// A RenderViewHost is responsible for creating and talking to a
// `blink::WebView` object in a child process. It exposes a high level API to
// users, for things like loading pages, adjusting the display and other browser
// functionality, which it translates into IPC messages sent over the IPC
// channel with the `blink::WebView`. It responds to all IPC messages sent by
// that `blink::WebView` and cracks them, calling a delegate object back with
// higher level types where possible.
//
// The intent of this interface is to provide a view-agnostic communication
// conduit with a renderer. This is so we can build HTML views not only as
// WebContents (see WebContents for an example) but also as views, etc.
//
// DEPRECATED: RenderViewHost is being removed as part of the SiteIsolation
// project. New code should not be added here, but to RenderWidgetHost (if it's
// about drawing or events), RenderFrameHost (if it's frame specific), or
// Page (if it's page specific).
//
// For context, please see https://crbug.com/467770 and
// https://www.chromium.org/developers/design-documents/site-isolation.
