X Gesture Extension protocol - draft proposal v1

[Nicolai Haehnle]

I admit to not really having read everything in this thread, but I
feel that there is a point here that requires some more driving home.

Putting on my hobby game developer's hat, "very minimal latency" is
not good enough.

I don't have the hardware right now, but if I eventually get it and
toy around with it in a game context, I really want _zero_ latency.
Anything greater than that is unacceptable (obviously, some latency
cannot be avoided; but games really want to see input events as soon
as technically possible). If gesture recognition happens on the
server, then at the very least, you need to provide a way to disable
it over the windows that I care about.
