Thanks for your suggestion and the patch.
However, I'm not very inclined to make such a change any time soon,
since that custom axes class is one of my primary motivation
(supporting the cuvelinear grid) behind the axes_grid toolkit. And
other part of axes_grid toolkit depends on this behavior.
On the other hand, I'm trying to make some reorganization effort of
the axes_grid toolkit in the future, during which I will try to
separate out things that depends on the custom axes.
FYI, note that you can turn off the customized behavior by
ax.toggle_axisline(False)
http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#axisline
This should bring back the original behavior of the matplotlib axes
(if it does not, it should be considered a bug). Of course this will
disable some of the functionality of the axes_grid.
I'm thinking about issuing a warning (about the different behavior
from the original matplotlib) whenever axes_grid is imported
(optinally turned off using rcparams). This may help others not to
wast their time when something does not work.
