This allows for the following options:
 Set 0:
        Inter: All 16 txfms
        Intra: Discrete Trig transforms w/0 flip (4) + Identity (1) +
               1D Hor/vert DCT (2)
 Set 1:
        Inter: Discrete Trig transforms w/ flip (9) + Identity (1) +
               1D Hor/Ver DCT (2)
        Intra: Discrete Trig transforms w/0 flip (4) + Identity (1)
 Set 2:
        Inter: Discrete Trig transforms w/ flip (9) + Identity (1)
        Intra: Discrete Trig transforms w/0 flip (4) + Identity (1)
