Ian,

I'm glad to hear that!  One possibility would be to use a temporary 
rcParam (temporary in that it might be phased out after a couple 
releases) to allow switching between the two algorithms.  This would 
make it much easier to test, and it would also allow a transition during 
which people could reproduce results obtained with earlier mpl.  It 
would also be a safety measure, in case someone hits a corner case which 
the new algorithm doesn't handle but the old one does--not that I'm 
expecting such cases to arise.
