       gl_trisetdrawpoint - set	a triangle drawing function

       #include	<triangle.h>

       void  gl_trisetdrawpoint(void  (setpixelfunc) (int x, int y, int	color)

       If this function	is called with setpixelfunc non-zero, then  the	 func-
       tion  setpixelfunc is used from there after to draw each	pixel (instead
       of the usual direct screen buffer writes).

       This function need never	be used, except	if you want to	use  your  own
       pixel  drawing function for extra effects. If you use this feature, you
       can be assured that none	of the triangle	routines will access the hard-
       ware, enabling portability to other environments.

       Beware,	these  functions are not a direct part of the svgalib library.
       Instead their source is part of svgalib and can be found	in the threeD-
       kit/  subdirectory of the original svgalib distribution.	However, it is
       not installed in	the system by default, s.t. it is  unclear  where  you
       can find	it if your svgalib was installed by some linux distribution.

       In  case	 of  any such problem, simply get an svgalib distribution from
       the net.	Yo don't need to install it. Just make in the threeDkit/  sub-
       directory. As of	this writing, svgalib-1.2.12.tar.gz is the latest ver-
       sion  and  can  be   retrieved	by   ftp   from   at
       /pub/Linux/libs/graphics	 and at /pub/linux/sources/libs
       which will most probably	be mirrored by a site close to you.

       The functions are defined in the	tri.o and triangl.o

       The functions are defined in the	tri.o and triangl.o  files  (or	 their
       resp. sources) which you	must link to your program.
