From b53a33feef2595fc71fadafa5857d5482514a724 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 12 Nov 2016 13:17:27 -0500 Subject: [PATCH] swr: [rasterizer jitter] don't bother quantizing unused channels In a BGR10X2 or BGR5X1 situation, there's no need to try to quantize the X channel - the default will have the proper quantization required.
