// CefRenderWidgetHostViewOSR
//
// An object representing the "View" of a rendered web page. This object is
// responsible for sending paint events to the the CefRenderHandler
// when window rendering is disabled. 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."
//
// RenderWidgetHostView class hierarchy described in render_widget_host_view.h.
