-// This files defines the interfaces and structures used for frames.
-//
-// When a client in the frame tree is connected to by way of the ViewManager a
-// FrameTreeClient is obtained (from the ServiceProvider interface request
-// passed in ViewManager::OnEmbed()). The FrameTreeClient is told the frame
-// tree (by way of OnConnection()), which allows the client to use other
-// frames in the tree (assuming the client has the appropriate permissions).
-//
-// frame_ids are the same as views ids. This means that when a client creates
-// a new view to be part of the frame tree it immediately knows the id to use
-// for FrameTreeServer calls.
-//
-// The server provides an id that may be used to identify the state of the
-// tree. The change id is an integer that is incremented every time the
-// structure of the tree changes. The change id is not used by the server; the
-// server only updates the change id and notifies clients of the new id (by
-// way of structure change functions such as OnFrameAdded()).
-
-// Expresses a preference for where a navigation should occur.
