[Piglit] [PATCH v3 1/5] spec/ARB_copy_image: Add a simple ARB_copy_image test
Jason Ekstrand

Thu Aug 7 17:35:07 PDT 2014
This is a simple sanity test for the ARB_copy_image extension. This tests
tests the different combinations of textures and renderbuffers for intputs
and outputs to glCopyTexSubImage.
v2: Incorperated comments from Brian Paul
v3: Also copy from the texture back onto itself to test yet another path
