Is there a way to change the thumbnail size for the content server, in particular when serving over OPDS?

I see that the size is being set in `src/calibre/srv/content.py`, but if I'm reading it right (and I could totally be missing something) it looks like `sz` is only ever assigned a value if you're working with docx. Otherwise, it always comes back as `None`, fails the `rest` check, and is set to the (imo horrifically) small 60x80. I know I can hand edit that and rebuild a local copy...then keep it maintained in perpetuity. Is there a way I'm missing? I hoped the "thumbnail size" for custom lists would override it, but it doesn't appear to impact display in opds at all.

Thanks!
