Expand description

Shuffles two vectors by const indices.

`T` must be a vector.

`U` must be a const vector of `u32`s. This means it must either refer to a named const or be given as an inline const expression (`const { ... }`).

`V` must be a vector with the same element type as `T` and the same length as `U`.

Returns a new vector such that element `i` is selected from `xy[idx[i]]`, where `xy` is the concatenation of `x` and `y`. It is a compile-time error if `idx[i]` is out-of-bounds of `xy`.
