    In our application, we suspend portions of our cull and draw
processing depending on the state of a global flag. e.g.,

void CullFunc(pfChannel * chan, void *data)
{
    /* don't bother if we're suspended */
    if (ViewState->suspendFlag)
        return;

    PreCull(chan, data);
    pfCull();
    PostCull(chan, data);
}

void DrawFunc(pfChannel *chan, void *data)
{
    /* only bother with these if we're not suspended */
    if (!ViewState->suspendFlag) {
        PreDraw(chan, data);
        pfDraw();
    }
    PostDraw(chan, data); /* always process input */
}

THE QUESTION:
With respect to setting the state of our global flag,
in an application which uses pfuGLXWinopen (), is there a preferred
method to test whether the top level window has been iconified or not?

A code snippet would be appreciated.

Thanks in advance,

Rob
