SVN commit 1106979 by cgilles:

compute all noise on YCbCr color space. Drop HSL color space. 

To check shadows, midtone, and highlight area of image, use Luma chanel from
YUV instead Lightness chanel from HSL.

Fix all glitch color generated aroung shadows and hightlight pixels to clamp
properly all values adjusted with graininess.
