This provides finer control as to when the changes get constructed and initial stitching is performed. These is needed by certain processes, notably decomposition and reconstruction. By default, the mesh still performs all these operations on a "normal" read-construction. A flag has to be passed explicitly to the constructor in order to prevent the post-construction steps.
