fix missing *_STATECHANGE in *UpdateViewportOffset for radeon, r200 and r300 (reported by Jim Duchek). Fix some potential problems with strict-aliasing with r200 and radeon drivers in *UpdateViewportOffset, *PolygonOffset and *UpdateWindow functions (some compiler warnings about strict-aliasing remain in the codegen vertex code, and there may be more problems unnoticed by the compiler).
