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

     Like 'cairoSurfaceMarkDirty', but drawing has been done only to
     the specified rectangle, so that cairo can retain cached contents
     for other parts of the surface.

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

     cairoSurfaceMarkDirtyRectangle(surface, x, y, width, height)

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

'surface': ['CairoSurface']  a 'CairoSurface'

     'x': [integer]  X coordinate of dirty rectangle

     'y': [integer]  Y coordinate of dirty rectangle

 'width': [integer]  width of dirty rectangle

'height': [integer]  height of dirty rectangle

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

     Any cached clip set on the surface will be reset by this function,
     to make sure that future cairo calls have the clip set that they
     expect.
