[François T.]

those are really cool nodes though !
ToonAA and Posterize, are more Effects to me, which could be a new category
to the menu ?

> Vibrance:
> Increases the saturation but prevents clipping and oversaturation.

>
> Hue Chroma Luminance:
> Adds a Hue Chroma Luminance control,separation,combination nodes.
> The HCL Colorspace is similar in spirit to the HSV, but is based on the
> Lab Colorspace, and gives more natural results.
> Video: http://frederic.vanderessen.com/videos/node-hcl.ogv
>
> Gain:
> Increases or decreases the dynamic range of the picture.
>
> Pixelize:
> Pixelizes the picture. The size of the blocks and the method used to
> pick the
> blocks colors can be changed.
> Video: http://frederic.vanderessen.com/videos/node-pixelize.ogv
>
> Posterize:
> Reduces the number of colors in the picture. Similar to Gimp's posterize
> filter.
>
> ToonAA:
> Anti-Aliasing filter for pictures with a small number of colors. Based
> on the EPX pixel art upscaling algorithm.
