Remove support for OpenGL compositing without using a composite
overlay window. With this change kwin now also requires a
double-buffered framebuffer configuration.
glXCreateNewContext() is supposed to return NULL on failure, so let's
assume that it does. Don't try to create an indirect context when
creating a direct context failed. glXCreateNewContext() should return
an indirect context when a direct context cannot be created.
Use glXChooseFBConfig() instead of glXGetFBConfigs(), and prefer
the first usable configuration instead of the last.
Also rename initBufferConfigs() to initFbConfig().
Noticed this one during test compile against Qt5 as QX11Info is no longer
exposing appVisual. Using the visual from root window which works just
fine for this use case.

Tried to build KWin with enable final: it doesn't work. So if nobody uses
it, we don't need it in the CMakeLists to make it work.
Also it's removed in KF5 which means that removing it right now removes
differences in the build system.

Adding a new property on whether we want animations based on whether we
are on raster or with Compositing. The property is constant as the deco
gets recreated on compositing change state anyway.

BUG: 314532
FIXED-IN: 4.10.2
If a KWin script uses a ThumbnailItem which gets created before the
Compositor is fully initialized the thumbnail is not shown at all because
the connect to windowAdded etc. will never happen.
Therefore connect to Compositor::compositingToggled to re-connect
whenever the compositing state changes.

Since color correction got pushed merged in the Lanczos Filter is only
created for OpenGL2. Which means the complete ARB shader code path has
been dead since 4.10 anyway.

The scratch PaintDevice is provided by the PaintRedirector's subclasses
allowing the ones wanting a QImage to provide the QImage directly and the
ones needing a QPixmap to provide a pixmap. This means the copy from
QPixmap to QImage is no longer needed in the OpenGL and XRender/raster
paint redirector.

Ownership of decoration textures is moved from SceneOpenGL::Window to
OpenGLPaintRedirector. The PaintRedirector is responsible for updating
the textures whenever they change. For this GLTexture is extended by an
update(QImage, QPoint) method which uses glTexSubImage2D to update only
the changed parts.
The big advantage compared to before is that if e.g. only a button is
animated only the button part is updated instead of the complete deco
part.
PaintRedirector is turned into an abstract class providing a factory
method which returns either an instance of
* OpenGLPaintRedirector
* NativeXRenderPaintRedirector
* RasterXRenderPaintRedirector
OpenGLPaintRedirector is basically doing exactly the same as the parent
class used to do before. Though the idea is to extend the functionality
to have the PaintRedirector write directly into OpenGL textures to limit
copying the complete decorations.
NativeXRenderPaintRedirector is similar to OpenGLPaintRedirector by
rendering into a QPixmap and providing the pictureHandle for the QPixmap
to SceneXRender.
RasterXRenderPaintRedirector is providing the functionality for the case
that the QPixmap/XPixmap relationship is not present. From the QPixmap
containing the pending decoration paint a QImage is created and then the
relevent parts are copied directly into the decoration pixmap.

Many headers included KLocale to use i18n and co. But those methods are
defined in KLocalizedString and not in KLocale.
With KF5 klocale.h does no longer include KLocalizedString causing lots
of compile errors.
