Of course, any solution will have to work with all backends, not just Agg. > >> This appears to be LGPL, so we will not be using it in the main distro. >> >> > > Yes, it's LGPL. > And I didn't mean to include it in mpl. > Anyhow, I think I'll go with the first method for the moment. > It sounds like this method should also be the most portable between backends. I doubt efficiency is a concern, because there's a real upper limit on the number of these annotations before things become illegible.
