    Use the Geolocation support in WebKitGTK+
    
    Using the infrastructure for info bars, present policy requests to the
    user so they can allow/deny them based on the URI of the frame that is
    requesting. Moving forward, it would be a good idea to offer to save
    the decision, and store it in the history entry for that site.
