gl.render offset(offaxis) message? Perspective correction...

    What is the message and way to use it for renderind an offset (offaxis) gl view? (camera is not moving!!!) after web search I thought perhaps it's : glTranslated. I also remenber (years ago that gl had such function)
    I'll use it to simulate the offaxis projection viewpoint of video beamer. Generally 50/70% down the central vertical axis.
    Example:I use a 1024x1536 window of a render context, and display only the half upper part to simulate a video beamer(w. 50% offset). It would be better if i could work with a 1024x768 window of an offsetted render
    thanks
