I'm not sure this is really a good idea (at least for llvmpipe). At least the number of layers used internally is wrong (fb_max_layer is going to be ~0 as it is always derived from the attached buffrs). I suppose though it might not actually matter. But I'm not sure if there's really any point in this extension without images - while I initially thought it wouldn't be able to do anything this isn't quite true as there is indeed one side effect of fs possible even without images, which is query results (such as occlusion queries, which is what piglit uses). I think though just about all practical use cases really would require image support, so I'm not convinced exposing this just because we can is worth it. But OTOH why not...
