Rik Hemsley f65ca70e0b Fixed maximisation. Now kwin really does avoid windows which ask 
to be avoided. It also updates nicely. Just move kicker from the
bottom to the left, say, and open a new window. It doesn't cover
kicker. Maximise. Still doesn't cover. Seems to work, then.

\class WindowWrapper client.h
\brief The WindowWrapper class encapsulates a client's managed
window.
There's not much to know about this class, it's completley handled by
the abstract class Client. You get access to the window wrapper with
Client::windowWrapper(). The big advantage of WindowWrapper is,
that you can use just like a normal QWidget, although it encapsulates
an X window that belongs to another application.
In particular, this means adding a client's windowWrapper() to a
QLayout for the geometry management. See StdClient for an example
on how to do this.
