-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

-Subject: [PATCH] Add --disable-opengl configure option
-
---disable-opengl will remove the dependency on libepoxy and on the
-OpenGL APIs. This is useful for those who want to keep using gtk+3
-without the "opengl" distro feature.
-
-GtkGLArea is still part of the API (it just doesn't work) even when
-OpenGL is disabled. GdkX11GLContext was removed from the Gtk API
-completely: that object exposes GL API elements so it had to be at
-the very least modified.
-
-The patch is _not_ great from a maintenance point of view and
-modifying the library API is also a fairly nasty thing to do.
-Next long term release (4.0) will require alternative solutions
-as it actually will depend on OpenGL.
-

+From: Jussi Kukkonen <jussi.kukkonen@intel.com>
+Date: Fri, 16 Oct 2015 16:35:16 +0300
+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
