`paddings` you specify. `paddings` must be the same as `paddings` argument
given to the corresponding `MirrorPad` op.

The folded size of each dimension D of the output is:

`input.dim_size(D) - paddings(D, 0) - paddings(D, 1)`

For example:

```
# 't' is [[1, 2, 3], [4, 5, 6], [7, 8, 9]].
# 'paddings' is [[0, 1]], [0, 1]].
# 'mode' is SYMMETRIC.

  // it's a constant. Basically, `paddings` tensor in `SpaceToBatch` and `crops`
  // tensor  in `BatchToSpace` must satisfy the following:
  //  paddings[i, 0] = base_paddings[i, 0].
  //  0 <= paddings[i, 1] - base_paddings[i, 1] < block_shape[i]
  // (input_shape[i] + paddings[i, 0] + paddings[i, 1]) % block_shape[i] == 0.
  //  crops[i, 0] = 0.
  //  crops[i, 1] = paddings[i, 1] - base_paddings[i, 1].

    The padded size of each dimension D of the output is:

      `paddings(D, 0) + input.dim_size(D) + paddings(D, 1)`

    For example:

    ```
    # 't' is [[1, 1], [2, 2]]
    # 'paddings' is [[1, 1], [2, 2]]
    # rank of 't' is 2
    pad(t, paddings) ==> [[0, 0, 0, 0, 0, 0]
                          [0, 0, 1, 1, 0, 0]
