Look at the code, it centers the text now :-)

(not perfect, but working-- feel free to refactor, naturally)

NodeView.java has an old method from CellView for that, commented out. 
But I haven't really been thinking anything, rather following the XP 
method: write a test, do *something*, read code, see whether you find a 
better way (refactoring).

So far we use a fixed scale, set by the node view. If you want to change 
the views so that they determine the scale, you need to change the 
NodeView interface so that the view can give the scale (but you know that).

Ok.

Yes.

I don't think so. I want to change the properties of the 
negward-connected nodes to be right-aligned, but otherwise I think they 
are ok now. Except if someone has an idea for improvement, of course :)
