Correct wireframe for quadratic elements in multi-core mode
Wireframe (or surface with wireframe) representation does not work with quadratic elements when in multi-core mode. The cause is that quadratic wireframe is not supported when geometry is shipped from server to client (which is implicitly the case for multi-core mode). See bug 10676, the bug that originally implemented correct quadratic wireframes, for more details on this unimplemented case.
