Checks if this Path object joins smoothly with previous
        path/segment.  By default, this only checks that this Path starts
        moving (at t=0) in the same direction (and from the same positive) as
        previous stopped moving (at t=1).  To check if the tangent magnitudes
        also match, set wrt_parameterization=True.
