Thanks Mike - all of the basemap examples are now working as expected
with the transforms branch. The only significant change I had to make
was to wrap axes.get_position in a try/except block, i.e.
try:
l,b,w,h = ax.get_position()
except:
l,b,w,h = (ax.get_position()).bounds
so that they would work both with the trunk and the transforms branch.
