Annotations
Bezier curves are polynomial splines that use Bezier or Bernstein polynomials for interpolation purposes. It is a special case of the B-Spline curve with two knots.
degree shall be the degree of the polynomial used for interpolation in this spline.
knot shall be the sequence of distinct knots used to define the spline basis functions.
interpolation is fixed as "polynomialSpline".
isPolynomial is fixed as "true".
knotType is not relevant for Bezier curve segments.
