Bug Description

The pointer barrier event API we've patched in to libXfixes has moved upstream in Xserver 1.14. However, the API has changed.

The barrier events and pointer release API is now in the input lib, libXi as of version 1.6.99.1 . It should be reasonably easy to port to the new API: Peter Hutterer's blog post¹ describes how to use it. The main differences are that you need to add the barrier event mask to the XI event mask, rather than window event mask, and that it now uses generic events, so you need to allocate the event data before using it and free the event data after using it XGetEventData/XFreeEventData.

Plan of record for raring is to ship xserver 1.14, so fixing this is necessary to avoid a regression in Unity when we introduce 1.14.

1.14 is scheduled for March, with rc releases leading up to that. I'd like to see us include a 1.14 rc or git snapshot in early February so we have adequate testing time.
