On some Linux systems, the scaling to preserve the aspect ratio can sample the pixels outside visible region. This results in a thin grey line down some sides of the scaled picture. We add red bars over the edges to overwrite such happenings, to make the test reliable.--><videosrc="black100x100-aspect3to2.webm"style="position:absolute; left: 10px; top: 10px; z-index: 1;"></video><!-- Left side vertical. --><divstyle="position: absolute; left: 9px; top: 9px; width: 2px; height: 102px; z-index: 2; background: red;"></div><!-- Right side vertical. --><divstyle="position: absolute; left: 159px; top: 9px; width: 2px; height: 102px; z-index: 2; background: red;"></div><!-- Top horizontal bar. --><divstyle="position: absolute; left: 9px; top: 9px; width: 152px; height: 2px; z-index: 2; background: red;"></div><!-- Bottom horizontal bar. --><divstyle="position: absolute; left: 9px; top: 109px; width: 152px; height: 2px; z-index: 2; background: red;"></div></body></html>
