Fixed regression of SelectMgr_ViewerSelector::SetPixelTolerance(). Removed redundant myToUpdateTolerance flag. 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.
