No, it doesn't. Without your patch, Mesa successfully compiles the
following shader:
`centroid` has never been an interpolation qualifier, though.
In GLSL 1.20, `centroid varying` is a storage qualifier.
In GLSL 1.30, `centroid in`, `centroid out` are added as storage qualifiers.
In GLSL 4.20 (or ARB_shading_language_420pack), `centroid`, `sample`,
and `patch` are split from `in`
Place centroid keyword as an interpolation qualifier.
Previously was a storage qualifier. Fixes front end
to accept input of the form "centroid in type variable"
