     Adds 'region' to the update area for 'window'. The update area is
     the region that needs to be redrawn, or "dirty region." The call
     'gdkWindowProcessUpdates' sends one or more expose events to the
     window, which together cover the entire update area. An
     application would normally redraw the contents of 'window' in
     response to those expose events.

     gdkWindowInvalidateMaybeRecurse(object, region, child.func, user.data)

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

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

'region': ['GdkRegion']  a 'GdkRegion'

'user.data': [R object]  data passed to 'child.func'

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

     GDK will call 'gdkWindowProcessAllUpdates' on your behalf whenever
     your program returns to the main loop and becomes idle, so
     normally there's no need to do that manually, you just need to
     invalidate regions that you know should be redrawn.

     The 'child.func' parameter controls whether the region of each
     child window that intersects 'region' will also be invalidated.
     Only children for which 'child.func' returns TRUE will have the
     area invalidated.
