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.
Each of the mlib_GraphicsDrawTriangle_Z_*() functions draws a triangle
with Z buffering.
Each of the other functions draws a triangle 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.
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 MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
