    Seeing this has reminded of something I didn't understand when I looked
at photons - What does ignore_photons do ? From the docs, it seemed to me
that it instructed MegaPOV to completely ignore photon interactions with the
object it's declared in, but then it recommended using it in glass or other
transparent objects - surely transparent objects are exactly those that you
want the photons to interact with, no ?
