SelectMgr_AxisIntersector::raySegmentDistance() - fixed usage of SquareModulus() instead of Modulus().
SelectMgr_ViewerSelector::TraverseSensitives() now skips both BVHSubset_2dPersistent and BVHSubset_3dPersistent relying on Camera.
AIS_ViewController::handleXRMoveTo() now uses interface for picking by Axis explicitly
instead of emulating axis by point picking.
