Bug warning:

You may run into problems with photons in media.  I just noticed a bug where
media is attenuated at the wrong time, so the last section of media might
not be calculated.  Try to have an empty space between your media-containing
object and the surface that gets hit by photons to make sure things get
computed correctly.  Photons on the surface of the media-contianing object
or on objects within the media may not get attenuated.
