about

nx_rd_intra_gate.nx -- MEASURES the rate-distortion gain of intra prediction: code one structured frame two ways (naive pixels-128 vs neighbour-predicted, raster order) at the same QP and compare bytes + PSNR. Proves V-R7 shifts the RD curve left (fewer bytes at equal quality). Composes nx_intra+nx_vtransform+nx_ventropy+nx_quality_metric.
