Stores the front clipping plane offset from the target plane for the current
viewport, in drawing units.
The front clipping and front clip not at eye bitcodes in VIEWMODE are on. The
FRONTZ value is the last front clipping plane value set current with the
CAMERA, DVIEW, or 3DCLIP command. The distance of the front clipping
plane from the camera point is found by subtracting FRONTZ from the
camera-to-target distance.
