I've built GTK+ 3.8.2 with X11 and Wayland backends.

Running under Wayland results in it defaulting to use the X11 backend, which
seems odd as I thought it could deduce I wanted to use Wayland from the
presence of WAYLAND_DISPLAY and not DISPLAY.  Anyway, I set GDK_BACKEND=wayland
and run gtk3-demo:

$ gtk3-demo
** (gtk3-demo:1028): WARNING **: Could not open X display

This isn't fatal but it's certainly unexpected.
