We should have a MimeTypeHandlerRendererState object of some sort similar to
WebViewRendererState to do work on the IO thread.

This part I've inherited from Zach's old patch.
So we should just have sth like:

if (MimeHandlerViewRendererState::GetInstance()->IsGuest(info)) return true;
?

To some degree, I think. We shouldn't allow it to load ANY extension resource,
there should be a whitelist or something.

   const content::ResourceRequestInfo* info =
       content::ResourceRequestInfo::ForRequest(request);
