Added a small check in Client::checkWorkspacePosition which will assure
us that no window ("client") is left in a offscreen position. this is
more a workaround than a proper fix but is the only thing we can do that
will be backportable to the 4.7 branch.
KWin gets compiled twice if OpenGL ES is available
and a second binary is created. It is linked against
the GLES effects and kwinglesutils and does not link
against OpenGL. The normal OpenGL variant is still
the "kwin" binary.
This is an intermediate step till we have the scene
as a loadable plugin. Then we will determine whether
OpenGL ES is supported in an external application
and load it as a plugin, otherwise we load the
OpenGL/GLX scene as a plugin.

All OpenGL related files are build as a kwinglutils library for OpenGL
and as a kwinglesutils library for OpenGL ES. The appropriate defines
are set using target_properties and removed from kwinconfig.h.cmake.
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.

When a screen is disconnected XRandR emits 3 events instead of just one:
1-Disconnected screen resized
2-Disconnected screen moved
3-Disconnected screen removed
Before this commit we were calling desktopResize on each event which
between other things restart the composite (not necessarily the faster
thing to do...).
So, in order to be able to call desktopResize only once, now we're
handling individually each event, when one of them happens a QTimer is
started/restarted on each event and desktopResized is called owhen
QTimer.timeout
The current interval is 100msec
I still don't understand how I actually tested my patch
before committing. It was working, sigh. That were
several hours of annoyance including a git bisect presenting
my own commit I assumed to be correct. Sigh.
If the environment variable KWIN_GL_DEBUG is set to 1
the define KWIN_SHADER_DEBUG is added to the glsl
source code allowing to add some custom ifdefed
visual debug handling.
As an example it's added to scene-fragment.glsl to
paint everything in a greenish way.
To get rid of direct method calls and numerous #ifdefs a new signal
configChanged() is introduced to class Workspace. Every module
which is interested in reloading the configuration is needed to connect to
this signal.
Initially this is done for the reconfiguration of DesktopChangeOSD().
Since there still is a signal available in class Workspace which is
emitted if the number of desktops has changed, we now make use of it
by transforming numberDesktopsChanged() into a Q_SLOT. It is connected
to the appropriate signal and all direct method calls from Workspace were
removed.
