Wasn't ever used by anything and not that well defined anyway. So they all just passed it on to the drivers. And then sometimes the driver version was called and sometimes the IMaterialRendererServices version. So now everything just calls the driver - all places which need it have access to the driver anyway. Also made the driver version non-virtual for now. If someone actually really needs this for some reason I can add it back as virtual function directly in IVideoDriver. But I doubt it - the interface was hardly accessible until recently and originally only meant for internal stuff. GLES version still to do, but checked them earlier and they also just do nothing with it. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6486 dfc29bdd-3216-0410-991c-e03cc46cb475
