The affine tile does allow for a small pixel area tile, to be tiled, without changing aspect ratio. Make sure x and y scale are 1, or equal, and aspect ratio will be the same. Crop the output to your desired destination size and make sure that your destination isn't changing aspect ratio. The comment about scaling down the image/needing the opposite direction to make it work, doesn't seem to make sense.
