-// RenderWidgetHostViewWin
-//
-//  An object representing the "View" of a rendered web page. This object is
-//  responsible for displaying the content of the web page, receiving windows
-//  messages, and containing plugins HWNDs. It is the implementation of the
-//  RenderWidgetHostView that the cross-platform RenderWidgetHost object uses
-//  to display the data.
-//
-//  Comment excerpted from render_widget_host.h:
-//
-//    "The lifetime of the RenderWidgetHostHWND is tied to the render process.
-//     If the render process dies, the RenderWidgetHostHWND goes away and all
-//     references to it must become NULL."
