    vp9: Add phase to get averaging filter for 1:2 downsampling. · 348bdc01

    The scaling filter with zero shift will give sub-sampling for
    2x downsampling. Allow for a phase shift to get an averaging filter.
    Usage is for source scaling in 1 pass SVC mode for 1:2 downscale.
    Reduces aliasing in downsampled image.
    Keep the phase to 0/off for now.
