<Quantity>
Required. Amount of pixels to shift the background plane.
<Cell>
Required if the scroll mode is HSCROLL_CELL, HSCROLL_LINE, or VSCROLL_2CELL.

If the scroll mode is HSCROLL_CELL, then <Cell> indicates which horizontal cell will be scrolled.

If the scroll mode is HSCROLL_LINE, then <Cell> indicates which line to scroll.
