gtk+3: Do not try to initialize GL without libgl
Gdk initialization ends up calling epoxy GLX api, which calls exit() if libGL.so.1 is not present. In practice this prevents all GTK+ applications from starting if GLX is not present. If opengl and x11 distro features are set, make gtk+3 RDEPEND on libgl. If opengl and x11 distro features are not set, use #ifdef to prevent the GL initialization. Remove libgl dependency from gtk3-demo: it can now run without libgl (although trying to run the glarea demo will exit in that case).

+Subject: [PATCH] Do not try to initialize GL without libGL
+
+_gdk_x11_screen_update_visuals_for_gl() will end up calling epoxys
+GLX api which will exit() if libGL.so.1 is not present. We do not
+want that to happen and we don't want every app to have to set
+"GDK_GL=disabled" environment variable: so use #ifdef set based on
+opengl distro feature.
+
+Upstream is not interested in the fix as it is: Either epoxy should be
+fixed (to not exit) or GTK+ possibly could do some additional probing
+before calling epoxy APIs.
+
+Upstream-Status: Denied
