    EXAMPLE
        -- delete the layers associated this layer_info structure --
        DeleteLayer(li,simple_layer);
        DeleteLayer(li,smart_layer);
        -- see documentation on deletelayer about deleting superbitmap layers --
        my_super_bitmap_ptr = super_layer->SuperBitMap;
        DeleteLayer(li,super_layer);
        -- now dispose of the layer_info structure itself --
