It would be really handy to have an option to the renderer that would link back to graphviz output from the HTML renderer of Doxygen. What I was thinking is an app-level option that takes in the path to the html output of Doxygen, and then an :image: option or some such available to classes (and the index directive too, I suppose), templated classes, etc that simply does an img link back to that location.

The app-level option the user gives would simply be the precursor part of the URL that is generated for the img tag. Make sense?

If I want to implement this, what steps should I take? I fumbled around for #44, and I never really figured out how to bolt options in to do it. Any pointers you can provide to help me bootstrap this would be appreciated. I'll take on the task once you help me get the ball rolling.
