We can support this, but I think we would do this with an arc class
rather than an ellipse class, and write a special case class that is
viewlim aware.   A simple example of a line that has analogous
behavior is examples/clippedline.py, which clips the points outside
the viewport and draws in a different style according to the
resolution of the viewlim.   The reason I think it would be preferable
to use an arc here is because we won't have to worry about filling the
thing when we only approximate a section of it.  You could feed in a
360 degree elliptical arc and then zoom into a portion of it.

With the 8 point ellipse as is, and the addition of an arc class that
does 4 or 8 point approximation within the zoom limits, should that
serve your requirements?
