The coding and general colour theory are no problem, but I'll have to
sand off some tuits to determine how to get that info from an output
profile.

And I'm not entirely convinced that the gamut would project to a
planar triangle.  The C, M and Y points would certainly be on the
enclosing curve, but that curve might be non-straight?

Especially given that profiles are measured.

Looking at such a profile via iccToXml, though, it looks like one just
needs to convert 1.0/0/0/0, 0/1.0/0/0 and 0/0/1.0/0 (otherwise scaled?)
to XYZ and thence on to Yxy.

I have master here, so I'll work on it and propose a patch.
