Is there a reason you can't use X11DRV_register_event_handler?

I didn't find any guarantee that returned event type will be small 
enough to fit into the handlers table. In my testing
event_base returned by XFixesQueryExtension was equal to 83.

I can change the patch to use X11DRV_register_event_handler. I don't 
know if it's correct.

Thanks,
Piotr

It will fit, 128 is an X protocol limit.
