unless I've missed something you don't need Polynomial2DInterpolation
as you can obtain quadratic interpolation using the class
CubicInterpolation with DerivativeApprox::Parabolic.
Then it might be too exoteric, but it would benice to generalize
Interpolation2D to accept a policy (x_first or y_first) and (possibly)
different factories for the x and y axis, so that your new
Polynomial2DSpline (and the old BicubicSpline, BilinearInterpolation
too) would just become typedefs
