* For the given scrollLeft value this method returns the scrollLeft value as understood by the current browser in RTL mode.
* This value is specific to the given DOM element, as the computation may involve its dimensions.
*
* So when oDomRef should be scrolled 2px from the leftmost position, the number "2" must be given as <code>iNormalizedScrollLeft</code>
* and the result of this method (which may be a large or even negative number, depending on the browser) can then be set as
* <code>oDomRef.scrollLeft</code> to achieve the desired (cross-browser-consistent) scrolling position.
*
* This method does no scrolling on its own, it only calculates the value to set (so it can also be used for animations).
*
* @function
* @since 1.58
* @param {int} iNormalizedScrollLeft The distance from the leftmost position to which the element should be scrolled
* @param {Element} oDomRef The DOM Element to which scrollLeft will be applied
* @return {int} The scroll position that must be set for the DOM element
