Yes, nautilus only ever uses the 128x128 thumbnails. For actual images
we use the file itself as the thumbnail whenever an icon is scaled
larger than 128 pixels (since nautilus 2.22). This does not work for
things that require a thumbnailer.

We could add support for 256x256 thumbnails, but I don't know how useful
this would be, icons of that size are rather unusual.
