    """pygame.numpyarray.array_colorkey(Surface): return array

    copy the colorkey values into a 2d array

    Create a new array with the colorkey transparency value from each
    pixel. If the pixel matches the colorkey it will be fully
    tranparent; otherwise it will be fully opaque.

    This will work on any type of Surface format. If the image has no
    colorkey a solid opaque array will be returned.

    This function will temporarily lock the Surface as pixels are
    copied.
