- renamed generic attribute "isValid" to "invalid" since BL_Shader already uses isValid. - Moved deprecation warnings from CValue - removed unused KX_Scene::SetProjectionMatrix and KX_Scene::GetViewMatrix - Added KX_Scene attributes "lights", "cameras", "objects_inactive", to allow access to objects in unseen layers (before the AddObject actuator adds them) - KX_Camera deprecated cam.enableViewport(bool) for cam.isViewport which can be read as well.
