Antoine:  Sorry to seem dense, but I don't see anything wrong with that 
plot. I see a white border along the north and south pole, but I 
intrepret that to be missing values.  However, my eyes are notoriously 
bad.  I'd like to be to run a script that generates the artifacts 
myself, so I can zoom in and see the problem myself.  Does the 
griddata_demo.py script show the same problem for you?
