  Z-buffer
  
     <graphics> An array used to store the maximum Z coordinate
     of any feature plotted at a given (X, Y) location on the
     screen, used for hidden line removal in a 2D rendering of a
     3D scene.  The Z axis is perpendicular to the screen with
     values increasing toward the viewer so that any point whose Z
     coordinate is less than the corresponding Z-buffer value will
     be hidden behind some feature which has already been plotted.
