However looking at it now it seems like libepoxy is the smarter choice as long as it works correctly on Mac. For gltf as we control the code we can of course also switch from glew to libepoxy. I would need to check what collada2gltf is using. One thing to check is whether our windows code suffers from https://github.com/anholt/libepoxy#windows-issues as well as actually testing all the OpenGL features on all 3 platforms. Based on experience working OpenGL code on one system does not mean that it is not going to break somewhere else. As this change affects all the OpenGL code in our codebase this requires testing at least the OGL transitions, chart OGL (if it is still working in master), 3D models in impress (if they are still working), OGL canvas and the normal OpenGL rendering.
