Thanks for the PR.

This looks good to me.

(Note that this might be conflicting with #6675 it if it merged.)

[teknalb]

Thanks, this should've been in winit long ago, at least it doesn't conflict with it when they fix it.
Maybe #6675 should remove this if merged and contradicts this but I think non-resizable window should still not enable the maximize button :)

Oh, I see that I have dummy user (optimus) attached to this commit, do I need submit a new commit/pull request using only my github user or this will do?

[ogoffart]

This will do.
