Generally the piecewise linear option should be selected. However, if
the boundaries are sampled on a very fine scale (a few wavelengths)
then the curvilinear option produces a smoother fit. That in turn
improves the results obtained with geometric ray tracing. The
curvilinear option was implemented to treat fine scale scattering
effects.
