//! SLAnimManager is the central class for all animation handling.
/*!
A single instance of this class is hold by the SLScene instance and is
responsible for updating the enabled animations and to manage their life time.
If keeps a list of all skeletons and node animations and also holds a list of
all animation playback controllers.
The update of all animations is done before the rendering of all SLSceneView in
SLScene::updateIfAllViewsGotPainted by calling the SLAnimManager::update.
