plasma-framework/animations/fade.cpp
Adenilson Cavalcanti Da Silva 818e93a576 Amazon sized patch... So many changes that I can hardly remember what they are,
but this is the list from what I can recall:
- removing expand animation (it is a case of grow animation)
- removing AbstractAnimation and using QAbstractAnimation as the common base
- animations are non longer factories, but real animation (so it is just no
issue to mesh then with user created animations)
- animation group will correctly revert the direction of all subanimations
(useful for rewinding an animation)
- fixed opacity effect in pulse animation (now it works correctly)
- there is not 'forward' property, but animation 'direction' (this is how
rewinding an animation must be done)
- direction now is movementDirection property (used in SlideAnimation and RotationStacked)
- the weakpointer for the actual animaiton is non longer in AnimationPrivate but
in each specialized animation class
- hide property is being removed (in progress) since it really is a case of Fade

I guess this is it, now is just a matter of iron out the remaining bugs and polish
the public API.
