DESCRIPTION
Each of the mlib_GraphicsDrawPolygon_*() functions draws a polygon enclosing (x1,y1), (x2,y2), ..., and (xn,yn).
Each of the mlib_GraphicsDrawPolygon_X_*() functions draws a polygon in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawPolygon_A_*() functions draws a polygon with antialiasing.
Each of the mlib_GraphicsDrawPolygon_B_*() functions draws a polygon with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the mlib_GraphicsDrawPolygon_G_*() functions draws a polygon with Gouraud shading.
Each of the mlib_GraphicsDrawPolygon_Z_*() functions draws a polygon with Z buffering.
Each of the other functions draws a polygon 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 the array of X coordinates of the vertices.
y Pointer to the array of Y coordinates of the vertices.
z Pointer to the array of Z coordinates of the vertices.
npoints Number of vertices in the arrays.
c Color used in the drawing, or pointer to array of colors of the points in the case of Gouraud shading.
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.
