Then surely the extinction keyword should never be allowed to take a value
other than unity, and the conserve_energy feature should always be on, and
reflection_min should always be forced to take a value less than
reflection_max ...
I understand that 100% reflection would be the physically correct value, and
I'm sure that there is a good argument for making it independent of
reflection_max, but I'm just not sure that physical correctness is that
argument - it could be taken to apply a lot more widely than it does.
