HI Wojtek, Excellent detective work. I'll have to raise my hand as the culprit of the change to CullVisitor::apply(Camera), done is response to a discussion between Mathias Froehlich and myself about inheritance of settings. I believe the inheritance of settings is now correct, but obviously in

Hi Robert, Since I think the actual rules of inheritance of settings are correct, and things worked before because of bug in the inheritance of settings, so its a matter of either changing the defaults in CullSettings so that less of the inherited state comes down into the local Camera, or we
