    shaders/sampling: don't use polar compute for high radius · f56faa44

    After a certain input size, the gather kernel pulls ahead. This is
    either due to interactions with the size of the texture cache, or due to
    alignment with the 2x2 gather input grid, or both.
    Regardless, this should generally speed things up for very high radius
    polar kernels (especially when downscaling).
