viewport physical coordinate values and orientation.
    ■ WINDOW defines a coordinate system that is mapped to the physical
      coordinates of the viewport. All subsequent graphics statements use
      the window coordinates and are displayed within the current
      viewport.  The viewport may be the entire screen or a clipping area
      defined in physical coordinates by the VIEW statement.
    ■ A WINDOW statement with no arguments, or a RUN statement, disables
      the window coordinate system.
