||This interface can be used for objects to be automatically beeing animated
by the render loop.
||An Animator takes Animatable Nodes and animates them by a constant loop.
||This interface is used by the ExtRenderLoop to notify other objects that
an Interval was hit.
||An OperationScheduler is capable of handling ScheduledOperations, which are
to be executed by the render thread.
||Thsi interface allows for scheduled picking.
||If you want an operation to be done by the rendering loop (for thread safety),
pass an object implementing this interface to the scheduleOperation
method of the RenderLoop.
