I doubt that it would be assigned to fatal error status, and instead have a
default, and just issue a warning.
As it is, you can have scenes with no light and no camera, and they still
"render"...

I think that after all of the hair-yanking, brain-hurting effort that's been put
in over the years to get the gamma handling of POV-Ray onto solid footing, that
clipka simply wants people to be cognizant that working with an assumed_gamma of
1.0 is the way to go, and all other scene "fixes" can be addressed by some other
mechanism.

I couldn't find the particular thread where he explains the many pitfalls of
improperly using gamma != 1.0, but I can assure you that he has expostulated
passionately and extensively on the topic.
