[PATCH inputproto 3/4] Add XIPointerEmulated for emulated events

[Peter Hutterer]

From: Daniel Stone <daniel at fooishbar.org>

The XIPointerEmulated flag on pointer events means that the event was
emulated from a smooth-scroll or touch event to support legacy events,
and the client may ignore this if it is listening to the other events.
