          // specified. Since we're not using multiple skins, we do not have to worry about them in LML templates at all.
          skinService.addSkin("default", VisUI.getSkin());
          // Since we use FitViewports, we need to set a stage resizer that does not center the camera:

docs: This action will be invoked when the application is being initialized. Actions are sorted by their priority and
  invoked in descending order; by manipulating the priority values, you can fully control the flow of your
  application's initiation.
  
  @param skinService its instance will be injected into the method. We're using this service to register VisUI
  skin. Again: VisUI is an extension, so we have to register its skin manually. Fortunately, it doesn't
  require much work.
