If media photons are turned on in global media settings, they're also 
turned on by default in all object medias in the scene.  The reason that 
photons work only with contained medias is probably that in an infinite 
media, a potentially infinite number of photons would have to be calculated 
and stored. The docs don't seem to mention this anywhere, though.
