default void handleScrollLinesUp(int n, boolean intoScrollBack) {
		handleScrollViewportDown(n, intoScrollBack);
	}
Scroll the lines n slots up, considering only those lines in the scrolling range.

<p>
The is equivalent to scrolling the <em>viewport</em> n lines <em>down</em>. This method
exists in attempt to reflect "up" and "down" correctly in the documentation. Unfortunately,
the documentation is not always clear whether we're scrolling the viewport or the lines
themselves.

@param n the number of lines to scroll
@param intoScrollBack specifies whether the top line may flow into the scroll-back buffer
@see #handleScrollViewportDown(int)
