- * SECTION:restart
- * @short_description: Smoothly restart the compositor
- *
- * There are some cases where we need to restart Mutter in order
- * to deal with changes in state - the particular case inspiring
- * this is enabling or disabling stereo output. To make this
- * fairly smooth for the user, we need to do two things:
- *
- *  - Display a message to the user and make sure that it is
- *    actually painted before we exit.
- *  - Use a helper program so that the Composite Overlay Window
- *    isn't unmapped and mapped.
- *
- * This handles both of these.
