Add test for issue #1484

[openandclose]

Thank you for fixing #1484, and adding API for TrimBox etc.

How about adding test for box coordinates (since I had to check and already had written)?

Yes, a good idea. Thank you.

Oh I remembered GPL conplicaitons.
Don't use my code. I'm fine.

Personally, I thought this was precisely the subject to add tests preferentially,
and this was a good occasion to do so
(even without my kind-of pull request, that is, with your code).

Do you have a different plan?
Then I'll have to close this discussion.

You can close it: the next version 1.19.5 will have this type of test.
