       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
       function 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
       hardware, 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
       threeDkit/ 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

       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/
       subdirectory. As of this writing, svgalib-1.2.12.tar.gz is the latest
       version 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.
