Replacing the 8x8 DCT with 8x8 ADST/DCT for I8x8 Fixed the code review comments. Under the htrans8x8 experiment the 8X8 DCT in the I8X8 mode is replaced with a combination of 8X8 ADST and DCT. Overall coding gains with the htrans8x8 experiment are: derf: 0.486 std-hd: 1.040 hd: 1.063 yt: 0.506 Note that part of the gain comes from bigger transforms (8x8 instead of 4x4) and part comes from replacing the DCT wth the ADST.
