- * Hide puts that portion of screenr now on the screen into the window's save area.
- * Expose puts that portion of screenr now in the save area onto the screen.
- *
- * Hide and Expose both require that the layer structures in the screen
- * match the geometry they are being asked to update, that is, they update the
- * save area (hide) or screen (expose) based on what those structures tell them.
- * This means they must be called at the correct time during window shuffles.
