DESCRIPTION
     Each of the mlib_GraphicsDrawTriangle_*() functions draws  a
     triangle with the vertices at (x1,y1), (x2,y2), and (x3,y3).


     Each of the mlib_GraphicsDrawTriangle_X_*() functions  draws
     a triangle in Xor mode as follows:

           data[x,y] ^= c ^ c2



     Each of the mlib_GraphicsDrawTriangle_A_*() functions  draws
     a triangle with antialiasing.


     Each of the mlib_GraphicsDrawTriangle_B_*() functions  draws
     a triangle with alpha blending as follows:

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



     Each of the mlib_GraphicsDrawTriangle_G_*() functions  draws
     a triangle with Gouraud shading.

mediaLib Library Functions       mlib_GraphicsDrawTriangle(3MLIB)



     Each of the mlib_GraphicsDrawTriangle_Z_*() functions  draws
     a triangle with Z buffering.


     Each of the other functions draws a triangle with a combina-
     tion  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.


     x1         X coordinate of the first vertex.


     y1         Y coordinate of the first vertex.


     z1         Z coordinate of the first vertex.


     x2         X coordinate of the second vertex.


     y2         Y coordinate of the second vertex.


     z2         Z coordinate of the second vertex.


     x3         X coordinate of the third vertex.


     y3         Y coordinate of the third vertex.


     z3         Z coordinate of the third vertex.


     c          Color used in the drawing.


     c1         Color of the first vertex.

mediaLib Library Functions       mlib_GraphicsDrawTriangle(3MLIB)



     c2         Color of the second vertex,  or  the  alternation
                color in Xor Mode.


     c3         Color of the third vertex.


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


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