First try to implement Graininess size support


Look there :


Attached patch add support and experimental concept to adjust graininess size.
Of course, like you can see, I use the same adjustment for all pixel from the
matrix, and result is a mosaicked image. 

The pixel on the top left is the reference to compute nRand. All other pixels
from the matrix are adjusted with this value. 

The start idea is there. Instead to use same value for each matrix points, we
must compute alternative random values in the matrix loop one by one. These
alternative nRand must be near of the reference one.

What do you think about this concept ?
