[SRU] Fix problem in Qt dragging when all of the window target has been shaped out for input

Bug #987855 reported by Albert Astals Cid on 2012-04-24

Bug Description

In Unity-2d we use input shaping to define which part of our window accepts user input, unfortunately Qt did not have support for that feature when dragging from a Qt applications resulting in impossibility of dragging in applications like Mumble or KMail.

We fixed this issue with a patch to Qt (that was accepted upstream) but sadly that patch had a bug when all of the window is shaped to not accept user input.

This means we need a new patch (still being reviewed upstream) otherwise when the launcher is hidden dragging from those applications still does not work.

The upstream patch can be found at https://codereview.qt-project.org/#change,24361 (it includes unit tests this time so it should be the final one)
