The first time this test is run, there will be no baseline image to
compare against, so the test will fail. Copy the output images (in
this case `result_images/test_category/spines_axes_positions.*`) to
the `baseline_images` tree in the source directory (in this case
`lib/matplotlib/tests/baseline_images/test_category`) and put them
under source code revision control (with `git add`). When rerunning

the correct subdirectory of `baseline_images` tree in the source
