While they may be only 'visual' in terms of influence/cell grid, they all do update CenterPosition, which is essentially the actual world position of the actor. 'Visual' would imply that it only affects the position where the actor is drawn, which is inaccurate. Furthermore, using the term 'Visual' here would make naming future methods/properties related to visual interpolation unnecessarily complicated, because that's where we might need a real 'Visual(Only)Position'.
