GLUORTHO2D()                                                      GLUORTHO2D()

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.
