Ok. Forgive me my sarcasm earlier in this thread but I really think 
automatic placement of icons at the areas is not so good.

Let me then propose different approach. Let's use the new algorithm 
to create nodes that would be rendered as icons. Such nodes should 
have a tag that attaches them to the area and the "created_by" tag 
containing the automaton name so they can be automatically moved if 
the conditions change. If for whatever reaseon the automatic 
placement is not reasonable the node can be moved by hand and have 
the created_by changed without removing its attachment to the area. 
Then the algorithm knows not to move it.

For the sake of computation complexity the area-node attachment 
should be two-way.
