def set_transform(matrix):
lib.SetTransform((c_float * <NUM_LIT:16>)(*matrix))<EOL>
Replace the current graphics transform with the given 4x4 matrix.  For example, to replace
    the transform with a translation by ``(x, y)``::

        bacon.set_transform([1, 0, 0, x,
                             0, 1, 0, y,
                             0, 0, 1, 0,
                             0, 0, 0, 1])

    :param matrix: a 4x4 matrix in column major order, represented as a flat 16 element sequence.
