/** Allows to specify initial position of the actor on the stage. Expends a float value (absolute position).
 *
 * <p>
 * Note that it works MOSTLY if the actor is a root - has no parent and is attached to a stage by the parser, not
 * manually. Most groups will override this setting. If used on a root actor, it can accept float values (absolute
 * position) or a float ending with a '%' (for example, "0.5%"). If a percent is passed, it will set the Y position as a
 * percent of stage's initial height. For the most predictable results, set both x and y attributes.
 *
 * <p>
 * By default, mapped to "y".
