This could use a test if at all possible. Not thought about how to do that but one like the one for spines should do it.

I’ve marked release critical because it’s a bug just like the one for spines.

It would be good to look at connection patches as well or any other artist that uses transforms between axes.

I’m 50/50 if we should change the default back for get_tightbbox so that most artists have set_in_layout false instead of true. That would be more backwards compatible. OTOH it is nice to catch some of these transform setting bugs which I think were occasionally an annoyance for some of these more complex artists.

I wrote a image comparison test but it fails on travis.

Do you have the testing free type installed?

No I haven't and I don't know how to install it either. The setup script say that I don't have VS 2010 installed even though I have. I don't have the knowledge or time to invest in trying to get the setup script to work on my computer.

One string seems to be just about windows7 but I don't believe that I even get that far.

I think I have the same very issue with installing/compiling the necessary libraries for the image tests. This is windows specific. One thing I haven't tried out yet (because I was always able to find workarounds for the tests) is to use precompiled windows binaries, e.g. the ones provided here.

I wrote a different test that don't use image comparision. Lets see if it works. It could probably be even easier by comparing to the default bbox but I am not sure if that is good.
