+Subject: [PATCH] test/glx_public_api_core: Fail softer if core contexts aren't
+ available
+
+If you've built Mesa with --disable-texture-float, and try to run the
+tests against Xvfb, glx_public_api_core will fail: creating a direct
+context with llvmpipe will fail because you don't have
+ARB_texture_float, and the internal fallback to an indirect context will
+fail because indirect only supports through 1.4. So the server will
+throw GLXBadFBConfig at you to say "I don't support core contexts",
+which we should interpret as a skip not a failure.
