[Piglit] [PATCH] OES_required_internalformat: Add a test for renderbuffer sizing.

Eric Anholt eric at anholt.net
Tue May 2 19:20:35 UTC 2017


dEQP provides some coverage for texture and renderbuffer formats being
supported, but doesn't test that the storage reports appropriate
sizes.  We can't test textures easily becase GetTexLevelParameter
doesn't exist, but GetRenderbufferParameter can let us test
renderbuffers at least.
