An inline graphic is displayed, by default, with its lower edge on the
baseline of the text surrounding the graphic. If the surrounding text
changes size or font face, the location of the baseline could move, but
the graphic would still have its lower edge on the baseline. Since I am
setting the vertical-align property to the negative of the distance
from the graphic's lower edge to the internal baseline of the image -
the distance needs to be a fixed distance.
There is a good argument for expressing that distance in pixels, but I
really don't see the case for em or %.
