Well, right now photon mapping only does specular and refractive caustic
lighting, while 'radiosity' does indirect diffuse lighting... so right
now they are pretty orthogonal features, so you can use them together
without problems.

Sorry, but photons don't work right with area lights... eventually they
will... I haven't taken the time to program that part yet. ;-)
All lights are currently treated like point lights.
