_c_a_i_r_o_S_e_t_S_o_u_r_c_e

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

     Sets the source pattern within 'cr' to 'source'. This pattern will
     then be used for any subsequent drawing operation until a new
     source pattern is set.

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

     cairoSetSource(cr, source)

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

    'cr': ['Cairo']  a cairo context

'source': ['CairoPattern']  a 'CairoPattern' to be used as the source
          for subsequent drawing operations.

_D_e_t_a_i_l_s:

     Note: The pattern's transformation matrix will be locked to the
     user space in effect at the time of 'cairoSetSource'. This means
     that further modifications of the current transformation matrix
     will not affect the source pattern. See 'cairoPatternSetMatrix'.

     XXX: I'd also like to direct the reader's attention to some
     (not-yet-written) section on cairo's imaging model. How would I do
     that if such a section existed? (cworth).
