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

     Sets a 'GdkWindow' as composited, or unsets it. Composited 
     windows do not automatically have their contents drawn to  the
     screen. Drawing is redirected to an offscreen buffer  and an
     expose event is emitted on the parent of the composited  window.
     It is the responsibility of the parent's expose handler to
     manually merge the off-screen content onto the screen in whatever
     way it sees fit. See  for an example.

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

     gdkWindowSetComposited(object, composited)

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

'object': ['GdkWindow']  a 'GdkWindow'

'composited': [logical] 'TRUE' to set the window as composited

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

     It only makes sense for child windows to be composited; see
     'gdkWindowSetOpacity' if you need translucent toplevel windows.

     An additional effect of this call is that the area of this window
     is no longer clipped from regions marked for invalidation on its
     parent. Draws done on the parent window are also no longer clipped
     by the child.

     This call is only supported on some systems (currently, only X11
     with new enough Xcomposite and Xdamage extensions).  You must call
     'gdkDisplaySupportsComposite' to check if setting a window as
     composited is supported before attempting to do so.  

     Since  2.12
