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.

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 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.

The KWin::TimeLine class was only a small wrapper around QTimeLine
without adding anything to QTimeLine what is not present in QTimeLine.
The initial idea was to make it possible to provide more curve shapes.
This is now obsoleted by Qt shipping more useful curves with QTimeLine.
So let's clean up a little bit and use QTimeLine directly instead of
the small wrapper.
All effects are adjusted to use QTimeLine directly.
First a signal is emitted when the user starts a move/resize operation.
During the move/resize operation each geometry change emits an update signal.
Last but not least a finish signal is emitted.
This eliminates the specific method for geometry updates in drawbound resize
mode.
EffectsHandlerImpl connects to the Workspace signal clientActivated.
The emitting of the signal is slightly moved from before the activation logic
to after the activation logic. This might change behavior in the scripting
component, but the previous code looked wrong.
its own directory, cleaned up the effect config macros and renamed
"MakeTransparent" to "Translucency" so that it matches its visible name.
