[Paraview] Singleton vtkObject multiple SMProxies

OK. It doesn't work. I misread/understood the Adaptiveoption::getProxy() stuff..

Another question instead :
in vtkSMProxy, suppose I attached to vtkObject::ModifiedEvent and tell the proxy to update all values from the vtkObject - which call will tell the proxy that all values need to be reloaded (MarkAllPropertiesAsModified will push them to vtkObject, but I don't see one for pulling).
