[Piglit] [PATCH] glsl-version-define-130: New test for glsl 1.30 existence and __VERSION__ reflecting glsl 1.30.

[jian.j.zhao at intel.com]

From: Jian Zhao <jian.j.zhao at intel.com>

According to the glsl spec page 7:
     "This document specifies only version 1.30 of the OpenGL
     Shading Language. It requires __VERSION__ to substitute
     130, and requires #version to accept only 130. If #version
     is declared with 110 or 120, the language accepted is a
     previous version of the shading language, which will be
     supported depending on the version and type of context in
     the OpenGL API."

v2: use in and out instead of some deprecated variables.
