I had the same problem a couple of days ago! Playing with the unwrap
function and the axis argument, I still did not managed to get rid of
these *** lines!

the kind of results I had are available at :
http://fsilva.perso.ec-marseille.fr/visible/tmp/
- tmp00.png : no unwrapping at all
- tmp10.png : unwrapping along the vertical axis
- tmp11.png : unwrapping along the vertical axis and then unwrapping the
first line and applying the 2pi gaps to all lines...
- tmp20.png : unwrapping along the horizontal axis
