// Notes: This utilitycomputes the Bezier approximation for an elliptical arc as it is defined
// in the SVG arc spec. The ellipse from which the arc is carved is axis-aligned in its
// own coordinates, and defined there by its x and y radii. The rotation angle defines
// how the ellipse's axes are rotated relative to our x axis. The start and end points
// define one of 4 possible arcs; the sweep and large-arc flags determine which one of
// these arcs will be chosen. See SVG spec for details.
//
// Returning pieces = 0 indicates a line instead of an arc
// pieces = -1 indicates that the arc degenerates to a point
