Yeah; and it isn't always complete, because some graphs tend to get too
unwieldy so it has to prune (you can see this because some nodes show up
with red borders).

I am not sure it is really feasible to build a complete graph for all
headers.  We have too many of them and too many dependencies.

Another useful graph to see is what files include a given header.  A
funny thing is that doxygen doesn't always display this; for example
