From: Erik Faye-Lund Date: Fri, 5 Jul 2019 14:21:45 +0000 (+0200) Subject: gallium: give vertex-shader saturate its own cap X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=21de1bf24ba6d65f1566c3b8b742636587c39697;p=mesa.git gallium: give vertex-shader saturate its own cap Shader Model 3.0 is a big promise to make to the state-tracker, and for instance mobile hardware might support vertex-shader saturate but not some of the other features of SM3. So let's give this its own cap for simplicity.
