Actually, I suggested a line height in pixels, to conform with the
pixel measure of bitmaps. As for your markup producing a 3 point drop,
I don't think so, as you haven't specified line-height as '12pt'. 'px'
is pixel measure, but I wonder how UAs are supposed to treat values
without units. I assumed pixels, since that's default in HTML.

Yes, this is much cleaner.
Replaced elements have no baseline by default. Can they be given one?
<P>This is an inline equation:
<IMG STYLE="font-size: 100%;
height: 4em; width: 10em;
vertical-align: -5%"
SRC="equation.gif">
</P>
If so, the above would produce a graphic that is both sized and
vertically-aligned relative to the parent's font.
