    transform-root-bg-001.html, except that it uses scale(0.5) instead of
    scale(-1).  It also specifies a transform-origin, because the default of
    50% 50% wouldn't work well with the way the reference image is constructed.">

         * at a multiple of 100px.  Otherwise after the transform, the shrunken

         * match the ref (since the background here is positioned at the left).
