Comment 5 for bug 210109

That's what I had in mind. What, apart from the arcs, doesn't work on circles or ellipses?
If you perform path operations on two objects, obviously the result is a path. Currently I can use a circle element in a compound operation, like combine, which turns the circle into a path, punching a hole in another shape. I doubt that circle could be made back into a Circle element if broken apart, but what would be neat is if you've made an arc, and you have your Sodipodi attributes, if you close the arc again, it can be made back into a circle or ellipse element.
