animation: Scale animation actor for HiDPI

Browse Source 
The Animation class inherits from St.Bin and manages the scale factor
in the image loading, but the widget size doesn't change and doesn't
depend on the scale factor so when the scale factor is different
from 1 the widget size doesn't match the image size.

This patch resizes the Animation widget using the scale factor so the
widget will match the animation images sizes.
