From 36171af399e24095a0836e05a519a19e161a278e Mon Sep 17 00:00:00 2001 From: Adam Treat Date: Sat, 2 Dec 2017 10:36:12 -0500 Subject: Make use of our egl convenience code for QNX QPA This fixes various problems that occur because the current egl context assumes OpenGL ES 2.0 and does not support newer versions of ES.
