This patch reduces the number of QRegion and WindowQuadList operations
by drawing the opaque and translucent parts of the window within the
same bottom to top pass.

By default clip is enabled. This means that if the thumbnail would
overlap the "parent" window, it does not get rendered at all. If set
to false it will always be rendered. This is required for window strip
where the complete screen width is used, so overlap does not matter.
A new QML item "ThumbnailItem" is registered to the TabBox. The
C++ implementation finds the EffectWindow of the TabBox and adds
itself to the EffectWindow.
While rendering the EffectWindow the information for all registered
ThumbnailItems are extracted and the thumbnail is rendered on top
of the EffectWindow.
This has obvious limitations like you cannot put other QML items
on top of the thumbnail. Nevertheless it works well enough to
be a possible replacement for e.g. BoxSwitch effect.
When compositing is disabled an icon is rendered instead of the
Thumbnail.
One TabBox Layout inspired by BoxSwitch Effect is added. For the
KCM small pre-rendered items are used.

QElapsedTimer doesn't have a constructor that initializes the
private members. This means that calls to isValid() will depend
on uninitialized data when the timer has never been started.
elapsed() and restart() will also use and return values
computed from uninitialized data.
This fixes several valgrind errors.
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.

Instead of calculating the elapsed time from epoch clock, using
a QElapsedTimer as well as reusing the timer object instead of
creating a new one in the scene each frame.

So far we have not used the information that damage events are window-specific, resulting in the
behavior that we repainted the damaged area although it might be hidden behind another window.
E.g. the CPU-Monitor plasmoid is almost all day occluded by a browser etc. and before this patch
we have been repainting the appropiate area every time the plasmoid has been updated.
Thx to Thomas Lübking for optimizing the patch.

All the functionality of Overlay Window is moved to its own class
OverlayWindow. It is created and owned by class Scene, since almost
all function calls are called from this class.
REVIEW: 101866
The class Scene now inherits from QObject and has the Q_OBJECT macro. The inheriting classes SceneOpenGL and SceneXRender are provided with the Q_OBJECT macro. Now it is possible to use signals and slots and replace direct method calls.
Removes the last bits of the self-check at compositing startup.
It seems like they were only added to XRender because they were
in OpenGL and there they are not available for quite some time.
Also removes the now obsolete disable functionality checks from UI.

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.
It is not always required to do a full repaint in each frame. E.g. in sliding popups the repaint areas are known and tracked.
This change reduces the painting overhead to just the window area.
Nevertheless I consider this change as experimental and will revert the commit in case it introduces rendering glitches.
Other effects which are good candidates for this flag is wobbly windows, magic lamp, minimize or in general all effects which transform just one window.

Rendering of the EffectFrame is moved into the scene as Scene::EffectFrame with a concrete implementation in SceneXrender and SceneOpenGL.
A factory method for an EffectFrame is added to the EffectsHandler, which is used by the effects.
Next step: pass the EffectFrame through all effects, so that effects can transform, blur, invert whatever it.

Apparently a Toplevel isn't always a Client when the client rect

at the same time (in other words, only when activating compositing using the kcm).
Currently selfcheck causes bad flicker (due to X mapping the overlay window
for too long?) which looks bad during KDE startup. With this patch, KDE startup
is without any flicker.

WARNING: Breaks shadow effect. I don't think it causes anything to crash anymore but it is VERY ugly visually.
Contains:
- New decoration API that allows decorations to change the way shadows look.
- Shadows now wobble.
- API example code in the Oxygen decoration.
- Added buildQuads() effect plugin hook.
- Work on the shadow effect to use the new decoration shadow API as well.
- Added IDs to WindowQuads.
- Added public accessors to texture coords in WindowVertex.
Would like all this to be reviewed.

for use in effects (and not only). Now a list of window quads (=window areas)
is created at the beginning of the paint pass, prepaint calls can modify
the split itself (i.e. divide it into more parts). The actual paint calls
can then modify these quads (i.e. transform their geometry). This will allow
better control of how the split is done and also allow painting e.g. only
the decoration differently. Still work in progress, but it works.
Also pass data to prepaint functions in a struct, as there is
already quite a number of them.

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?

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 :-)

Effects also get access to window's vertices. This can be used to change shape of
