    encoder: Fix scale_and_extend_frame() for non-4:2:0 · 6d99b21b
    Timothy B. Terriberry authored
    The code to pre-scale reference frames was hardcoded to only work
    for 4:2:0. This makes it work for 4:2:2, 4:4:0, and 4:4:4, also.
    It also eliminates the special case for a fourth plane, based on the
    assert above that the total number of planes is no more than three.
