From cae76368523b2dd25f26069b9872a8993384fa57 Mon Sep 17 00:00:00 2001 From: Pauli Nieminen Date: Tue, 12 Jun 2012 21:38:53 +0300 Subject: [PATCH] mesa/ff_shader: Fix sampler state reading Fixed function fragment shader generator was incorrectly read texture sampling state directly from texture object. To make sure that ARB_sampler_object works correctly shader generator has to use the bound sampler if one exist.
