White artefacts around the images

While it may not be noticeable on a white background, on dark one, you get little traces around some of the images:

I'm happy to do the work to remove these, unless they're intentional?

Hi Daniel, thanks for pointing that out! No, those traces are definitely not intentional.

I'd be more than happy if you could improve the sprites to make them look cleaner on dark backgrounds. Thanks a lot for your help and for contributing to the extension!
