From 66ee6661e9968ea146d2ad0d606e1a35a17587dd Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Fri, 5 Jul 2019 15:46:38 +0200 Subject: gallium: give fragment-shader texture-lod its own cap MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Shader Model 3.0 is a big promise to make to the state-tracker, and for instance mobile hardware might support texture lod but not some of the other features of SM3. So let's give this its own cap for simplicity.
