- Ellipse => Cubic Bézier: used by rasterizer and PDF targets (see Maisonobe paper)
NB: GL5 means a Gauss-Legendre n=5, which is an numerical approximation as there is no analytical solution. Chebyshev is a converging way to approximate a function by an n=10 degree polynomial. It uses the bisection method as well to determine the polynomial points.
