Yes, this would be great. Is there progression since this issue was created?

I've got a situation in which there are multiple subsplines, but they result in two different edges being drawn, which I don't understand and which don't seem to fall under...

It's hard to create a small reproduction scenario. When I start to remove nodes, these strange splines also start to dissappear. If I remove all clusters, these splines don't seem...

I seem to have found a decently small enough reproduction case.  ```dot digraph "8285a152-0673-4d53-81f8-1eb06bc9b84f" { graph [ compound=true, fontsize=30, labelloc=t, margin=10, newrank=true, ranksep=3 ]; node [color=black, shape=point ]; edge...

Btw, is there a way to get this to be drawn correctly? The following code doesn't segfault, but shows no cluster boundary neither: ```dot digraph "Name" { graph [compound=true]; subgraph...

What is the exact meaning of newrank=true? I've seen it before, but it doesn't seem to be documented.

All right, so giving a segfault is appropriate then? Shouldn't dot give an error message about invalid input?

> I believe it is necessary to call gvFreeLayout. This documented in http://www.graphviz.org/doc/libguide/libguide.pdf. You are entirely correct. Is it possible to check for an existing layout right before a new...

That's a clear answer. Is the library thread-safe if different threads only access their own graph? What if the same graphviz-context object is used across the threads for laying out...

Okay, interesting. The rename confused me a bit. I couldn't find any announcement of this kind, but I'm probably not properly subscribed to the relevant mailinglists then. Out of mere...
