DESCRIPTION
     Each of  the  mlib_GraphicsDrawTriangleFanSet_*()  functions
     draws a set of triangles with vertices at {(x1,y1), (x2,y2),
     (x3,y3)}, {(x1,y1), (x3,y3), (x4,y4)},  ...,  and  {(x1,y1),
     (xn-1,yn-1), (xn,yn)}.


     Each of the mlib_GraphicsDrawTriangleFanSet_X_*()  functions
     draws a set of triangles in Xor mode as follows:

           data[x,y] ^= c ^ c2



     Each of the mlib_GraphicsDrawTriangleFanSet_A_*()  functions
     draws a set of triangles with antialiasing.


     Each of the mlib_GraphicsDrawTriangleFanSet_B_*()  functions
     draws a set of triangles with alpha blending as follows:

           data[x,y] = (data[x,y] * (255 - a) + c * a) / 255



     Each of the mlib_GraphicsDrawTriangleFanSet_G_*()  functions
     draws a set of triangles with Gouraud shading.


     Each of the mlib_GraphicsDrawTriangleFanSet_Z_*()  functions
     draws a set of triangles with Z buffering.


     Each of the other functions draws a set of triangles with  a
     combination  of  two or more features like antialiasing (A),
     alpha blending (B), Gouraud shading  (G),  and  Z  buffering
     (Z).

PARAMETERS
     Each of the functions takes some of the following arguments:

     buffer     Pointer to the image into which the  function  is
                drawing.

     zbuffer    Pointer to the image that holds the Z buffer.


     x          Pointer to array of X coordinates of the points.


     y          Pointer to array of Y coordinates of the points.


     z          Pointer to array of Z coordinates of the points.


     npoints    Number of points in the arrays.


     c          Color used in the drawing, or pointer to array of
                colors of the points in the case of Gouraud shad-
                ing.


     c2         Alternation color.


     a          Alpha value for blending. 0 < a < 255.


RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
