A sliced frame drew its borders one source pixel to one sprite unit. Pixel-art sheets are small: a 16px corner on a 400-unit button is a thin line, and the only way around it was a larger image. The texture now carries `Nine-slice scale` (default 1), next to `Filter`. It sets how many sprite units one border pixel takes, for every sliced frame of that texture. The UVs stay as they are - a corner shows the same pixels, only larger or smaller. When the sprite is too small for both borders they are still scaled down together, now starting from the scaled size. With `Repeat` the tile size scales too, otherwise a doubled border would sit beside a pattern of the old size. The value is a schema row, so inspector field, saving and undo come without their own code. Anything that is not a size above 0 reads as 1, and documents without it draw as before.
