-<para>The HTML <tag>img</tag> element only supports the notion
-of content-area scaling; it doesn't support the distinction between a
-content-area and a viewport-area, so we have to make some compromises.</para>
-
-<para>If <parameter>make.graphic.viewport</parameter> is non-zero, a table
-will be used to frame the image. This creates an effective viewport-area.
-</para>
-
-<para>Tables and alignment don't work together, so this parameter is ignored
-if alignment is specified on an image.</para>
