Position Routines.

getgp(x, y, z)

Gets the current graphics position in world coords.

    Fortran:
         subroutine getgp(x, y, z)
         real x, y, z

    C:
         getgp(x, y, z)
              float *x, *y, *z;

    Pascal:
         procedure GetGp(var x, y, z: real)

getgpt(x, y, z,w)

Gets the current transformed graphics position in world coords.

    Fortran:
         subroutine getgpt(x, y, z, w)
         real x, y, z, w

    C:
         getgpt(x, y, z, w)
            float *x, *y, *z, *w;

    Pascal:
         procedure GetGpT(var x, y, z, w: real)

getgp2(x, y)

Gets the current graphics position in world coords.

    Fortran:
