I've implemented ccylinder/trimesh, I think it has some limitations like
maybe generating only 1 contact point (haven't looked at it in a long
while). I was going to submit a patch earlier, then a few things got in the
way, I could make a patch now but at the moment I have no way of testing
whether it still works properly, so someone else would have to do that. If
anyone's interested in giving it a try I can send them the patch.
