Martin Gräßlin fe4329a252 Only call active effects in the effect chain
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
callgrind.
