-		For scrlines: threshold for lines to be scrolled.
-		    0 - Always use scrolling. (default)
-		    1 - Use full page redrawing.
-		  > 1 - If the lines to be scrolled is grater or equal to the
-			specified value, use redrawing.  Otherwise use
-			scrolling.
-
-		If you feel scrolling a page (CTRL-F) is too slow with DirectX
-		renderer, try this "scrlines" option.
-		When set it "1", Vim uses full page redrawing instead of
-		scrolling.  Redrawing a page is faster than scrolling a
-		page in some environments.
-		After that, when you feel scrolling lines (CTRL-Y) becomes
-		slow, please try "2" or greater value for this option.
-		It works threshold line number to switch scrolling to
-		redrawing.  Scrolling a few lines might be faster than
-		redrawing a page in some environments.
+		For scrlines:
+		This was used for optimizing scrolling behavior, however this
+		is now deprecated.  If specified, it is simply ignored.
