Thanks, Mike!

It /should/ be glass; see below for the relevant parameters. I used the
two-pass method of rendering a half-size no AA version to generate the
photon & radiosity files.

I've been polishing up the Chain() macro & have written some user
documentation for it. Do you have any suggestions?
