The renderer should be given an explicitWidth by the time its measure() method gets called. That would be a good time to choose a different size avatar and report a different measuredHeight.

It works ok (code below), but since the List itself is inside of a HDividedBox and its width can be changed, I would like to detect this event and let my itemRenderer to display bigger avatars (increase their scaleX, scaleY). How do I detect this event and where can I read-access the parent List width property?
