Default OnBodyGUI now uses default PropertyFields as suppied by UnityEditor. This means fields are drawn on nodes the same way as they are drawn in the inspector. out portPosition has also been moved to a static field. It is set automatically using the NodeEditorGuiLayout methods. Alternatively, you can alter it manually during your node GUI drawing.
