From 58709d36d73419c21b899d4b9d08a4a82a2cc28b Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 8 Jul 2016 12:00:30 -0700 Subject: [PATCH] glsl: Add extension plumbing for OES/EXT_tessellation_shader. This adds the #extension directive support, built-in #defines, lexer keyword support, and updates has_tessellation_shader().
