/* TODO:
 * 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 sizen 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)
