Brian, these operators have been defined in the Documents/colorsep.ps
proposal on our server.  They're not in the document itself, but rather
they are in the PostScript code that images the document. These operators
were defined and used to create the examples in the document.

With the advent of Level II and other changes, we didn't feel that it was
appropriate to make these definitions available in a formal sense. They
may change in the future.  When we have got a solid definition for these
things, we'll make them available properly.
