    /// not. The image shows two groups, each containing a red and
    /// a green rectangle which overlap. The opacity on the group is set to
    /// 128 (which is 50%). When the offscreen redirect is not used, the
    /// red rectangle can be seen through the blue rectangle as if the two
    /// rectangles were separately transparent. When the redirect is used
