Circles that are Rotated, Reify Wrongly.

[tatarize]

It's possible to reify a circle incorrectly if it has a negative scale factor:

q = io.StringIO(u'''<?xml version="1.0" encoding="utf-8" ?>
                        <svg
                            width="82.475mm"
                            height="35.215mm"
                            viewBox="24.766026 -242.607513 82.475082 35.214996"
                            version="1.1"
                        >
                        <circle
                            transform="scale(1,-1)"
                            style="opacity:0.99;fill:none;stroke:#ff0000;stroke-width:0.0264584;stroke-miterlimit:4;stroke-dasharray:none"
                            r="2"
                            cx="100.41245"
                            cy="211.59723"
                            id="circle2" /></svg>
        ''')
        m = SVG.parse(q, reify=False)
        q = copy(m[0])
        r = copy(m[0])
        self.assertEqual(q, r)
        q.reify()
        r = Path(r)
        q = Path(q)
        self.assertEqual(q, r)
        r.reify()
        q.reify()
        self.assertEqual(q, r)

This test fails because in this case Path(q.reify()).reify() is different than Path(q).reify() because q.reify is flawed.
