[Radiance-general] time need independent from number of faces?

The ray-tracing time in Radiance is only weakly affected by the
number of surfaces, thanks to the octree spatial subdivision. I
would expect the calculation time to increase with representation,
but very slowly. (That's why you can render scenes with millions of
surfaces.)
