Basically, we use a private instance of the 'draw' module for doing selection/feedback. It would be nice to use the transform_feedback hardware feature, but it's defined as happening pre-clip and we want post-clipped primitives. Also, there's concerns about the efficiency of using the hardware for this anyway.
Authors: Brian Paul This is actually used for both feedback and selection.
