    background: Make icon list smaller on netbooks
    
    The default treeview is quite tall by default, and with the addition
    of the shell's toolbar, the titlebar and the GNOME shell panel,
    the background panel would be too tall for netbook computers.
    
    This works around the issue by setting a smaller height request
    for the icon list when the screen on which the panel will be shown
    are no taller than 768 pixels.
