Due to changes in the blur effect, the EffectFrame was flickering
with GLES. This can be worked around by doing full repaints whenever
a window is damagded while boxswitch is active with GLES. The problem
only occurs with the GLES backend due to the way how the buffers are
swapped.

Well we don't have another choice if half of the drivers crash kwin
whenever you watch a fullscreen flash video or use a screen saver.
Unredirect Fullscreen Window was quite useful in case you used
to play heavy OpenGL games, but pretty useless for anything else.
For the game and hd video usecase we nowadays have the better way
of really suspending compositing (either by the client indicating or
with a window specific rule). The plus of suspending compositing is
that the driver doesn't crash.
And yes we are "supposed" to no longer workaround driver bugs.
Good joke, I like to redirect my inbox to everyone who things we
are not allowed to workaround driver bugs.
CCBUG: 252817
The deep copy does not work with raster as it creates a non-native
pixmap. In fact the deep copy is not needed any more as it was a
safety check during development when apps using raster could crash
kwin.
With raster a QPixmap is no longer a XPixmap which fails all code
which assumes that an QPixmap is an XPixmap. Depending on were in
the codebase we either convert such pixmaps to images (OpenGL) or
create a XPixmap and use QPixmap::fromX11Pixmap to get a "real"
pixmap.
It is possible that there are more code pathes were we would need
a XPixmap. Currently tested is basic functionality of no-compositing,
XRender compositing, OpenGl/GLX and OpenGL ES/EGL compositing.
For OpenGL compositing raster might result in performance improvements,
for XRender it is possible that there are regressions when using raster.
By default KWin uses whatever is the default of the system, so we just
no longer enforce native.
Of course it is a bad idea to use graphicssystem OpenGL. As that
is broken anyways in Qt, we do not check for it.
Many thanks to Philipp Knechtges for bringing up the issue, convincing
me that we need it and providing most of the patch.

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

Because:
* We have a bug in our scripts that makes extracomment not work (will try to fix this asap)
* Makes sense to be a comment since we want it to be a disambiguation text
* KUIT markers (e.g. @label) need to be in comment
The new build option restricts the building of effects to those
useable for Plasma Active:
* blur
* dialogparent
* fade
* login
* outline
* presentwindows
* slidingpopups
* taskbarthumbnails
* screenshot
Additionally all effect KCMs are excluded from building in the
assumption that when building with this option, KWIN_BUILD_KCMS
is turned off.

For now there is autostart support on all screens and support for different resolutions on different screens.
Keyboard shortcuts are still TODO

Adding a new method to retrieve whether the OpenGL implementation
uses any kind of software emulation and no software emulation can
provide GLSL support, even if it claims so.
Thanks to Maurel for testing again and again proposed patches.
BUG: 271166
Optimize the region of the screen that's painted in each frame,
and paint the windows top-to-bottom when the damaged region doesn't
intersect any blurred areas.
As KWin requires at least Mesa 7.10 for OpenGL we can be sure
that all Mesa drivers support DRI2 and can enable direct rendering
for it.
Parsing the version string to identify if it is a mesa driver.
This can cause breakage again in future versions of Mesa.
Unfortunately version, vendor and renderer are the only information
queryable just with OpenGL API.

This fixes most of the rendering issues with cube in multi
screen setups and GLSL backend. For cylinder and sphere the
rendering of areas between screen is currently disabled if
using the GLSL backend. It needs adjustments to use another
vertex shader. Not sure if it is worth the effort.
