New algorithms calculating global properties on mesh data have been added: - BRepGProp_MeshCinert computes the global properties of polylines represented by a set of points; - BRepGProp_MeshProps computes the global properties of a surface mesh. Existing tool BRepGProp now automatically uses new algorithm for triangulation-only faces. By default, algorithm will use exact geometry objects (surfaces), when it is available (as before the patch); this behavior can be switched by a new flag UseTriangulation, forcing usage of triangulation instead of exact geometry when both defined.
