// 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
