24 * try puting src/sink ghostpads for each bin into invisible clusters
26 * for more compact nodes, try
27 * - changing node-shape from box into record
28 * - use labels like : element [ label="{element | <src> src | <sink> sink}"]
29 * - point to record-connectors : element1:src -> element2:sink
30 * - we use head/tail labels for pad-caps right now
31 * - this does not work well, as dot seems to not look at their size when
33 * - we could add the caps to the pad itself, then we should use one line per
34 * caps (simple caps = one line)
