What dithering now does is the following: Add a random number between 0 and < 1 ontop of the computed value and clamp / round whatever. With that it would end up like this:

Code:

0,1,3,5,7,9,10
0,2,4,6,7,9,10
... and so forth. The human eye won't see the "stairs" that much, cause they are "randomized" out within a limited range.
