Chris,
The lcms plugin is a different thing from the lcms library; GIMP's lcms
plugin just provides an interface to the lcms library (
http://www.littlecms.com/)
Try looking in the plugin to see how the plugin accesses LCMS, not to find
out what functions the plugin provides.
IIRC it basically just needs to know the input and output profiles, and be
provided pointers to source and destination buffers.
