Left over from the cleanup which basically resulted in the active window
being put to the inactive's window opacity.
Thanks for the early notification of that issue.

The effect should have had two animations:
* on move resize
* on active/inactive change
But the timeline was adjusted in the prePaintWindow call and the timeline
is effect global and not per window. Which means that for each window the
same time is added. So instead of adding time t each frame t*n with n
being the number of windows got added. So in most cases the animation
ended in the first or second frame which means its not visible.
Through git blame I was able to track down that this incorrect behavior
was introduced in 2008. An animation broken for more than four years
without anybody noticing is probably not required. Because of that it's
dropped from the effect. As this includes quite some code and performance
improvements it goes into the release branch.
A better solution could be implemented, but that should be for 4.10.

There were quite some useless checks like e.g. first checking whether
a window is the desktop and taking a different code path for that case
and in the other code path checking again.
Also using the new introduced boolean values for the checks instead of
comparing floating point numbers all the time.
The effect gets a set of boolean values to check whether it is active for
one of the categories (e.g. move resize, decorations).
This allows to easily check whether the effect is active at all, that is
if all values are at 1.0 the effect will never affect a window.
In all other cases it can be combined with looking at the available
windows to e.g. enable the effect for move resize only when there is a
window which is either moved or resized. This check is performed whenever
an action happens which could cause a window to become inactive.

The Shader might have left-overs from last usage which might

The supportInformation is extended to also read the properties
on all effects. In addition each effect can be queried just for
itself through D-Bus, e.g.:
qdbus org.kde.kwin /KWin supportInformationForEffect kwin4_effect_blur
All effects are extended to provide their configured and read
settings through properties. In some cases also important
runtime information is exposed.

Ensures that we can access the minimized property in Effects
which want to not animate a closed, minimized window.
Make use of it in the Fade Effect Script to not fade out a
minimized window which would mean showing the actual not

The logout effect was rather broken. First of all it was
excluded from build if OpenGL ES is present at build time. The
reason for this is that the effect did not work with GLES.
In order to fix that the vignetting is ported over to OpenGL 2
by using a dedicated shader. As well the lod based blur is
added through a dedicated shader and uses framebuffer blit to
get the current rendered buffer before rendering the logout
window into a texture.
Last but not least the isActive method was broken and is fixed
by checking whether the logout window is around.

Cube effect modifies the ScreenTransformation matrix. While each
window resets the matrix on a global level it's not reset. That
means if the last rendered window had the screen rotated the
ScreenTransformation keeps the rotation even after the cube
ended. This causes a rotated window in e.g. TaskbarThumbnails.

Effects can specify their minimum requirements in their
desktop file:
* OpenGL
* OpenGL 2 (GLSL required)
* Shaders (either ARB or OpenGL 2)
The configuration module uses this information in combination
with which backend KWin is currently using. So if e.g. OpenGL
is used and an effect requires OpenGL 2 a detailed error
message can be showed that OpenGL 2 is required.

A CMake variable is used to specify the name of the binary.
By default this is "kwin" but building for PA changes the
name to "kwinactive". The variable adjusts all names, e.g.
kwinnvidiahack becomes kwinactivenvidiahack.
The remaining usage of kwinrc in core and libs is replaced
by a cmakedefine for the configuration name and all data
installations are moved to the defined name. Dynamic loading
for scripts & co is adjusted for loading based on defined name.
This change allows the side-by-side installation of both kwin
for desktop and kwin for Plasma Desktop without the known
issues like conflicts in config files or missing build options
if kwin desktop is used for Plasma Active.
Likewise the KCMs are not adjusted as they are not intended to
be used for kwinactive.

Creating an EffectFrame requires I/O which takes on my system
during testing between 10 and 40 msec. Also it needs a little
bit of memory.
This changes moves out the creation of EffectFrames at Effect
load till the Effect actually needs the EffectFrame. E.g. if a
user does not filter in PresentWindows there is no need to ever
create it.
BoxSwitch effect is ignored as it should be dropped for 4.9.

Cube effect loads 0 to 2 textures which has been
performed during configuration. This change delays
loading the textures till cube is activated for the
first time and the loading from file is moved into
a thread.
This means that for a very short time the texture
is not yet visible, but this is not a problem as
the cube animates from fully opaque starting state.
So during the loading the texture would not be
visible anyway.
