Previously, Camera would keep track of which mobjects are supposed to be "static", so that it could generated their render groups once and not repeat unnecessarily. This had an awkward dependence where Scene would then need to keep track of which mobjects should and should not be considered static.
This update pushes that logic to the Mobject level, where it keeps track internally of whether it's being animated, has an updater, or can be moved around by the mouse.
