    Perform fade-in animation on ChamplainTile and not the containing actor
    
    Under GTK 3 if we perform the animation on the content actor,
    the animation doesn't work properly. For now it remains mystery
    why this happens. At the moment we are fine with this solution
    but if we implement some better zoom-in/out animation that
    fades-in the loaded tile into the scaled tile from the previous
    zoom level, we may need to animate the new content actor on top
    of the old content actor inside the tile.
