From a21df965075f6fa1bf27039490ad65b9f78548e6 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sat, 24 Mar 2012 13:36:17 +0000 Subject: [PATCH] st/mesa: add ARB_blend_func_extended support to state tracker. This adds the blend mode mapping, it also uses the var->index in the glsl to tgsi convertor - this is the other half of my using 4 in the GLSL compiler.
