From Wang Rui, "Some developers report that the osgviewerMFC example is broken in 3.2, in which depth test is not enabled by default so all models loaded look awkward. I submit this patch to make it work again. I haven't gone deep to check why previous example goes wrong in newer version but I believe the problem was because the newly created camera object missed some important global statesets before set as the main camera."
