Well, that's just one of the changes, but the most visible one.

In the past, the GIMP didn't work. Simply because the new device semantics state that if you grab an attached slave device, it will be detached and set to floating automatically until you ungrab again. Now, the GIMP always grabbed all extension devices, leaving you with nothing to actually control the cursor.

So, one of the changes I did over the last weekend was to get some versioning support into XI. The previous one was weak, as it didn't allow the client to tell the server what it supported. A new XQueryInputVersion() call in libXi can do that now, unless this call is issued we assume that the client supports XI v1.x.

For those clients that only support 1.x, we don't return the full device list but rather only the virtual core pointer, the virtual core keyboard and finally all floating extension devices. This essentially resembles a XI setup pre-MPX. As a result, the GIMP only tries to open extension devices that are already floating, leaving you with the ability to control your cursor normally.

This isn't a perfect solution, as some other semantics change too but it works alright so far.

Other than that, it was mainly cleanup. Including the transition of libXi to docbook xml based manpages, which should make it easier to actually write manpages now.

To update, pull inputproto, libXi and xserver.
