This test does not run in CI on Ubuntu, so I'm unsure if this is a downstream environment issue or if something is broken in the package:

```
SKIPPED [1] test/test_art_resize.py:116: PIL not available
SKIPPED [1] test/test_art_resize.py:106: PIL not available
```

I'm going to skip the test downstream for now but we probably need to get CI working.
