:param int colors: (Optional) Number of colors to use. Most polygons would use two, one for
                    outline and one for fill. If you're not filling your polygon, set this to 1
                    for smaller memory footprint. (2)

    :param int|None fill: The color to fill the rectangle. Can be a hex value for a color or
                    ``None`` for transparent.
    :param int|None outline: The outline of the rectangle. Can be a hex value for a color or
                    ``None`` for no outline.
    :param int stroke: Used for the outline. Will not change the outer bound size set by ``width``
                    and ``height``.
