With very long lists, it may be advantageous to put a buffer on the drag bar to give the
user some time to actually see the scroll handle and the content. This will make the
bar less "smooth scrolling" and instead, snap to specific scroll percents. This could
be useful for the {@link DateAndTimeIndicator} style scrollbars, where you don't need to see
every single date available.

@param snapPercent percentage that the fast scroll bar should snap to.
