    workspacesView/workspacesDisplay: Scroll on horizontal layouts
    
    WokspacesDisplay simply remaps the scroll direction into the next
    workspace, but that doesn't account for the new horizontal layout.
    
    Scroll horizontally on horizontal layouts when scroll direction is
    on the vertical axis.
