The magic extra library is a non-solution. The user implementing event handling doesn't know what GLX/EGL is doing, so you can't rely on them using the magic extra library. This implementation is basically the "fix events somehow" option in that cited email: the new events have the multiplexing token (the eid field), and this is the code for getting those events to the code that registered for the event.
