Discourse loses the top/bottom pixels when generating thumbnails

There might be some ImageMagick arguments to tweak the scaling algorithm and how it handles pixels at the edges, although any change could of course make other situations worse while improving this one.

Yeah, that’s my thought as well. It’s a scaling algorithm issue. As long as the original version is preserved, I’m not seeing a serious problem here, so I’m moving it to feature request.
