    GDK W32: Set default cursor from our own theme right away
    
    Otherwise WM-dependent default cursor is used, which does not
    match our theme. Worse, later GDK will realize that we have
    our own left_ptr cursor and will apply it after all, making
    the discrepancy even more noticeable.
