Write to stderr instead of stdout when changing Matplotlib interactivity. Otherwise the doctests will fail when debugging them. I tested this by changing it manually on my VSCode instance 😁.

I think this is okay, but what is failing with writing to stdout? |
Whatever you write to stdout appears in the doctest output, and thus it does not match the expected output anymore, failing the test. |
| enable_gui_function(gui) | ||
| if not matplotlib.is_interactive(): | ||
| sys.stdout.write("Backend %s is interactive backend. Turning interactive mode on.\n" % backend) | ||
| sys.stderr.write("Backend %s is interactive backend. Turning interactive mode on.\n" % backend) |

I'm thinking this shouldn't write to either. It should probably write to the log instead.
That would be something like this instead:
| sys.stderr.write("Backend %s is interactive backend. Turning interactive mode on.\n" % backend) | |
| pydev_log.debug("Backend %s is interactive backend. Turning interactive mode on.\n" % backend) |

Of course after importing pdev_log. Maybe that causes some import problems though and it's why this code was writing to stdout.

I changed it to stderr because I saw it writing to stderr in other places in the same file, but logging is fine to me, as long as it does not end in stdout.

Yeah not sure why it's writing to stderr instead of log elsewhere. I believe this code was originally a port from somewhere else and maybe whomever ported it didn't bother to make it write to the log instead.
