Also added another callback sent at backend initialization: DefGfxMessageProc(). This function will handle all messages that the backend doesn't understand. It is implemented by the engine.

Oops. Didn't answer the question. :)

There isn't any message queue, and no message pump is required. It has the interface similar to window's SendMessage(), not PostMessage().
