From 1bd623316913fdefa3749809420db27291ef9f0e Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 7 Nov 2013 14:39:23 -0800 Subject: [PATCH] glsl: Enable dFdx, dFdy, and fwidth by default in GLSL ES 3.00. Previously, we only exposed them in desktop GL or with: #extension GL_OES_standard_derivatives : enable GLSL ES 3.00 includes these without an extension, so we need to expose them by default. Note that the above #extension line results in an error or desktop GL, so we don't need to worry about this.
