From a2db6b4254462c62fe60dcc62645da6901986690 Mon Sep 17 00:00:00 2001 From: Danylo Piliaiev Date: Wed, 5 Sep 2018 15:26:48 +0300 Subject: [PATCH] glsl: Make invariant outputs in ES fragment shader not to cause error In all GLSL ES versions output variables in fragment shader are allowed to be invariant. From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 1.00 spec: "Only the following variables may be declared as invariant: ... - Built-in special variables output from the fragment shader." From Section 4.6.1 ("The Invariant Qualifier") GLSL ES 3.00 spec: "Only variables output from a shader can be candidates for invariance."
