bge bugfix: [#34517] 2D Filter causes mouselook script drifting effect (patch by Daniel Stokes - Kupoman)
Fix for 2.66a

""We can't pass the results of canvas->GetViewPort() directly because canvas->SetViewPort() does some extra math""
Bug introduced during 2.65 series in the refactor to use canvas->SetViewPort instead of direct opengl calls for viewport
