I wholly agree. Let's move forward in implementing 3.2. We need to do that
regardless the outcome of Ian's proposed questions. If additional evidence
comes to light that proves ARB_geometry_shader4 would be useful without
GL 3.2 (which I doubt), then nothing prevents us from implementing that
atop our then-existing support for the 3.2 variant of GS.
