            textureFile = ""
            font = "vic_18"
            text = ""
            maxWidth = 170
            #c maxHeight = 18
            maxHeight = 40
            format = left
            #c vertical_alignment = bottom
                        vertical_alignment = center
            vertical_alignment = top
            fixedsize = yes
            allwaystransparent = yes
        }
