ImageMagick's `compare` can do this as well, on a pixel-level.

The issue is that in some cases, for example when the change is that a long sentence has been inserted in the middle of the document, the following headline and some of the first paragraph of the following section move to the next page. Then everything that follows is just marked red and the diff becomes useless.

Yes, thanks for the comment. I wanted to build something with golang :)
