[Mesa-dev] [PATCH] intel: provide a default QuerySamplesForFormat func

[Chris Forbes]

We claim to support ARB_internalformat_query on everything, but only
i965+ bothered to provide the hook -- so QueryInternalformativ() would
just explode (fail the assert in debug; segfault otherwise) on earlier
platforms.
