NAME
          DtCameraGetOrientationQuaternion - Get the orientation for the given
          camera in quaternions.


     SYNOPSIS
          #include <Dt.h>


          int  DtCameraGetOrientationQuaternion( int cameraID, 

                   float *xRot, float *yRot, float *zRot,float *wRot )


     DESCRIPTION
          DtCameraGetOrientationQuaternion() returns the camera orientation as a quaternion via
          the pointers to the xRot, yRot, zRot and wRot parameters, given
          the index of the camera into the camera list, via the
          cameraID parameter.  The rotation values are in radians.


     DIAGNOSTICS
          returns one on success and zero on failure.
