 // This version of RenderWidgetHostView is for builds of Chrome that run through
 // the mojo shell and use the Mandoline UI Service (Mus). Mus is responsible for
 // windowing, compositing, and input event dispatch. The purpose of
 // RenderWidgetHostViewMus is to manage the mus::Window owned by the content
 // embedder. The browser is the owner of the mus::Window, controlling properties
 // such as visibility, and bounds. Some aspects such as input, focus, and cursor
 // are managed by Mus directly. Input event routing will be plumbed directly to
 // the renderer from Mus.
