/**
 * Converts endpoint parameterization of an SVG arc to center parameterization.
 *
 * This function calculates the center (cx, cy), radii (rx, ry), start angle,
 * end angle, x-axis rotation, and sweep flag (anticlockwise) of an SVG arc path
 * given its endpoint parameterization.
 * @param x1 - The x-coordinate of the start point of the arc.
 * @param y1 - The y-coordinate of the start point of the arc.
 * @param x2 - The x-coordinate of the end point of the arc.
 * @param y2 - The y-coordinate of the end point of the arc.
 * @param largeArcFlag - The large arc flag. If true, the arc sweep will be greater than 180 degrees.
 * @param sweepFlag - The sweep flag. If true, the arc will be drawn in a "positive-angle" direction.
 * @param srx - The x-axis radius of the arc.
 * @param sry - The y-axis radius of the arc.
 * @param xAxisRotationDeg - The rotation angle in degrees of the x-axis of the ellipse relative to the x-axis of the coordinate system.
 * @returns An object containing the center coordinates, radii, start and end angles, x-axis rotation, and sweep direction of an SVG arc given its endpoint parameters.
