Hi,

I've finished my proof of concept, and it seems to be working quite nicely.

I ended up needing to provide 3 strings for 3d transformations (which isn't too terrible) and I was able to implement GLSL shader support too (I don't know enough Cg script, but it should be trivial to add in).

Here's a link to the pull request:
https://github.com/imageworks/OpenColorIO/pull/329

Would be great to hear any feedback :)

Thanks,
Mark
