Gosh, if we're so evil and sneaky, perhaps you can enlighten us with a 
way to do it that is transparent to applications?  Requiring the 
application to magically know that it needs to process some event and 
send it to the GL library is a non-starter.  DRI is a driver 
implementation detail that the application cannot know about.
