/**

* This class needs to be in .cpp file so that we do not accidentally make it

* derivable; that would destroy all the binary compability advantages this

* class has..

*

* 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

* attempt to (re)construct failed animation is made.

*

* 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.
