 // This file defines the interface class OmniboxView.  Each toolkit will
 // implement the edit view differently, so that code is inherently platform
 // specific.  However, the OmniboxEditModel needs to do some communication with
 // the view.  Since the model is shared between platforms, we need to define an
 // interface that all view implementations will share.
