-  <!-- The HTML img 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.
-
-       1. If only the content-area is specified, everything is fine.
-          (If you ask for a three inch image, that's what you'll get.)
-
-       2. If only the viewport-area is provided:
-          - If scalefit=1, treat it as both the content-area and
-            the viewport-area. (If you ask for an image in a five inch
-            area, we'll make the image five inches to fill that area.)
-          - If scalefit=0, ignore the viewport-area specification.
-
-          Note: this is not quite the right semantic and has the additional
-          problem that it can result in anamorphic scaling, which scalefit
-          should never cause.
-
-       3. If both the content-area and the viewport-area is specified
-          on a graphic element, ignore the viewport-area.
-          (If you ask for a three inch image in a five inch area, we'll assume
-           it's better to give you a three inch image in an unspecified area
-           than a five inch image in a five inch area.
-
-       Relative units also cause problems. As a general rule, the stylesheets
-       are operating too early and too loosely coupled with the rendering engine
-       to know things like the current font size or the actual dimensions of
-       an image. Therefore:
-
-       1. We use a fixed size for pixels, $pixels.per.inch
-
-       2. We use a fixed size for "em"s, $points.per.em
-
-       Percentages are problematic. In the following discussion, we speak
-       of width and contentwidth, but the same issues apply to depth and
-       contentdepth
-
-       1. A width of 50% means "half of the available space for the image."
-          That's fine. But note that in HTML, this is a dynamic property and
-          the image size will vary if the browser window is resized.
-
-       2. A contentwidth of 50% means "half of the actual image width". But
-          the stylesheets have no way to assess the image's actual size. Treating
-          this as a width of 50% is one possibility, but it produces behavior
-          (dynamic scaling) that seems entirely out of character with the
-          meaning.
-
-          Instead, the stylesheets define a $nominal.image.width
-          and convert percentages to actual values based on that nominal size.
-
-       Scale can be problematic. Scale applies to the contentwidth, so
-       a scale of 50 when a contentwidth is not specified is analagous to a
-       width of 50%. (If a contentwidth is specified, the scaling factor can
-       be applied to that value and no problem exists.)
-
-       If scale is specified but contentwidth is not supplied, the
-       nominal.image.width is used to calculate a base size
-       for scaling.
-
-       Warning: as a consequence of these decisions, unless the aspect ratio
-       of your image happens to be exactly the same as (nominal width / nominal height),
-       specifying contentwidth="50%" and contentdepth="50%" is NOT going to
-       scale the way you expect (or really, the way it should).
-
-       Don't do that. In fact, a percentage value is not recommended for content
-       size at all. Use scale instead.
-
-       Finally, align and valign are troublesome. Horizontal alignment is now
-       supported by wrapping the image in a <div align="{@align}"> (in block
-       contexts!). I can't think of anything (practical) to do about vertical
-       alignment.
