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

     Applies a shape mask to 'window'. Pixels in 'window' corresponding
     to set bits in the 'mask' will be visible; pixels in 'window'
     corresponding to unset bits in the 'mask' will be transparent.
     This gives a non-rectangular window.

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

     gdkWindowShapeCombineMask(object, shape.mask = NULL, offset.x, offset.y)

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

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

'shape.mask': ['GdkBitmap']  shape mask

'offset.x': [integer]  X position of shape mask with respect to
          'window'

'offset.y': [integer]  Y position of shape mask with respect to
          'window'

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

     If 'mask' is 'NULL', the shape mask will be unset, and the 'x'/'y'
     parameters are not used.

     On the X11 platform, this uses an X server extension which is
     widely available on most common platforms, but not available on
     very old X servers, and occasionally the implementation will be
     buggy. On servers without the shape extension, this function will
     do nothing.

     This function works on both toplevel and child windows.
