Message:

substantial work to correctly handle higher order polynomial.
conversions between the internal fitting model (R = sum (Aij x^{i y}j))
and the header representation were incorrect: they did not correctly
handle the shift to the CRPIXi value (ie, x -> (x - xo)). i fixed this
by making the fit explicitly work on the fit to the tangent-plane
coordinates, instead of fitting corrections, and calculating the correct
change of polynomial coefficients. this is not as simple as it seems at
first glance: the header version of the coefficients does not have a
zero-order term, and instead has the CRPIX value. to convert from one to
the other requires solving the equation L(Xo,Yo),M(Xo,Yo) = (0,0). I do
this using the Newton-Raphson method.
