/**
 * Hides the system bars and makes the Activity "fullscreen". If this should be the default
 * state it should be called from [Activity.onWindowFocusChanged] if hasFocus is true.
 * It is also recommended to take care of cutout areas. The default behavior is that the app shows
 * in the cutout area in portrait mode if not in fullscreen mode. This can cause "jumping" if the
 * user swipes a system bar to show it. It is recommended to set [WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_NEVER],
 * call [showBelowCutout] from [Activity.onCreate]
 * (see [Android Developers article about cutouts](https://developer.android.com/guide/topics/display-cutout#never_render_content_in_the_display_cutout_area)).
