Callback method is fine but this is certainly not the way to do it.
First create a KX_KetsjiEngine::RegisterOnResizeCallback(function,param)
so that each module can register its callback function. When the
viewport is resized, the BGE gets a ghost notification (I guess) and
calls KX_KetsjiEngine::OnResize(), which walks through the registered
callback functions and calls them one by one. 

KX_KetsjiEngine::OnResize()
   for (i=0; i<callbacks.size(); i++)
      callbacks[i]->function(viewport, callbacks[i]->param);
