        in multiprocess case, use: pfPWinConfigFunc(pw,OpenPipeWindow);
        and pfConfigPWin(pw); you can do pfOpenPWin() in function
        OpenPipeWindow.

        is it zero or some number? then move win=pfGetPWinWSWindow(pw);
        and fprintf(stderr,"win is 0x%x\n",win); to OpenPipeWindow(),
        try PFMP_APPCULLDRAW, PFMP_APP_CULLDRAW.

key problem is pfGetPWinWSWindow doesn't work in APP process when multiprocess
case. man page say it works, but it doesn't. it works in DRAW process.
Hope this helps.
