Each effect is able to declare itself as currently being active,
that is transforming windows or painting or screen or doing anything
during the current rendered frame.
This change eliminates the hottest path inside KWin identified by

REVIEW: 102449
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.
There's still the possiblity of distortion if someone places the panel between two screens. But that's hardly possible to catch as it would require to animate parts of the window in one direction and the rest in another direction.

"MakeTransparent" to "Translucency" so that it matches its visible name.
