Re: stats

As I can imagine some examples that demonstrate dynamic graph drawing with ming or gd, I think it'd be cool to have. However, I looked at dcdflib.c and only found it was coded not in C but in pseudo Fortran. That's worth a glance :) So the last concern is its stability, since it simply uses static variables in the application-level context (not in a thread-local context). This is fixable though.
