Mauro: That's a bug - the fillcontinents method was only returning the
last Polygon instance drawn. I've fixed it in SVN (r6579) to return a
list of all the Polygon instances. You can now iterate over that list
and remove each Polygon, like this
contpolys = m.fillcontinents()
for contpoly in contpolys:
contpoly.remove()
Thanks for the bug report.
