Method scrollTo

src/cdk/scrolling/scrollable.ts:88–127

* Scrolls to the specified offsets. This is a normalized version of the browser's native scrollTo * method, since browsers are not consistent about what scrollLeft means in RTL. For this method * left and right always refer to the left and right side of the scrolling container irrespective

(options: ExtendedScrollToOptions)

   * @param options specified the offsets to scroll to.
