    Don't draw to unviewable windows
    
    The scrolling and region moving code needs to avoid drawing when the
    window is mapped, which it did. However, it also needs to avoid
    drawing when any of its parents are not mapped, which it didn't so
    switch to using gdk_window_is_viewable().
    
    This fixes the index rendering in evolution (#588169)
