Subject: * Adds Normal to the fields returned by the Physics Raycaster * Fixes
 recognizing when a sit target is and isn't set. * * 1. Vector3.Zero. * * 2.
 Orientation: x:0, y:0, z:0, w:1 - ZERO_ROTATION * * (or) Orientation: x:0,
 y:0, z:0, w:0 - Invalid Quaternion * * (or) Orientation: x:0, y:0, z:1, w:0 -
 Invalid mapping, some older objects still exist with it
