Re: [matplotlib-devel] SpanSelector with gtk3cairo backend

[Jens N. <jen...@gm...>]

There was an issue with the GTK3Agg backend on Python 3 due to a missing
feature in the python 3 port of PyCairo but this has been fixed in
Matplotlib 1.4.0 by making it possible to use cairocffi as an alternative to
PyCairo. CairoCFFI implements the missing feature. (While the Agg backends
doesn't use Cairo to render the figures it still needs python binding for
Cairo AFAIK)
