Scroll to an absolute row offset from the top of the scrollable
area. Row 0 is the top of the scrollback and the requested row
becomes the first visible row of the viewport. The value is
clamped so the viewport never scrolls beyond the top of the
active area. If the terminal has no scrollback (e.g. the
alternate screen is active), the viewport always remains on the
active area.
