Great work again Nick. Can't wait to see it in action. I've been
trying out the last josm-custom with map features and am finding it a
big improvement. I did find a bug though. It seems to hang when it
tries to render an incomplete area. e.g. only downloading half a lake:


download: http://www.openstreetmap.org/api/0.3/map?bbox=-2.629973842637194,51.33837122786385,-2.5918
