-**  CIP X,Y given Fukushima-Williams bias-precession-nutation angles.
-**
-**  Given:
-**     gamb     double    F-W angle gamma_bar (radians)
-**     phib     double    F-W angle phi_bar (radians)
-**     psi      double    F-W angle psi (radians)
-**     eps      double    F-W angle epsilon (radians)
-**
-**  Returned:
-**     x,y      double    CIP unit vector X,Y
-**
-**  Notes:
-**
-**  1) Naming the following points:
-**
-**           e = J2000.0 ecliptic pole,
-**           p = GCRS pole
-**           E = ecliptic pole of date,
-**     and   P = CIP,
-**
-**     the four Fukushima-Williams angles are as follows:
-**
-**        gamb = gamma = epE
-**        phib = phi = pE
-**        psi = psi = pEP
-**        eps = epsilon = EP
-**
-**  2) The matrix representing the combined effects of frame bias,
-**     precession and nutation is:
-**
-**        NxPxB = R_1(-epsA).R_3(-psi).R_1(phib).R_3(gamb)
-**
-**     The returned values x,y are elements [2][0] and [2][1] of the
-**     matrix.  Near J2000.0, they are essentially angles in radians.
-**
-**  Called:
-**     eraFw2m      F-W angles to r-matrix
-**     eraBpn2xy    extract CIP X,Y coordinates from NPB matrix

-**  The ERFA version is intended to retain identical functionality to

-**  Although the intent is to replicate the SOFA API (other than
