From 3f5c67d6510fe0210079ddecc0d30227a6cc4111 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 19 May 2015 16:12:45 +1000 Subject: [PATCH] softpipe: add textureOffset support. This was an oversight when GLSL1.30 was enabled, I think my misunderstanding. This fixes a bunch of tex-miplevel-selection tests under softpipe, and is required for textureGather support. I'm not sure this won't make sampling slowering, but its softpipe, correctness first and all that.
