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.

Due to changes in build system we have always either OpenGL or OpenGL ES.
This allows to remove the KWIN_HAVE_OPENGL_COMPOSITING define. In the
effects the define is kept as KWIN_HAVE_OPENGL which can be used in
future to build also an XRender only effect system.
Building the workspaces requires to have all the build dependencies
which were required for KWIN_HAVE_COMPOSITING to be set. This allows
us to remove all the ifdefs for this and gives us a cleaner code.
Removes the Extension::glxAvailable() from kwinglobals and
implements the functionality in CompositingPrefs, where it
is only needed. There used to be one additional check in
scene_opengl_glx.cpp which is moved into composite.cpp
before the OpenGL Scene is created.

Moved the function call of scene->windowAdded() to setupComposition() of
Toplevel. The function calls from Workspace were removed, since
windowAdded() is called by setupCompositing() now, which is called anyway.

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.

The HAVE_XCOMPOSITE_OVERLAY define had not been moved to the new
overlaywindow.cpp file causing the OverlayWindow to not be created
at all. In fact after moving the define to the new file the code
did not even compile as that code parts still used m_overlayWindow
instead of m_window.
The regression would have been easy to spot when testing with all
backends as the GLES/EGL backend still requires the overlay window.

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.
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.

In case we use OpenGL compositing and KWin is started with the raster graphicssystem,
the decoration gets painted with the raster backend.

Also add a usable "doesn't work why" info and WARN! the user about clicking the rearm button.
Merge "OpenGLIsUnsafe" and "CheckIsSafe" config keys
Move the entire checking into CompositingPrefs

With config option "NoPlugin" in group "Style" it is possible to
no request that KWin should be run without a decoration plugin.
This is a change for Plasma Active to properly support no decorations.
As well if a decoration plugin cannot be loaded, KWin will no longer
exit, but continue to run just without a decoration. As a nice
side-effect changes in Oxygen no longer destroy my kwin build ;-)

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!
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.
The branch contains the first step in reworking the kwineffects
library. This includes:
* replacing virtuals by signals and slots
* dropping some unused methods
* remove KWin::TimeLine
More to come.

kwin/workspace.cpp
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.
differecens to patch atteched to 258971:
- removed debug statements
- fixed indention...
- NON vsync strategy does not rely on the estimation, but on the time passed since the last repaint trigger, allowing a precise framerate

this should improve v'syncing, maybe v'synced "smoothness"
remaining and exposed issue are "dirty textures" w/o damage events (see the requst description)
can be diminished by increasing MaxFPS above the fastest update (or shadowed below the slowest one)

This provides a significant performance improvement especially for Present Windows.
Whenever a lanczos resampling is done the resulted texture is cached, till the
window is damaged or a texture of different size is required. This means that
for a taskbar thumbnail the resampling only occurs once unless the window is damaged
and for present windows it only occurs when the windows are resized and then only
after the windows have already been moved. Highlighting windows does not cause
a resampling any more.

With Intel drivers currently the self check at KWin startup fails (no idea why) and KWin falls back to XRender. This is probably an explanation for all the complaints about slow kwin in 4.5 and the missing effects. So let's fail and make it possible to restart compositing via systemsettings and alt+shift+f12.
Nevertheless it would be nice to fix the the failing selfcheck...

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.
