new color quantizer and denoiser

[denizen]

I like imagemakick software very much, but I would appreciate if you implented the new color quintizers from http://www.ximagic.com. It would dramaticaly expande the abilities of the imagemagick software.

Color quantization methods are:

-Popularity (Tom Boyle and Andy Lippman- 1978)
-Median cut (Paul S. Heckbert - 1980)
-Octree (Gervautz and Purgathofer - 1988)
-Xiaolin Wu v2 (Xiaolin Wu 1992)
-Dennis Lee v3 ( (C) Dennis Lee 1997)
-Binary Split (Orchard and Bouman 1991)
-Lloyd algorihtm (K-Means) (S.Lloyd 1957)
-Neuquant ( (C) Anthony Dekker 1994)
-SColorQ (Spatial Color Quantization - Jan Puzicha et all 1998)

All thess method and sources are widely described in internet.

Thanks once again and goodluck.
