"Auxiliary storage qualifiers" is the new term given to "centroid",
"patch", and "sample" by GLSL 4.20/GL_ARB_shading_language_420pack.
Even though we only support "centroid", it's useful to add this now
so that all auxiliary storage qualifiers get handled in the right places
once they're eventually supported.
