+  <!-- 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.
