Detailed Description

DtBoxUpdater is an update makes sure points for a box conform to that of a box and will update them if they are not.

It will also ground clamp and level the orientation of the box, thus this updater is only used for 2D Overlay box (polygon) objects and used by the Dt2DBoxFacade. It should not be used for extruded polygon models
