Title: Resize transformer fix

Many changes, please look at commit comments.
I tried to commit small code changes related to one issue at time.

ResizeTransformer should now work more smoothly, because layout is redrawn only once in one pass of Drag Listener.

I removed some unnecessary methods an simplified Transformers code...
