 // A RenderViewHost is responsible for creating and talking to a RenderView
 // 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,

 // RenderView. It responds to all IPC messages sent by that RenderView 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.
