-// This files defines the interfaces and structures used for frames.
-//
-// When a client in the frame tree is connected to by way of the WindowManager a
-// FrameClient is obtained (from the ServiceProvider interface request passed
-// in WindowManager::OnEmbed()). The FrameClient 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 windows ids. This means that when a client creates
-// a new window to be part of the frame tree it immediately knows the id to use
-// for Frame 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()).
