Never mind.  I see the problem... The site is using:

        .quote
        {
                border-color: silver;
                border-width: 1px;
                border-style: double;
        }

For border-style "double" correct rendering is:

  "The border is two solid lines. The sum of the two lines and the space between 
   them equals the value of 'border-width'."
    (from http://www.w3.org/TR/REC-CSS2/box.html#border-style-properties)

It's obviously impossible to actually draw a "double" 1px border... over to
layout to decide what to do with this.  Should we just fall back to "solid" for
1px "double" borders?
