     If you bypass the GDK layer and use windowing system primitives to
     draw directly onto a 'GdkWindow', then you need to deal with two
     details: there may be an offset between GDK coordinates and
     windowing system coordinates, and GDK may have redirected drawing
     to a offscreen pixmap as the result of a
     'gdkWindowBeginPaintRegion' calls. This function allows retrieving
     the information you need to compensate for these effects.

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

     gdkWindowGetInternalPaintInfo(object)

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

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

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

     This function exposes details of the GDK implementation, and is
     thus likely to change in future releases of GDK.

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

     A list containing the following elements: 

'real.drawable': ['GdkDrawable']  location to store the drawable to
          which drawing should be  done.

'x.offset': [integer]  location to store the X offset between
          coordinates in 'window', and the underlying window system
          primitive coordinates for  *'real.drawable'.

'y.offset': [integer]  location to store the Y offset between
          coordinates in 'window', and the underlying window system
          primitive coordinates for *'real.drawable'.
