Why are you trying to do your transformations while reading the file? 
Why not load the entire graph and then work on it?  Is it too big for 
that?  If you do need to look at the graph as it is being read, look at 
the parser_result object (member named "r") in the parser struct in 
<libs/graph/src/read_graphviz_new.cpp>; the parser_result type itself is 
defined in <boost/graph/detail/read_graphviz_new.hpp>.
