    Added a new expt rect-tx to be used in conjunction with ext-tx.
    [rect-tx is a temporary config flag and will eventually be
    merged into ext-tx once it works correctly with all other
    Added 4x8 and 8x4 tranforms for use initially with rectangular
    sub8x8 y blocks as part of this experiment.
    There is about a -0.2% BDRATE improvement on lowres, others pending.
    When var-tx is on rectangular transforms are currently not used.
    That will be enabled in a subsequent patch.
