ScrollBy is an overridden method in TCustomMemo used to scroll the visible area for the control by the specified amounts.
DeltaX and DeltaY contain the number of pixels the content in the control is scrolled. DeltaX is applied to the horizontal position. DeltaY is applied to the vertical position. A positive value means that he control scrolls towards its bottom or right (respectively). Conversely, a negative value scrolls the content towards its top or left.
ScrollBy calls the ScrollBy_WS method in the ancestor class. It essentially replaces the method in the ancestor with the same name, and does not call the inherited method.
