I there a way with the current library to fix self-intersections? I know I used a SVN version several years ago that had a dissolve routine in the extension/algorithms directory that seemed to do the trick, but the extensions directory doesn't seem to exist anymore. I tried to grep through the sources, look at all the examples, and read through the documentation again, but can't seem to find the same functionality. I suspect I just don't know what it is called, so any suggestions on how to go about repairing the results of a sequence of polygon boolean operations to remove these self-intersections would be great.
