I am referring to this: http://www.mail-archive.com/lcms-user@lists.sourceforge.net/msg02326.html I think that the recent libclutter has all the required functionality to do this with high-level API. > The thing that jumps out to me is that the 8-bit color assumption is > baked in.

So changing to 16bit would require replacing almost everything.
