[Piglit] [PATCH 01/13] Add a small API test for GLSL 1.30 exposing the texel offset limit queries.

[Eric Anholt]

The queries appear in the GL 3.0 spec, and are mentioned to be
supported in the GLSL 1.30 spec.  The GLSL 1.30 spec doesn't list the
minimum maximum and the maximum minimum we're testing here, which
somes from 3.0.
