_D_e_s_c_r_i_p_t_i_o_n:

     Sets 'matrix' to be the affine transformation given by 'xx', 'yx',
     'xy', 'yy', 'x0', 'y0'. The transformation is given by:

     x_new = xx * x + xy * y + x0;
      y_new = yx * x + yy * y + y0;


_U_s_a_g_e:

     cairoMatrixInit(xx, yx, xy, yy, x0, y0)

_A_r_g_u_m_e_n_t_s:

    'xx': [numeric]  xx component of the affine transformation

    'yx': [numeric]  yx component of the affine transformation

    'xy': [numeric]  xy component of the affine transformation

    'yy': [numeric]  yy component of the affine transformation

    'x0': [numeric]  X translation component of the affine
          transformation

    'y0': [numeric]  Y translation component of the affine
          transformation

_V_a_l_u_e:

     A list containing the following elements: 

'matrix': ['CairoMatrix']  a 'CairoMatrix'
