daala_tx: New flattened 2-point Type-IV DST.
This 2-point Type-IV DST uses the same computation graph as the asymmetric 2-point Type-IV DST. Because this transform is embedded, it may be possible to remove the initial averaging step by splitting the 2-point Type-IV DST into separate forward and inverse transforms. This change also reduces two multiplication constants (forward and inverse transform) so they are less than 1. subset-1: new_dst2a@2017-12-04T01:59:12.884Z -> new_dst2@2017-12-04T01:59:57.412Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.0126 | 0.0387 | 0.0441 | 0.0554 | -0.0301 | 0.0034 | -0.0342 Change-Id: I98568e0c5b97e3a6af27653ddab845ce97d2a53d
