 * The resultant curve is no different than a (non-uniform) B-spline defined through control points. So all related limitations apply. See Sketcher CreateBSpline.
 * The B-splines created are always cubic (i.e. with degree 3).
 * The defined multiplicity may not always be respected:
 * For a periodic spline, the first knot (coincident with last) always has a multiplicity of 2.
 * For a non-periodic spline, the first and last knots always have a multiplicity of 4.
 * If the points just before and just after have multiplicities >=3, the piece between these two is fully continuous, and this (middle) point will only be constrained with point-on-object. If a knot is needed, consider using the insert knot tool.
