Description
the following piglit commit regressed several tests on SNB only:
a76e2db3 Author: Neha Bhende bhenden@vmware.com
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.

Since this test passes other platforms, it may be an SNB-specific mesa bug.
