    // This is a bit silly, but the thing is that a buffer blit takes place on this
    // pass, and if you do a buffer blit on a pass that outputs to lower-resolution,
    // it only blits a smaller portion of the backbuffer that occupies that number of
    // pixels.  So we need a dummy no-op pass that is full-res in order to blit everything.
