Bug #2338

Numerical instability in roughness calculations

Appeared in current release, in release 14 is absent.

Use attached project, run simulation and play with roughness/thickness of intermediate layer.
For thickness > 100nm and roughness !=0.0 simulated image explodes.

In release 14 we see normal scattering from roughness profile.
