.. warning::
This does not manage an GUI event loop. Consequently, the figure
may only be shown briefly or not shown at all if you or your
environment are not managing an event loop.
Proper use cases for `.Figure.show` include running this from a
GUI application or an IPython shell.
If you're running a pure python shell or executing a non-GUI
python script, you should use `matplotlib.pyplot.show` instead,
which takes care of managing the event loop for you.

unset DISPLAY), issue warning when called on a non-GUI backend.
