From dc0c0c176d0b4620923182aa8709084119d8f92c Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Wed, 13 Apr 2016 10:28:04 +1000 Subject: [PATCH] glsl: cache uniform values MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit These may be lowered constant arrays or uniform values that we set before linking so we need to cache the actual uniform values.
