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

     Applies rotation by 'radians' to the transformation in 'matrix'.
     The effect of the new transformation is to first rotate the
     coordinates by 'radians', then apply the original transformation
     to the coordinates.

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

     cairoMatrixRotate(matrix, radians)

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

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

'radians': [numeric]  angle of rotation, in radians. The direction of
          rotation is defined such that positive angles rotate in the
          direction from the positive X axis toward the positive Y
          axis. With the default axis orientation of cairo, positive
          angles rotate in a clockwise direction.
