Blah, this regresses ARB_framebuffer_no_attachments for 2 reasons --
(a) This is in a GL_CORE / GLES31 section, but this enum should be
available in compat
(b) In compat, there is no geometry shader accessible. Really this
should be something like ARB_no_fb && (mesa_is_desktop_gl ||
mesa_has_OES_geometry)?
I'm seeing 'bin/arb_framebuffer_no_attachments-minmax -fbo -auto' fail
because of this... did it not regress for you? The test runs in a
compat context...
