t None, must be a four-tuple (x1, y1, x2, y2)
            defining a rectangle in which to clip the path.
        snap : None or bool, optional
            If True, snap all nodes to pixels; if False, don't snap them.
            If None, snap if the path contains only segments
            parallel to the x or y axes, and no more than 1024 of them.
        stroke_width : float, optional
            The width of the stroke being drawn (used for path snapping).
        simplify : None or bool, optional
            Whether to simplify the path by removing vertices
            that do not affect its appearance.  If None, use the
            :attr:`should_simplify` attribute.  See also :rc:`path.simplify`
            and :rc:`path.simplify_threshold`.
        curves : bool, optional
            If True, curve segments will be returned as curve segments.
            If False, all curves will be converted to line segments.
        sketch : None or sequence, optional
            If not None, must be a 3-tuple of the form
            (scale, length, randomness), representing the sketch parameters.
