Actually it's more a hack and should be addressed in the next
release cycle by allowing effects to modify the scene's blend
equation.

For what reason ever motion manager thinks that windows are not
moving during the start animation (but are during the stop animation).
So we also have to look on the timeline to decide whether we should
disable lanczos filter on the windows.
Now wonder the animation was stuttering.

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.
BUG: 272688
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.

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.

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.
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.
