I couldn't find this on Rune's list and I can't figure out what I am
doing wrong with this one, so here we go again...
So, this also appeared when I remade MegaPov scenes to POV 3.5. There is
strange behaviour when I try to render objects that have some part of
the rgb definition over 1. In MegaPov I got expected results with this,
but POV 3.5 betas make the colors go oddly wrong; like I used byte
variable to store the colors and then set them to values over the range.
Scene below describes this bug. For what I have understood, this scene
should render similarly whether the variable "showBug" is true or false.
