    8x8 transform support in splitmv. · 84ea002e
    Ronald S. Bultje authored
    For splitmv, where partitioning is 8x16, 16x8 or 8x8, this patch
    uses the 8x8 transform (instead of the 4x4) if txfm_mode is
    ALLOW_8X8 or ALLOW_16X16. For TX_MODE_SELECT, splitmv can indicate
    which of the 2 transform sizes (4x4 or 8x8) it wants to use.
    
    Gains (with hybridtx4x4/8x8/16x16 and tx_select experiments
    enabled) on derf: +0.9%, HD: +0.4%, STD/HD: +0.8% (SSIM or overall
    PSNR, both metrics show similar improvements).
