I've been thinking for quite some time now that the use of the ambient term in
radiosity-only scenes is no good. When one wants to create a light source in a
radiosity-only scene, technically the classic lighting's ambient mechanism does
the required thing, but the intention is *far* away from the concept implied by
that parameter's name. And it keeps causing trouble.

If I'm asked, there should be a separate "emission" parameter, with the whole
"ambient" mechanism turned off in radiosity scenes.

After all, the original intention of the ambient term, and its most common use
in non-radiosity scenes, is to approximate diffuse illumination - which is
*exactly* what radiosity is intended to model more realistically.
