I haven't heard anything negative and got a few positive comments off-list. I haven't committed this yet because I am concerned about the implications of my changes to cm.py, colors.py and contour.py. However, if I don't hear any concerns over the next couple of days, shall I assume that it is ok to go ahead and commit? Ben Root
