Hi Phil, I think it's a "feature". It's a question of which of rev and putting coord1 backwards you consider to be reversing the direction around the wheel and which you consider to be flipping the colourscheme. You could argue that it would make more sense to have it the other way round. Either way, I would suggest the best way forward is to ensure that the documentation is clearer and consistent with what is actually done rather than making a backwards incompatible change to code that has been around for a long time.
Patches gratefully received!
