150 libjpeg-turbo supports IDCT scaling with scaling factors of 1/8, 1/4, 3/8,

190 There is no technical reason why DCT scaling could not be supported when
192 below), only scaling factors of 1/2, 8/15, 4/7, 8/13, 2/3, 8/11, 4/5, and
206 additional DCT scaling factors.
210 This requires the DCT scaling feature, which is not supported.
213 This requires both the DCT scaling and SmartScale features, which are not
