public void get_size (out float width, out float height)
This function tries to "do what you mean" and return the size an actor will have.
If the actor has a valid allocation, the allocation will be returned; otherwise, the actors natural size request will be returned.
If you care whether you get the request vs. the allocation, you should probably call a different function like get_allocation_box or get_preferred_width.
