Alan, the point of my email was specifically to test the behavior of
browsers when given an image with precisely one intrinsic dimension
and no intrinsic ratio.  JPEG and PNG always have both their intrinsic
dimensions and an intrinsic ratio.  The values I used in the ellipse
are designed specifically to show me the size of the SVG image itself
- differing values, particularly static ones, may not exercise the
same behavior, and so probably aren't useful here.

Yeah, I was using 3.6.  Unfortunately, if FF4 still fails when one
dimension is missing, then it can't exercise the behavior I'm trying
to explore here.  If you know of another way I can get FF to use an
image with one intrinsic dimension and no intrinsic ratio, let me know
so I can see what its list-style-image behavior is.

Don't worry, though - at the moment, FF simply doesn't give me any
information on the matter at hand.
