  .SH PARAMETERS
  .TP \w'\f2left\fP\ \f2right\fP\ \ 'u 
  \f2left\fP, \f2right\fP
  Specify the coordinates for the left and right vertical clipping planes.
  .TP
  \f2bottom\fP, \f2top\fP
  Specify the coordinates for the bottom and top horizontal clipping planes.
  .SH DESCRIPTION
  \%\f3gluOrtho2D\fP sets up a two-dimensional orthographic viewing region.  
  This is equivalent to calling \f3glOrtho\fP with $ near ~=~ -1 $ and 
  $ far ~=~ 1 $.
