/**
 * Returns the "offsetStart" of an element, analogous to offsetLeft but
 * normalized for right-to-left environments and various browser
 * inconsistencies. This value returned can always be passed to setScrollOffset
 * to scroll to an element's left edge in a left-to-right offsetParent or
 * right edge in a right-to-left offsetParent.
 *
 * For example, here offsetStart is 10px in an LTR environment and 5px in RTL:
 *
 * <pre>
 * |          xxxxxxxxxx     |
 *  ^^^^^^^^^^   ^^^^   ^^^^^
 *     10px      elem    5px
 * </pre>
 *
 * If an element is positioned before the start of its offsetParent, the
 * startOffset may be negative.  This can be used with setScrollOffset to
 * reliably scroll to an element:
 *
 * <pre>
 * var scrollOffset = getOffsetStart(element);
 * setScrollOffset(element.offsetParent, scrollOffset);
 * </pre>
 *
 * @see setScrollOffset
 *
 * @param {?Element} element The element for which we need to determine the
 *     offsetStart position.
 * @return {number} The offsetStart for that element.
