It is necessary to manually set the GL version to 3.0 in order to run
Piglit tests using glGetUniform*().
This patch allows one to override the version of the OpenGL context by
setting the environment variable MESA_GL_VERSION_OVERRIDE.

The description is a little inaccurate. I'd say something like "setting this
variable changes the value returned by glGetString(GL_VERSION). Mesa will not really
implement all the features of the given version if it's higher than what's normally
reported.

Ok. I'll change the description to what you suggested.
