Generate the homogeneous transformation matrix of the identical 2D transformation.

hom_mat2d_identity generates the homogeneous transformation matrix HomMat2DIdentity describing the identical 2D transformation:

                     / 1 0 0 \
  HomMat2DIdentity = | 0 1 0 |
                     \ 0 0 1 /

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is not stored because it is identical for all homogeneous matrices that describe an affine transformation. Thus, HomMat2DIdentity is stored as the tuple [1,0,0,0,1,0].

hom_mat2d_identity always returns 2 (H_MSG_TRUE).

hom_mat2d_identity is reentrant and processed without parallelization.
