On a related note, I have noticed an incompatibility between AxesGrid and
Basemap. It appears that Basemap will explicitly set adjustable='box' when
it calls ax.set_aspect(), but AxesGrid will error out, saying that it has to
be 'datalim'. What are the implications of using 'box-forced' instead of
'box' in Basemap?
