From bb430ced7fb2aa26007637a0907d886716e8ddd6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 26 Mar 2012 14:04:48 -0700 Subject: [PATCH] glsl: Add texelFetch(*samplerBuffer) entrypoints to GLSL 1.40. Fix texelFetch(sampler2DRect) and textureSize(samplerBuffer) generation to not reference a LOD at the same time because it's easier than not fixing it.
