Each of the mlib_GraphicsDrawPolyline_*() functions draws a polyline connecting (x1,y1), (x2,y2), ..., and (xn,yn).
Each of the mlib_GraphicsDrawPolyline_X_*() functions draws a polyline in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawPolyline_A_*() functions draws a polyline with antialiasing.
Each of the mlib_GraphicsDrawPolyline_B_*() functions draws a polyline with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the mlib_GraphicsDrawPolyline_G_*() functions draws a polyline with Gouraud shading.
Each of the mlib_GraphicsDrawPolyline_Z_*() functions draws a polyline with Z buffering.
Each of the other functions draws a polyline with a combination of two or more features like antialiasing (A), alpha blending (B), Gouraud
shading (G), and Z buffering (Z).
Note that the mlib_GraphicsDrawPolyline_*() functions are aliases of the mlib_GraphicsDrawLineStripSet_*() functions.
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 shading.
c2 Alternation color.
a Alpha value for blending. 0 <= a <= 255.
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
