 that the effect chain is the most often called code in KWin and that it is=
 not very performant due to the operator[] used all the time.

This change allows effects to declare themselve as active, which means they=
 will be included in the effect chain. If an effect is currently not active=
, it will not be called. The result is that only a very small number of eff=
ects is used in the current frame eliminating completely the hot path insid=
e kwin. After that change Toplevel::windowType and Scene::Window::performPa=
int are the most expensive methods. PerformePaint for example was not even =
in the top ten before!

PresentWindows, DesktopGrid and Slideback are not adjusted yet, because Win=
dowMotionmanager::areWindowsMoving() is not const. This will be changed as =
Slideback is now in the hot path

The analysis was motivated by complaints from afiestas about too bad framer=
ate/performance, bringing me thinking about what during rendering a frame m=
