Remarks
When paging down, this method scrolls the view so that the line below the last fully-visible line is even with the top of the view. When paging up, this method scrolls the view so that the line above the first fully visible line is even with or slightly above the bottom of the view. It may be shifted up to prevent a partially-visible line at the top of the view. If there are no fully-visible lines in the view because the view is too short, the view is scrolled by exactly the viewport height. The view cannot be scrolled so that there is a gap between the top of the view and the first line of text.
