[Piglit] [PATCH v2 2/3] ARB_copy_image: Add a test for testing different texture target combinations
Jason Ekstrand
jason at jlekstrand.net
Mon Jun 30 10:36:01 PDT 2014
This tests all of the possible different combinations of texture targets
such as GL_TEXTURE_2D, GL_TEXTURE_CUBE_MAP, GL_TEXTURE_1D_ARRAY, etc. The
only targets not tested are GL_TEXTURE_2D_MULTISAMPLE and
GL_TEXTURE_2D_MULTISAMPLE_ARRAY but those are special.
