-| Highest quality for large images. Pixel aspect ratio is equivalent to cell aspect ratio, usually resulting in vertical stretching. Uses Unicode quadrant and three-quarter blocks (in addition to upper- and lower-half blocks, and spaces). Lossy whenever more than two colors are used within a 2x2 pixel square, lossless otherwise (bi- and tri-linear interpolation is used for more than two colors).

+| Highest quality for most large images. Pixel aspect ratio improves over NCBLITTER_2x2 but is less perfect than NCBLITTER_2x1, leading to slight vertical stretching. Uses Unicode sextants, left and right half blocks, and spaces). Lossy whenever more than two colors are used within a 3x2 pixel square, lossless otherwise (generalized linear interpolation is used for more than two colors).
