Adenilson Cavalcanti Da Silva 702920c810 Starting to implement pixmap based pulse animation. The first implementation
assumed that there would exist a complete copy of the animated widget to
do the pulse (where another object is kept translucent and when the animation
is triggered, it will expand and fade at same time).

But is expensive to copy the whole widget, so the idea is to draw the target
widget in a pixmap and then do the pulse effect on the pixmap itself.

It is still broken, for some reason the opacity is failing to animate (should
fix this tomorrow).
