I think if you declare ContentSettingBubbleBridge as a friend, you'll be able to
call SetAnchorRect directly which is a bit neater (and it's a common pattern for
a Bridge class to be a friend/inner-class of one of the things it's bridging).

But! of course... you can't do this if we go for a standalone function in
browser_dialogs.h, so I'll update the comment there. I think a friend is the
least intrusive approach, but c/b/ui/views owners may have a different opinion
(e.g. for some of the other dialogs, we overloaded the constructor)

I guess we could also declare a friend *function*, but that's not a common
practice in Chrome -- friend classes are easier to understand and nicer to
maintain.
