NAME
       gluOrtho2D - define a 2D orthographic projection matrix


C SPECIFICATION
       void gluOrtho2D( GLdouble left,
			GLdouble right,
			GLdouble bottom,
			GLdouble top )


PARAMETERS
       left, right Specify  the	 coordinates  for the left and right vertical
		   clipping planes.

       bottom, top Specify the coordinates for the bottom and top  horizontal
		   clipping planes.

DESCRIPTION
       gluOrtho2D  sets	 up  a	two-dimensional	 orthographic viewing region.
       This is equivalent to calling glOrtho with near=−1 and far=1.
