    Update "custom layout" spriteset import for variable frame sizes
    
    It produced a spriteset with the default spriteset frame size rather than
    the one the user specified, because that wasn't possible when it was written.
    
    NOTE: it's now possible to change box border size by importing. This is
    meant to be disallowed but it's not a serious problem so I'll ignore it for
    the moment.
