<pre>the following piglit commit regressed several tests on SNB only:
a76e2db38179a7923745b4f9b15fd94198e8cfab
Author: Neha Bhende <<a href="mailto:bhenden@vmware.com">bhenden@vmware.com</a>>
textureGather: correct expected result for
GL_MAX_PROGRAM_TEXTURE_GATHER_COMPONENTS_ARB = 1
Expected results were with respect to
GL_MAX_PROGRAM_TEXTURE_GATHER_COMPONENTS_ARB = 4. This patch fixes
it for GL_MAX_PROGRAM_TEXTURE_GATHER_COMPONENTS_ARB = 1 as well.
Reviewed-by: Brian Paul <<a href="mailto:brianp@vmware.com">brianp@vmware.com</a>>
