The new polynomials +are anisotropic tensor products of Lagrange polynomials on the points of a +Gauss--Lobatto quadrature formula. This change leads to different entries in +the matrices and constraints, for example, but as the resulting polynomial +space spans the same polynomials, no change in accuracy should be expected. +
