It used to get the individual screen geometries from QDesktopWidget.
We don't need to go through QDesktopWidget any more as Screens
contains all the information we need in a more reliable way.
A new implementation of the Screens interface is added which uses XRandR
directly instead of relying on QDesktopWidget. The implementation is
provided in a new implementation file screens_xrandr.cpp.
XRandRScreens comes with a unit test. Unfortunately it's rather difficult
to provide a proper unit test against XRandR. Xvfb (which is obviously
used on the CI system) doesn't provide the XRandR extension. Also on a
"normal" developer system one would not want to just execute the test as
the results are not predictable (number of available outputs?) and the
test would mess up the setup resulting in nobody wanting to execute the
test.
As a solution to both problems the unit test starts Xephyr as a nested
X server. This allows to have at least some limited tests against XRandR.
Nevertheless there are a few things which I was not able to test:
* multiple outputs
* no output at all
The nested X Server approach makes the interaction rather complex. Qt
opens it's connection against the main X Server thus QX11Info provides
a wrong connection and also KWin::connection() which is heavily used by
xcbutils and thus all the RandR wrappers have the wrong connection. To
circumvent this problem the test is GUILESS. In case it would call into
any code using QX11Info, it would probably either runtime fail or crash.

Only needed for ScopedCPointer which can be defined in both utils and
xcbutils.h.
Not having utils.h in xcbutils.h makes it easier to have unit tests use
xcbutils.h as it removes the dependencies.
This is the only place where it is called.
There was also no need for this function to be virtual since it's not
reimplemented anywhere.
This also fixes the GLTexturePrivate being created only to be
immediately deleted and replaced by a new GLTexturePrivate when the
GLTexture(QImage) constructor was used.
With this change the structure of the GLTexture effectively becomes
immutable to the outside world; the contents of the texture images can
change, but the texture images themselves cannot be reallocated.
QImage::Format_RGBA8888_Premultiplied is the equivalent of
GL_RGBA/GL_UNSIGNED_BYTE, so use QImage::convertToFormat()
instead.
This commit also makes the texture upload code work correctly
on big-endian systems.
Register a callback function for debug output when KHR_debug or
ARB_debug_output is supported.
Only error messages and warnings about undefined behavior are
enabled in release builds, while all debug messages are enabled
in debug builds.
In case the inheriting class of X11EventFilter is a child of
Workspace and deleted by the QObject dtor of Workspace the
Workspace::self() pointer is no longer valid and already set to
nullptr.
The build option got introduced for Plasma Active back in a time
when we did not properly aim for convergence. In a Plasma 5 world
we want to have only one shell and one window manager which adjust
itself. This means we don't want a differently compiled kwin for
plasma active, but the same one. Thus the build option doesn't
make much sense any more. A KWin for touch interface needs to support
screenedges for the case that mouse is plugged in.

First try to locate all look-and-feel packages and check whether
they provide a WindowSwitcher. If they do they are inserted in
the list with the Package name being the user visible name.
So the good old sidebar is now called "Breeze".
REVIEW: 120914
Like with WindowSwitcher the configured value might be for the
look and feel package and thus we should first try to locate it
from the look and feel package.
We assume the configured layout name is a look and feel package. Thus
the Switcher is located at contents/windowswitcher/WindowSwitcher.qml
of that package.

Currently just opening the Desktop Effects KCM loads QtMultimedia which
in turn loads gstreamer 0.10. If one opens any other KCM in
systemsettings and changes without applying the change, the window
freezes when the warning dialog gets shown, because the warning message
pulls in Phonon with maybe the Gstreamer backend which uses
gstreamer 1.0. This is bad, bad and breaks everything.
By using a Loader the problem scope gets reduced. It still happens but
only if one actually watches a video. Only opening the KCM doesn't
trigger the problem any more.

KWIN_HAVE_EGL was set to EGL_FOUND which doesn't make sense as EGL is
marked as a runtime dependency. Instead a new build option KWIN_BUILD_EGL
is added defaulting to ON. If set to OFF neither the X11 nor the Wayland
EGL backend are built.

As we use epoxy we don't need them any more. KWin compiles, links and
runs just fine without ever trying to find OpenGL or OpenGLES.

We don't want the cursor to leave the visible area, so better check that
the cursor doesn't leave it. And when the screens changes better check
that the cursor is still on a visible screen. If not: put it back to the
center of the closest screen.
