+From f6c2eeaad968b1ad0ebef7fad79eb5f01305a6e3 Mon Sep 17 00:00:00 2001
+From: Awais Belal <awais_belal@mentor.com>
+Date: Wed, 5 Sep 2018 11:43:07 +0500
+Subject: [PATCH 5/5] demos/cube*: use absolute location for data files
+
+If absolute locations are not used here the demo
+looks for texture files in a haphazard way and
+can only be launched from the same directory.
+This allows running the demo from anywhere and
+consolidate any data files that are needed.
