Thanks for this! I'll try the work on my end and see what happens.

I created a quick example bgplot.py and built the doc locally. So if I change the size before adding a mesh I obtain the following:

But if I change the window size after, I got an empty frame:

I will investigate further and meanwhile I whill push the example on this branch to share our results.

Nevermind, when I cleaned the cache inside docs/ with :

$ make clean
$ rm -r examples errors.txt images/auto_generated

and re-built everything:

$ make doctest
$ make html

Then it worked for me. What about you @banesullivan ?

I think this is good to go. All good from you @GuillaumeFavelier?

Yes It's all good for me. But I pushed the bgplot.py example just for testing purpose really, should we rework it first or get rid of it before merging?

Let's get rid of that example and maybe add a better BackgroundPlotter example down the road to showcase the callback function to help users figure out how to use the BackgroundPlotter like in #387

Thanks, @GuillaumeFavelier - once the tests pass, I'll merge
