On a related issue: when exporting a figure from the tkagg backend
(using the appropriate button) to PNG, the dpi is arbitrirarily set to
300 (see backend_tkagg.py in NavigationToolbar2TkAgg.save_figure):
self.canvas.print_figure(fname, dpi=300)
I think it should honor the savefig.dpi rc setting:
self.canvas.print_figure(fname, dpi=rcParams['savefig.dpi'])
so that using savefig('toto.png') in the script or exporting it from the
window is equivalent. I dont't know if this happens w/ other 'GUI' backends.
Cheers.
