From 34336931fa2993b06df87d68548baf2129aca217 Mon Sep 17 00:00:00 2001
From: Robert Osfield <robert@openscenegraph.com>
Date: Mon, 27 Nov 2017 18:28:15 +0000
Subject: [PATCH] Deprecated the osg::Shader::reaDShaderFile() and
 osg::Shader::loadShaderSourceFromFile() methods. Programmers should use
 osgDB::readRefShaderFile()/readShaderFile() instead.
