This patch adds a new function Toplevel::addLayerRepaint, that in contrast
to addWorkspaceRepaint does not invalidate every blur texture cache that
overlaps with that region. As the name suggests it rather invalidates the
to the window associated layer at that position. This is especially useful
in the case of move/resize events in combination with oxygen-transparent,
where the altered window is almost always the topmost window and the blur
texture cache of the windows underneath are unchanged.
For the case of fully opaque windows the behaviour of addLayerRepaint
and addWorkspaceRepaint should be same.

Property invokes virtual methods returning false by default. Deleted
reimplements the isDeleted and returns true. Client returns true for
isClient. Method is not called isManaged as this is already used
inside Client.
If possible use the property to Toplevel or Client instead of the
pure virtual methods. This makes it easier to get a stable ABI.
Adding new methods to the class no longer requires to add a pure
virtual method.
From a performance point of view this change should not matter.
Most EffectWindow methods are not invoked during the repaint chain.
But only in response to an event like a window got added. There the
overhead does not really matter as well the previous implementation
made strong use of dynamic casts which are also not knwon for being
very fast.
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.

Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by
callgrind.

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.

The uniforms textureWidth and textureHeight were only needed for
normal windows. For everything else it was just 1.0/1.0, that is
normalized.
The makeArrays method is changed to produce normalized texcoords
obsoleting the need for these uniforms. So two uniforms less, one
calculation in vertex shaders less and many many lines of code
removed.
At the same time makeArrays is also adjusted to take care of
yInverted of the texture, which is needed as we no longer can use
the enableUnnormalizedTexCoords which did the yInverted transformation.

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 used by any effect, so we save one complete go through
all effects pass on each window damage.
The functionality which could be provided by this hook can also be
implemented using the window damaged signal.
The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
