* edge [ constraint=false ];
* this creates strange graphs ("minlen=0" is better)
* try puting src/sink ghostpads for each bin into invisible clusters
+ *
+ * for more compact nodes, try
+ * - changing node-shape from box into record
+ * - use labels like : element [ label="{element | <src> src | <sink> sink}"]
+ * - point to record-connectors : element1:src -> element2:sink
+ * - we use head/tail labels for pad-caps right now
+ * - this does not work well, as dot seems to not look at their size when
+ * doing the layout
+ * - we could add the caps to the pad itself, then we should use one line per
+ * caps (simple caps = one line)
