multi-res: disable intra on forced ref frames If a reference frame is forced because of low dissimilarity, then shut off the search of intra modes. This change has mixed results. On one clip (QVGA), it hurt quality by ~1.5% with negligible speed impact. On another (VGA) it had negligible affect on quality, but a ~0.2% speed impact.
