DESCRIPTION
Each of the mlib_GraphicsDrawLine_*() functions draws a line between (x1,y1) and (x2,y2).
Each of the mlib_GraphicsDrawLine_X_*() functions draws a line between (x1,y1) and (x2,y2) in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawLine_A_*() functions draws a line between (x1,y1) and (x2,y2) with antialiasing.
Each of the mlib_GraphicsDrawLine_B_*() functions draws a line between (x1,y1) and (x2,y2) with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the mlib_GraphicsDrawLine_G_*() functions draws a line between (x1,y1) and (x2,y2) with Gouraud shading.
Each of the mlib_GraphicsDrawLine_Z_*() functions draws a line between (x1,y1) and (x2,y2) with Z buffering.
Each of the other functions draws a line between (x1,y1) and (x2,y2) 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 point.
y1 Y coordinate of the first point.
z1 Z coordinate of the first point.
x2 X coordinate of the second point.
y2 Y coordinate of the second point.
z2 Z coordinate of the second point.
c Color used in the drawing.
c1 Color of the first point.
c2 Color of the second point, or the alternation color in the Xor mode.
a Alpha value for blending. 0 <= a <= 255.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
