 // Provides configuration to mus in views. This consists of the following:
 // . Provides a Screen implementation backed by mus.
 // . Provides a Clipboard implementation backed by mus.
 // . Creates and owns a WindowTreeClient.
 // . Registers itself as the factory for creating NativeWidgets so that a
 //   NativeWidgetMus is created.
 // WindowManagerConnection is a singleton and should be created early on.
 //
 // TODO(sky): this name is now totally confusing. Come up with a better one.
