The "cairo way" of specifying an ellipse is usually to just provide a
circle and a transformation. So perhaps David's "two ellipses" are
actually just two circles modified by the same transformations.

If so, the only distinction I see between that and the images you have
is the presence of an inner radius, (which would presumably be treated
with the same extend attribute as the outer radius).
