That's what I meant with guardband clipping: there's no actual clipping, but
the hw will still cull pixels outside the viewport. Hence it probably would be
better if draw wouldn't clip if a primitive doesn't fit into the viewport, but
fits into the (hw) guardband. (And you are right that point sprites are a bit
of a special case.)
