the queue controller class is pretty heavy weight and does a lot of stuff..
in here, it seems we only need to CreateInfoBarDelegate, but nothing else from
the base class, that is, the method itself only requires the params that are
passed to it.

how about this:
class GeolocationConfirmInfoBarDelegateFactory {
  // Creates a platform-specific geolocation ConfirmInfoBarDelegate.
  static GeolocationConfirmInfoBarDelegate* create(...);
};

the in the .cc file, we just have a simple ifdef to create an instance of the
specific class... how does it sound?

reason: when there's real platform-specific behavior change, such as in the
permission context, it makes sense to to split into a base class and have
different implementations.
but in this case, it's just a matter of creating the right class, so the
overhead is probably not worth it.. wdyt?

Thanks, Marcus - yes I agree, this sounds simpler indeed.
