/**
 * <p>// w  w w .ja  v a 2  s.  c om
 * Returns the <code>Point</code> at which a window should be placed to
 * center that window on the screen.
 * </p>
 * <p>
 * Some thought was taken as to whether to implement a method such as this,
 * or to simply make a method that, given a window, will center it.  It was
 * decided that it is better to not alter an object within a method.
 * </p>
 *
 * @param window The window to calculate the center point for.  This object
 *               can not be null.
 *
 * @return the <code>Point</code> at which the window should be placed to
 *         center that window on the screen.
