Interface to a polyqualdratic Bézier segment. A polyqualdratic Bézier segment describes a set of quadratic Bézier curves from the starting point defined in the IDOMPathFigure, or from the end point of the previous segment, through a set of vertices, using specified control points. The Points attribute stores an off-curve control point (x2n-1, y2n-1) followed by the end point (x2n, y2n) for each quadratic Bézier curve (where n represents the quadratic Bézier curve).
