PendingBegin flag on XI_TouchMotionUnowned events?

[Chase Douglas]

Hi Daniel,

We currently have a mechanism for clients selecting for unowned events
to receive motion and finish events (through the PendingFinish flag).
However, how does a non-owner know that a TouchBegin event isn't owned
yet? Should we mutate TouchBegin events to TouchMotionUnowned and set a
PendingBegin flag?

P.S.: I've updated my inputproto branch on fdo to reflect changes I made
in my xserver branch for unowned events and pointer emulation.

Thanks!
