    Don't use extra lines for r=2 guided filter · f7d1ff49

    Changes the CONFIG_FAST_SGR=1 strategy to not use any
    subsampling for the r=1 filter, but for the r=2 filter
    sub-sample vertically but combine only by filtering
    horizontally in the last stage for odd rows.
    Coding efficiency loss sems quite minimal.
