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.

and skip damage handling if the window is already completely damaged.
Also avoid QRegion handling during this since we know about the rects and
the region is handled when adding the damage anyway.
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.
Since the funtionality of TopMenu did no longer work in KDE4 this feature was
removed from Workspace. Every reference to it was removed as well as commentaries
and documentation.

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.
For a complete documentation of new functionality refer to:
http://community.kde.org/KWin/Shadow
The current implementation includes a new Shadow class and Toplevel
holds a pointer to an instance of this class. The Shadow class reads
the data from the X11 Property. There is one extended class located
in SceneOpenGL to render the shadow.
Compositor is adjusted to include the shadow region into the painting
passes.
Implementation for XRender still missing and Shadow needs to respond
to size changes of the Toplevel to update cached shadow region and
WindowQuads.
in TopLevel::isOnCurrentActivity().
KActivityConsumer makes a blocking DBUS call to kded, which if done while
we're holding an X server grab can result in a deadlock if kded is blocked
waiting on a reply from the X server.

As this is a bigger commit I will wait with backporting to 4.3 for something about two or three weeks and will only backport if nobody yells.

in the naive hope that it won't cause any real problems. Maybe effects doing
window previews should get API to suspend unredirect though.

- the NormalState/IconicState things in ICCCM need to match exactly
the real mapping state, so ensure that, no matter how superfluous that is
- extend the option for having live window previews either for all
windows or for only all shown windows (default)

Which means move this inline code to non-inline in the .cpp, after the

There's also a kwineffects library now, containing the effects API, which makes it possible to write
third-party effects.
API isn't complete yet and for now just two effects have been converted but I'm working on it :-)

It may fail (or "fail") if the window is not mapped or if the geometry
doesn't match, both of which may happen due to the asynchronous
nature of X.
