Since the EffectFrames have been moved into KWin core nothing in the
Effects lib actually used Plasma. The only remaining method is moved
to core as it's not used in the Effects. The Effects itself still
link against Plasma, so nothing changes for them.
The Plasma includes in the kwineffects header seemed to pull in
quite some additional headers, so the includes in some effects have
to be adjusted (most often KConfigGroup). This should speed up the
compilation of the library and the effects.
possibly prevents leaking ItemInfos
secure some accesses (selected_window), not sure whether this caused the unreproducable crash when used as proxy in coverswitch

CCBUG: 253079
invert.cpp refers to the apparently removed kwinshadereffect.h,
so it's probably missing out on some sort of porting activity.

The shadow effect is known to be broken since at least 4.5.
It is unfortunately in a state which makes it difficult to maintain
and the architecture has some serious drawbacks. Therefore it is the
best solution to replace the effect with a new and better
implementation. For more information about the new implementation
please see the discussion on KWin mailinglist:
http://lists.kde.org/?l=kwin&m=129607406517609&w=2
This also "fixes" all existing bug reports about the shadow effect.
Most of the bugs will really be fixed when the new shadow system is
implemented, if not it is a new bug and a new report should be created
for it.
Please excuse that we go this unnormal approach to mark bugs as
fixed with code removal.

The usefulness of the snow effect is doubtable and it is rather
difficult to port the effect to the new rendering architecture
introduced with GLES. It is probably easier to rewrite the complete
effect from scratch, therefore it is removed for now.
I might consider readding it for 4.7.
This kind of "fixes" snow related bug reports.

The effect has been known to cause some problems for quite some time
and is not really useful. Therfore dropping the effect.

It now uses a GLShader for GLSL shaders and pushes it using the
ShaderManager.
It does not work with the nouveau driver plus GLES, but it works
with fglrx + desktop GL 2.x, so I assume it is a driver problem here.
It uses a generic vertex shader and because of that it needs to
mark all windows which are inverted as transformed.
There is currently a conflict with Lanczos (or thumbnails) and with
the desktop in cube effect.
Rotation is now only handled by the QMatrix4x4 m_rotationMatrix,
so no more need for display lists. Resulting in a cleaner code without
differences between OpenGL 1.x and 2.x/GLES.
