This module provides the possibility to dump rendered graphics into
vector postscript files using the feedback buffer rendering 
mechanism of OpenGL. It is in a beta state and possibly will remain
there because it is not that easy to map all the OpenGL functionality
to Postscript. It should reasonably well render graphics which remains
in the limits of the OpenGL features used by the other gltools parts.


This code would not exist if Mark Kilgard wouldn't have placed his
rendereps sample code onto the net, and if there would not exist 
Frederic Delhoume's free gouraudtriangle postscript code.
From Mark's code, handling of lines and polygons has been taken.
String handling is new.

void glepsDumpUnSorted(glWindow w, FILE *file);

/*

  Create vector postscript dump using the feedback buffer
   mechanism, but without hidden surface removal.
   */


/*\func{glepsDumpSorted}*/
void glepsDumpSorted(glWindow w, FILE *file);
/*
  Create vector postscript dump using the feedback buffer
  mechanism, with hidden surface removal based on sorting
  the feedback buffer before the dump.

/*\func{glepsSetOutputFormat}*/
void glepsSetOutputFormat(char * coord_fmt, char *color_fmt);
/*
  Set the output format for floating point numbers  (different for coordinates and colors)
  in the postscript file.
  (The more accurate the format, the longer the file...). There have to
  be a trailing spaces both formats.
