Each of the mlib_GraphicsDrawPoint_*() functions draws a point at (x,y) in color c.
Each of the mlib_GraphicsDrawPoint_X_*() functions draws a point at (x,y) in Xor mode as follows:
data[x,y] ^= c ^ c2
Each of the mlib_GraphicsDrawPoint_B_*() functions draws a point at (x,y) with alpha blending as follows:
data[x,y] = (data[x,y] * (255 - a) + c * a) / 255
Each of the functions takes some of the following arguments:
buffer
x
y
c
c2
a
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
