Yep -- this is a bug in my view. pylab.savefig and fig.avefig respect
the setting, but canvas.print_figure did not. I updated the following
backends:
Sending matplotlib/lib/matplotlib/backend_bases.py
Sending matplotlib/lib/matplotlib/backends/backend_agg.py
Sending matplotlib/lib/matplotlib/backends/backend_fltkagg.py
Sending matplotlib/lib/matplotlib/backends/backend_gtk.py
Sending matplotlib/lib/matplotlib/backends/backend_gtkagg.py
Sending matplotlib/lib/matplotlib/backends/backend_qt4agg.py
Sending matplotlib/lib/matplotlib/backends/backend_qtagg.py
Sending matplotlib/lib/matplotlib/backends/backend_template.py
Sending matplotlib/lib/matplotlib/backends/backend_tkagg.py
Sending matplotlib/lib/matplotlib/backends/backend_wx.py
Sending matplotlib/lib/matplotlib/backends/backend_wxagg.py
Sending matplotlib/lib/matplotlib/figure.py
Those of you with svn access please give it a test drive on your
favorite backends to make sure it is behaving properly. I was able to
test several...
