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

     Calculates the intersection of two rectangles. It is allowed for
     'dest' to be the same as either 'src1' or 'src2'. If the
     rectangles  do not intersect, 'dest''s width and height is set to
     0 and its x  and y values are undefined. If you are only
     interested in whether the rectangles intersect, but not in the
     intersecting area itself, pass 'NULL' for 'dest'.

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

     gdkRectangleIntersect(src1, src2)

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

  'src1': ['GdkRectangle']  a 'GdkRectangle'

  'src2': ['GdkRectangle']  a 'GdkRectangle'

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

     A list containing the following elements: 

  retval: [logical] 'TRUE' if the rectangles intersect.

  'dest': ['GdkRectangle']  return location for the intersection of
          'src1' and 'src2', or 'NULL'
