// This implements the RenderViewHost interface that is exposed to
// embedders of content, and adds things only visible to content.
//
// The exact API of this object needs to be more thoroughly designed. Right
// now it mimics what WebContentsImpl exposed, which is a fairly large API and
// may contain things that are not relevant to a common subset of views. See
// also the comment in render_view_host_delegate.h about the size and scope of
// the delegate API.
//
// Right now, the concept of page navigation (both top level and frame) exists
// in the WebContentsImpl still, so if you instantiate one of these elsewhere,
// you will not be able to traverse pages back and forward. We need to determine
// if we want to bring that and other functionality down into this object so it
// can be shared by others.
//
// DEPRECATED: RenderViewHostImpl is being removed as part of the SiteIsolation
// project. New code should not be added here, but to either RenderFrameHostImpl
// (if frame specific) or PageImpl (if page specific).
//
// For context, please see https://crbug.com/467770 and
