-// 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

-// 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."
-//
-// RenderWidgetHostView class hierarchy described in render_widget_host_view.h.
