locally I have our opengl slideshow transitions working[1] under gtk3 on wayland and I'd like to merge this to master. The gtk3 part is fairly trivial as it turns out. But glew doesn't work under wayland. epoxy does however (and it's what gtk3 itself uses). epoxy claims to support all of our platforms. One little snag is that libgltf uses glew in its headers, so I had to patch it to port it over to epoxy. Is there any objection to the principle of dropping glew in favour of epoxy, or do I need to go down a more complicated conditional approach. Or any other snags I haven't considered ? C. [1] well some of them anyway
