I wonder if we really need to export this function. The combo box 
currently calls it to make sure the cell view cell renderers are 
uptodate before poking at them. Maybe gtk_cell_view_get_cell_renderers
() should simply make sure that
the renderers are uptodate before returning them...

Sounds good to me, otherwise.
