[Xcb] xcb-xinput -- raw motion events

[chris at demorecorder.com]

Hi Ingo,

For XInput, I suggest that you use the current HEAD from git 
   http://cgit.freedesktop.org/xcb/proto
   http://cgit.freedesktop.org/xcb/libxcb

The reason is that in the previous official version, xinput is not officially supported 
and contains a lot of bugs and missing pieces, most of which are fixed in the git-HEAD.

That may be the reason why you weren't able to figure it out.

Hope this helps,

Chris
