From 711213fb7226f25a7da4962aa7526d7265d38356 Mon Sep 17 00:00:00 2001 From: Francisco Jerez Date: Tue, 19 Jul 2016 20:29:55 -0700 Subject: [PATCH] glsl: Don't consider read-only fragment outputs to be written to. Since they cannot be written. This prevents adding fragment outputs to the OutputsWritten set that are only read from via the gl_LastFragData array but never written to.
