This solves the regression with NVIDIA drivers resulting in a black screen.
Apparently NVIDIA does not support glXCopySubBuffer and the copying of pixels
fails with a shader bound.
So unbinding the shader before copying the pixels and rebinding the shader
afterwards resolves the issue.
This allows to remove the temporary hack to make NVIDIA work, again.
possibly prevents leaking ItemInfos
secure some accesses (selected_window), not sure whether this caused the unreproducable crash when used as proxy in coverswitch

KWin's new shaders fail with NVIDIA and present just a black screen
for the ortho shader (generic shader seems to work). Temporarily
disabling the shaders to force a fallback to old rendering code.
Of course the bug in the shader needs to be fixed.
Apparently glXQueryDrawable does not work in NVIDIA blob for binding
a texture from an icon. This fixes an abort, but the root cause should
be found and fixed properly.

Oxygen::ShadowCache::shadowSize() now returns the shadow extend outside of the window body (the extend)
Overlab between the actual shadow pixmap and the window body is dealt with internally (by creating larger pixmaps)
This allows notably Oxygen::Client to not attempt to draw shadow when shadowSize == 0 (which was never the case
before)
The flag has been made obsolete by the fact that window corners are not part of the shadow anymore.
Configuration::useOxygenShadows is now dealt with by setting the active flag directly.
invert.cpp refers to the apparently removed kwinshadereffect.h,
so it's probably missing out on some sort of porting activity.
