* About animation usage:

* All animation usage is implemented in this class. Animation is eye candy and

* low priority when it comes to resources -> on resource failures animation

* fails fast to release resources for more critical functionality. Also, no

*

* User inactivity is not being observed. Only one animation is used. Extension

* is CActive to make it possible to postpone animation deletion on animation

* failure.
