I've no feeling how the particular regularization for the shaper
functions in xmatrix.c will behave, but at least typical smoothing
factors for RBFs, splines and other linear models rather follow a
logarithmic scale, so the range for useful smoothing factors
(slight...strong smoothing) can indeed span a few powers of 10.
