TBoundingVolume ( const TBoundingVolume< TPayloadType, T, d >& Other

 Needed for tree of grids, should we have a more explicit way to copy an array of BVs to avoid this being public?

 IMPORTANT : (LWC) this API should be typed on Freal not T, as we want the query API to be using the highest precision while maintaining arbitrary internal precision for the acceleration structure ( based on T )
