...as I noted at the end of my message.  My proposed solution is more a way
to make the raw event available so an extension library can be used to add
events without future changes to the X11 binding.

Another problem is XInput-specific. Once you call XISelectEvents (which is

This was what I meant by filtering; we'd be essentially replacing the
original event with a modified one that the core does recognize.
 Unfortunately it has just occurred to me we can't do this as it's
currently defined... bleh.

We need to give more thought to core extensibility.
