 * Do not include graphviz/types.h here since it conflicts with ncurses

 * The previous workaround of inserting the graph_t definition here does not
 * work with graphviz >= 2.30.0 since it depends on the define WITH_CGRAPH.
 *
 * For that reason a lot of functions simply take a void* instead of graph_t*.
