That's not necessary, as without classic light sources these values don't have
any effect anyway (well, maybe a *tiny* bit more computing time).

They should definitely be non-zero for materials to work in non-radiosity-lit
scenes, as they will have to simulate highlights from the classic lights, which
we can't see otherwise.


Ideally, there should be *some* connection between these values and the
reflectivity of the material (and likewise between the roughness or
corresponding phong parameter, and the blurriness of reflectivity in case
micronormals are used), though I'm not sure how exactly these should be
related.
