There is one quick-n-dirty way of doing it. And it ain't pretty.
Using the third-party code in a subprocess that creates a pickle of the
figure. Then load up the pickle and extract the figure object in your
parent process. Your instance of matplotlib will never be touched.
Told you it wasn't pretty...
