    workspaceSwitcherPopup: Support horizontal layout
    
    While mutter supports a variety of different grid layouts (n columns/rows,
    growing vertically or horizontally from any of the four corners), we
    hardcode a fixed vertical layout of a single column.
    
    Now that mutter exposes the actual layout to us, add support for a more
    traditional horizontal layout as well.
