<rdar://problem/4966982> 64-bit: In a unordered list, TYPE=DISC and TYPE=CIRCLE attribute values are ignored

        We need to draw our full-circle arcs counter-clockwise, since a clockwise arc from 0 to 2π is no arc at all!
        This only worked on 32-bit due to a rounding error in CoreGraphics, causing it to draw a full circle anyway.

        (WebCore::GraphicsContext::drawEllipse):
