The Hopgood etal book you cite contains a section on levels.  See section
8.6, page 124.  The 2nd edition of that book doesn't contain any new 
information on levels.  You might want to check another GKS reference book:
"Computer Graphics Programming: GKS - The Graphics Standarad", G. Enderle,
K. Kansy, G. Pfaff, Springer-Verlag, 1984.  There is a newer edition than
this.  In the 1984 edition, Chapter 2, pgs 86-98 address the levels of GKS.
