Hi,

        I try to make viewing volume not use pfChanFOV. On IRIX 5.2, I
can make viewing volume use pfMakePerspFrust and pfChanNearFar. But on
IRIX 5.3, I can not make this viewing volume. The scene using this
volume is not offset horizon. Why? The sample program is as follows:

    chan = pfGetNewChan( pfGetPipe(0) ) ;

    pfMakePerspFrust( chan
                     , -SCREEN_WIDTH * 0.5
                     , SCREEN_WIDTH * 0.5
                     , bottom , top ) ;

    pfChanNearFar( chan, dist , far );
                :
