Draws an elliptical arc from the current point to (x, y) using relative
coordinates. The size and orientation of the ellipse are defined by two
radii (rx, ry) and an xAxisRotation, which indicates how the ellipse as
a whole is rotated relative to the current coordinate system. The center
(cx, cy) of the ellipse is calculated automatically to satisfy the
constraints imposed by the other parameters. largeArcFlag and sweepFlag
contribute to the automatic calculations and help determine how the arc
is drawn. If largeArcFlag is TRUE then draw the larger of the available
arcs. If sweepFlag is true, then draw the arc matching a clock-wise
rotation.
