[Daniel Holbert [:dholbert]]

This probably more-directly belongs in ImageLib, given that per https://github.com/w3c/PNG-spec/issues/310#issuecomment-1883520532 it seems the issue is just the fact that we ignore (don't parse?) EXIF information from PNG images.

If we had that information parsed/available in imagelib, presumably we would honor it in layout, just like we do for JPEG images.
