test images update

So, I just tried running the test suite on matplotlib and it came back with 70+ failures. I personally don’t have the time or the focus to go through them all, but I suspect most if not all are related to some “snapping” fixes as most of the diff images seem to be related to changes in the graph borders and slight changes in text placement. Maybe it would be useful to come up with a tool that could process through the result_images directory and display the images and their diffs and help us replace the images we deem as acceptable (or bump thresholds if we don’t want to replace the image).

What do others think? Maybe someone already has such a script?

I’ve mainly done this using a thumbnailing tool like gthumb on one
side of the screen and a console to copy files on the other. Since
the diff images are already generated, it’s generally not so bad.
I’m going to try to get all tests passing before the release if
possible. Wish me luck. :slight_smile:

There are some related bug reports to this in #743 and #744.

Have a look at #779. Can you let me know if this resolves the tests
for you?
