[Piglit] [PATCH 04/11] arb_transform_feedback2: Misc. API query tests

Ian Romanick idr at freedesktop.org
Wed Aug 21 09:07:56 PDT 2013


From: Ian Romanick <ian.d.romanick at intel.com>

This covers the transform feedback object state queries added in the
extension.  Other transform feedback queires should be covered by
existing EXT_transform_feedback tests.

NVIDIA (304.64 on GTX 260) passes this test.  AMD has not been tested.
