48 * Sampler code generation interface.
50 * Although texture sampling is a requirement for TGSI translation, it is
51 * a very different problem with several different approaches to it. This
52 * structure establishes an interface for texture sampling code generation, so
53 * that we can easily use different texture sampling strategies.
