1) Add empty constructor for Poly_Triangulation(), 2) Add Poly_Triangulation::HasGeometry() method to check that triangulation has any geometry. 3) Add possibility to cache bounding box in Poly_Triangulation and use it later in case of empty triangulation. 4) Add Poly_Triangulation::MinMax() to extends input box with bounding box of triangulation. 5) Add Poly_Triangulation::UpdateCachedMinMax() to cache min - max range of this triangulation with bounding box of nodal data. 6) Add virtual Poly_Triangulation::computeBoundingBox() to calculate bounding box of nodal data. 7) Update BRepBndLib::Add/AddOptimal/AddOBB algorithms to check empty triangulation and use cached box in this case. 8) Update BRepGProp::roughBary/surfaceProperties/volumeProperties to skip empty triangulation. 9) Remove additional myBox from RWGltf_GltfLatePrimitiveArray and some hack to save this box as nodes of base Poly_Triangulation. 10) Cache min-max range from JT file during its parsing
