  Message : Use both null and real renders for draw call perf. Introduce a "null" GL renderer for this specific benchmark, which does not do any work on drawArrays and drawElements. We could use the same kind of trick for buffer and texture updates, if we need it. This gives us a good baseline for comparing GL and D3D perf.
