10/20/2021         : x is no longer unscaled/scaled when using the callback
                     because doing so can change x, and alter the course of
                     the minimization. The callback uses a temporary copy of
                     an unscaled x. (contributed by Andrew Nelson)

                     Warning: API changes: refined stopping criterions (xtol,
