    Search and pick filter level for each superblock after the entire
    frame has been encoded. And then apply loop filtering using
    selected filter levels.
    Now it can't work with LOOPFILTER_LEVEL. Y, U, V planes share the
    same filter level.
    Per superblock, filter levels are signaled via bitstream.
    Future work: move selecting filter level into each superblock
    rather than wait for the whole frame encoded.
