Subject: [PATCH] Apply workaround patch for compiling against nvidia headers
 posted as #2819332 by larryhaja. It reports that the patch fixes compilation
 for him and it doesn't break it for me so hopefully there aren't regressions.
 Said that i've tried to define GL_GLEXT_PROTOTYPES at configure time but it
 breaks compilation and making OGLRender.cpp:133 not optional looks way more
 risky.
