    texture-cache: Update size after setting content
    
    Since commit deec0bf2550, the texture cache is based on ClutterImage
    rather than ClutterTexture. As ClutterImage (like all ClutterContent)
    is only concerned with painting, it doesn't influence the size of the
    actor it is added to at all.
    
    That is, unlike with the previous code, the returned actor will now
    stay at size (0, 0) after the image has been loaded. We'll need to
    either update all consumers to listent to :content changes, or update
    the size when setting the content.
    
    The latter looks like the friendlier approach, and should be more in
    line what we used to do.
