Are there still objections, or can this (using Olaf's color model) be 
added to KColorUtils?

(If that's ok, can darken/lighten using this model also be added? These 
would be used by color shading (tentatively KColorShades), see 
http://permalink.gmane.org/gmane.comp.kde.devel.core/43099, and of 
course by anyone else wanting them...)
