It looks like my algorithm is most closely related to Vatti, but I have improved on it in several ways.  So far I can only find references to people who are improving on the graph based algorithm and performing all-pairs brute force line intersection.  Do you know of any work that improves directly on Vatti rather than merely comparing yet-another-graph-travering algorithm to Vatti?  

Thanks,
