+                test did not take into account the estimated extent. The hit point
+                may be outside the actual extent of the surface.
+ EstimatedHorizontalPlane: Hit test found a plane, but one for which we have no 
+                           anchor.
+ Feature Point: Hit test found a point that the AR session believes is part of a
+                continuous surface. This surface may not be horizontal.
