If you want to change the resolution, most of the time you need to do
that on the remote side. A few VNC servers have support for client side
resizes (ExtendedDesktopSize), I don't know what server you're using.
For scaling you can enable that in vnc.html's side bar settings, and in
vnc_auto.html you should be able to add `?scale=true` to the URL (or
`&scale=true` if you have other query parameters already).
PS, you should poke OpenStack to upgrade noVNC. vnc_auto.html is very
old, that file hasn't been around for 5 years.
