This patch implements an XProperty named _KDE_NET_WM_OPAQUE_REGION
which gives the compositor the information which part of a window
is opaque although it is an ARGB visual. The basic ideas are from
http://www.mail-archive.com/wm-spec-list@gnome.org/msg00715.html
Additionally the patch makes kwin use this information to do a better
clipping in Scene::paintSimpleScreen which should result in a higher
performance.

This commit merges the two signals clientClosed() and unmanagedClosed() to windowClosed() which
is now provided by Toplevel.
The approriate slots in effects.h and effects.cpp were merges as well, since they did the
same.
The direct method calls of the method windowClosed() in SceneOpenGL and SceneXRender were
removed and are now connected to the appropriate signal in windowAdded().
The method windowGeometryShapeChanged() from the class Scene is now a slot. It is now connected to the signal geometryShapeChanged() which is sent from Toplevel instances Client and Unmanaged.
All direct method calls were deleted.
In order to notice when the geometry changes a new signal is
added to toplevel and both Unmanaged and Client connect all their
signals which are emitted whenever the geometry changes in some way
to this new signal.
Shadow connects to the signal and updates the quads and region
whenever the size changes.
The Shadow is clearly an aspect of the compositor. Therefore the
Shadow has to be owned and controlled by the Scene::Window.
Nevertheless Toplevel needs to know about the Shadow cause of reading
the property.
Unmanaged needs to repaint the complete geometry including shadow
when it ends compositing. Therefore we need to track the shadow
passing to deleted correctly. Disadvantage: when turning off
compositing the shadow is kept. Need to solve in a better way!
Client and Unmanaged use a signal to notify that they are about to be closed.
The EffectsHandlerImpl is connected to those signals and emits the appropriate
windowClosed signal to which the effects are connected.

this code is buggy right now, but I promise to squash the bugs by the 19th :)

means any GPL). Decoration clients will come later.

The ugly side effect of this is that there are tons of static_casts in the code now... maybe it
would be better to add effectImpl() convenience method and use that?
