This adds an internal _clutter_stage_get_active_framebuffer function that can be used to get a pointer to the current CoglFramebuffer pointer that is in use, in association with a given stage. The "active" infix in the function name is there because we shouldn't assume that a stage will always correspond to only a single framebuffer so we aren't getting a pointer to a sole framebuffer, we are getting a pointer to the framebuffer that is currently in use/being painted. This API is now used for culling purposes where we need to check if we are currently painting an actor to a framebuffer that is offscreen, that doesn't correspond to the stage.
