[Piglit] [PATCH] glsl-1.40: Expect shadow comparison alpha to be 1.0

[Ian Romanick]

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

Appendix E.1 (Profiles and Deprecated Features of OpenGL 3.0) of the
OpenGL 3.1 spec says:

    • Depth texture mode - DEPTH TEXTURE MODE. Section 3.9.14 is to be
      changed so that r is returned to texture samplers directly, and
      the OpenGL Shading Language 1.30 Specification is to be changed so
      that (r, r, r, 1) is always returned from depth texture samplers
      in this case.
