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