There is no way to avoid information loss when saving to jpeg. But it's
true that Gwenview uses the default image quality of the Qt JPEG writer,
which is 75.

I don't think keeping the original picture quality will prevent
information loss. Saving an image several times with the same quality
will eventually lead to JPEG artefacts. Still, it makes sense to be able
to choose the default JPEG quality. I am going to add this to my TODO list.
