    vp9: SVC feature to use partition from lower resolution. · fdb054a0
    Jerome Jiang authored
    For SVC with 3 spatial layers:
    Add feature to copy/upscale partition from middle spatial layer
    to the upper/highest resolution, when superblock sad is not high.
    Enabled for speed >= 7 and only for non-reference frames.
    Speedup ~3-4%, small loss in avgPNSR/SSIM of ~1%.
