Actually, after generating the points, I just sort them by their Y coordinates. I am thinking it would be interesting to add a Y shift based on the height of an underlying DEM though. I'm also planning on trying to write some more interesting symbolizers that work by splitting polygons into many smaller, roughly equal size polygons; I think I could manage a way of drawing forests as contiguous entities rather than bunches of individual trees (As in Ascension's recent practice maps)
