Again, forgot something before sending:
The idea was to be able to output other kinds of graph representation.
The current one is a very clumsy attempt at ASCII-art. But we could have
added:
avfilter_graph_dump(graph, "fmt=dot");
to get output in Graphviz DOT format, basically importing
tools/graph2dot.c into libavfilter/graphdump.c. Finally doing that may
be a better idea than obsoleting the option.
And of course, other formats are possible too.
