bug: cylinders faces get shadowed even though they are not in sight #27

I think there is a problem with the is_at_back function, because it's shadowing the inside of the cylinders, but they should have the face colors. I know there is something with is_at_back because when I modified the function to always return 0, it worked as intended.

Picture with actual is_at_back function:
