By moving the query for effects into an own thread the
startup does not have to wait till all effects are loaded.
The thread moves the loading of the effects after the
Window Manager and Compositor has been fully initialized.
This is possible as EffectsHandler is fully functional even
without any effects.
The compositor ensures that at least one frame is rendered
before the started thread returns which makes the complete
startup more responsive.

Instead of getting the information from CompositingPrefs
the running KWin instance is queried through D-Bus.
In general the running KWin should have more information
about whether Compositing will work or not.
This means the kcm no longer has to link OpenGL.

Detecting CompositingPrefs invokes an external program. Waiting
for this can be moved in a second thread.
Due to the introduction of the thread the initialization order
of KWin is changed: the WindowManager is initialized before the
Compositor. Interestingly this makes KWin felt more responsive
as the screen is not frozen for several seconds.

Toplevel::setupCompositing returns a boolean value and returns
false in the cases where it has not setup compositing.
This is used by the specialization on Client to not perform the
Client specific setup if Toplevel has not setup.

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.

Fixes a regression. When resize effect is available we can do a
fast resizing by only perform the resizing after the user ended
resizing the window.

sth. changed, possibly damage collection - dunno. however this now leads to undefined states as well
can't reproduce bug #280508 afterwards either - pot. implicitly fixing by bypassing pollution (BeFaded was
probably just resistent by different stacking order handling)
CCBUG: 280508
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.
REVIEW: 102002
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 ;-)
