Added rotation and zoom splines to note columns, with the help of a couple new classes. Reorganized args to NoteDisplay functions into helper structures. Made splines have 3 modes controlling their behavior. Hold twisting is now handled by an AA rotation and hold drawing in general is now more complex.
