John Stiles f47cfa8be5 Implement compile-time optimization for refract().
$genType refract($genType I, $genType N, float eta);
$genHType refract($genHType I, $genHType N, half eta);

The half form of refract was originally taking a `float eta` in our
headers, which seems wrong (and causes the DSL to break unless you add
casts). I've corrected the headers to use `half eta`.
