From 0d9f80a538a1d39206ac82c97f10253481595150 Mon Sep 17 00:00:00 2001
From: Adam Jackson <ajax@redhat.com>
Date: Tue, 7 Nov 2017 10:42:08 -0500
Subject: [PATCH] glx: Implement GLX_EXT_no_config_context (v2 squash)
This more or less ports EGL_KHR_no_config_context to GLX.
v2: Enable the extension only for those backends that support it.
Khronos: https://github.com/KhronosGroup/OpenGL-Registry/pull/102
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
