-// InfoBar is a cross-platform base class for an infobar "view" (in the MVC
-// sense), which owns a corresponding InfoBarDelegate "model".  Typically,
-// a caller will call XYZInfoBarDelegate::Create() and pass in the
-// InfoBarManager for the relevant tab.  This will create an XYZInfoBarDelegate,
-// create a platform-specific subclass of InfoBar to own it, and then call
-// InfoBarManager::AddInfoBar() to give it ownership of the infobar.
-// During its life, the InfoBar may be shown and hidden as the owning tab is
-// switched between the foreground and background.  Eventually, InfoBarManager
-// will instruct the InfoBar to close itself.  At this point, the InfoBar will
-// optionally animate closed; once it's no longer visible, it deletes itself,
-// destroying the InfoBarDelegate in the process.
-//
-// Thus, InfoBarDelegate and InfoBar implementations can assume they share
-// lifetimes, and not NULL-check each other; but if one needs to reach back into
-// the owning InfoBarManager, it must check whether that's still possible.
