DESCRIPTION
Each of the mlibGraphicsDrawTriangle*() functions draws a
triangle with the vertices at (x1,y1), (x2,y2), and (x3,y3).
Each of the mlibGraphicsDrawTriangleX*() functions draws
a triangle in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlibGraphicsDrawTriangleA*() functions draws
a triangle with antialiasing.
Each of the mlibGraphicsDrawTriangleB*() functions draws
a triangle with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) ] c * a) / 255
Each of the mlibGraphicsDrawTriangleG*() functions draws
a triangle with Gouraud shading.

mediaLib Library Functions mlibGraphicsDrawTriangle(3MLIB)
Each of the mlibGraphicsDrawTriangleZ*() 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.

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 MLIBSUCES if successful.
Otherwise it returns MLIBFAILURE.
