gluOrtho2D - define a 2D orthographic projection matrix

As shipped in IRIX 6.5.7. Unchanged since IRIX 6.5.

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.
