I chose recursion limit 10 because less seemed to not cover the corners (for
instance under the soffit). Part of the problem I suppose is that I chose to
only have reflected light in the radiosity pass. Perhaps lower the recursion
limit and add some direct lighting in the radiosity calculation?

Brightness of 2 came out of rendering a dark scene and needing it to be
lighter. Is the "limit" 1, (is 2 super-bright like rgb 2,2,2?).
