We'd still like cookies sent even for cross-site image requests for the 
Google Maps API, e.g. so that we can send user-personalised map tiles. For 
example, one could imagine that map tiles would be localised based on the 
user's preferences instead of based on geographic ___location or the 
embedder's language, in which case we'd need the cookie.
