Should these have ARB_robustness-style buffer size parameters?
Hmm... many queries don't have size parameters, even with
ARB_robustness, because the amount of data returned is always knowable
in advance. See issue #6 in that spec. In the (as yet unposted) piglit
tests, I have a couple tests that make sure the queries don't return too
much data.
Adding a size parameter might make it more future proof, but I'm having
trouble even imagining a query that would be appropriate for this
extension and have a variable payload. Either way, I can add it as an
issue.
