oxygenexceptionlistwidget: better check index validity in "edit" method. Also update buttons status after removing items, since
apparently selectionChanged signal is not sent by Qt.

It appears that we're accidentally choosing an MSAA config with the
Intel driver in Mesa 9.0. So change the algorithm to take the values
of GLX_SAMPLES and GLX_SAMPLE_BUFFERS into account.
Found by Kenneth Graunke.
According to Pierre-Loup Griffais (Plagman on IRC) this is causing
choppy VDPAU video playback when compositing is enabled.
Removing these calls doesn't seem to cause any regressions, and the
commit that added them doesn't give a reason. So let's just get rid
of them for now.

Boxswitch is activated as tabbox, possibly due to a downstream issue
This results in multiple effects being assigned to the tabbox and no
GUI way for the user to fix this.
Since the BoxSwitch effects nowadays only exists as sidearm for
coverswitch, the tabbox setting is now hardcoded and disabled in the
effect, making it completely impossible to accidentally use it as tabbox.

Adjustment to reality. KWin has had a dependency on Mesa 8.0 for quite
some time given that it is what basically all distributions ship.
It is better to clearly state what is required. For KWin Mesa 8.0 is a
more reliable dependency as all DRI drivers which do not support DRI2
have been removed.
Packagers have been informed about this intended change some weeks ago.

During detecting the OpenGL capabilities also a recommended compositor
can be set. This recommendation is honoured by the OpenGL based
compositors. That is the SceneOpenGL2 requires a recommendation for at
least OpenGL2 and the SceneOpenGL1 requires at least a recommendation for
OpenGL1. If the driver recommends XRender compositing the SceneOpenGL
performs the existing fallback to XRender.
With this recommendation the hacks in the Scene are removed, e.g. it is
no longer checked whether the driver is software emulation as that is
provided through the recommendation.
To overrule the recommendation the environment variable KWIN_COMPOSE is
extended by the values O1 and O2 to enforce either OpenGL 1 or OpenGL 2.
This overwrites all other checks. As a side-effect this allows now to run
KWin on the llvmpipe:
LIBGL_ALWAYS_SOFTWARE=1 KWIN_COMPOSE=O2 kwin --replace &
But not that I would recommend to use it :-)

The logic has already ensured that the ARBBlurShader can only be used
when using the OpenGL1 compositor, the OpenGL 2 compositor needs to use
the GLSLBlurShader.
This change moves the complete ARBBlurShader into a KWIN_HAVE_OPENGL_1
ifdef section.
As a side-effect the ::create method can now return a NULL pointer which
makes more sense then returning an ARBBlurShader in case that the
GLSLShader is not supported.

If the build option is enabled KWIN_HAVE_OPENGL_1 is passed as a compile
flag when build against OpenGL.
This compile flag is meant to replace the KWIN_HAVE_OPENGLES. So far code
has been ifdefed for special behavior of OpenGL ES 2.0 and to remove
fixed functionality calls which are not available in OpenGL ES 2.0.
With this build flag the fixed functionality calls which are only used in
the OpenGL1 Compositor can be removed and keeping the KWIN_HAVE_OPENGLES
for the real differences between OpenGL 2.x and OpenGL ES 2.0.
E.g. a call like glColor4f should be in an
glColor4f(1.0, 1.0, 1.0, 1.0);
while a call like glPolygonMode should be in an
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
Building for OpenGL ES 2.0 of course implies that KWIN_HAVE_OPENGL_1 is
not defined.
Given that the Catalyst driver is now supporting direct rendering and by
that can use the OpenGL 2 code path we do no longer need to force
disable the Blur effect and Lanczos filters which used to crash in the
ARB shader path.
The ARB shader path - which can only be used in OpenGL 1 - is kept
disabled for Catalyst.
