What is the difference between the different .Plane-TrackableTypes? The definitions seem pretty vague to me. For instance, PlaneEstimated? Like, if it isn't actually a plane, what is it, and how does it work? Since there is already PlaneWithinInfinity, which to me, sounds almost the same. Also, the difference between PlaneWithinPolygon and PlaneWithinBounds? Lastly, is there a logic behind using just TrackableType.Planes? Should this be used alone, or is it just to get all the possible plane trackable types in the ARRaycastHit?
