    spin button: Limit the entry width to reasonable values
    
    When opening the value editor for any GtkAdjustment properties
    in the inspector, the popover stretches out for miles, since
    it reserves enough space to draw MAXDOUBLE. This is not useful.
    Limit the space we reserve to 8 digits.
