To see the GL version, renderer and extensions strings under Wayland. I
couldn't find any other tool to do just this.

This was more of a "get to know Wayland" thing for me rather than
implementing something generally useful.

Still, I don't really understand why you say it's overkill, or the
window system comment. You cannot run any of the existing {glx,es2}info
tools under Wayland, because you have to create a display and a
surface/window before calling EGL. And without eglMakeCurrent(), the
strings are empty.
