  24 <para>The HTML <tag>img</tag> element only supports the notion
  25 of content-area scaling; it doesn't support the distinction between a
  26 content-area and a viewport-area, so we have to make some compromises.</para>
  27
  28 <para>If <parameter>make.graphic.viewport</parameter> is non-zero, a table
  29 will be used to frame the image. This creates an effective viewport-area.

  32 <para>Tables and alignment don't work together, so this parameter is ignored
