Concept definition

template<typename Xf, typename T, index_t N>
concept Transform = requires (Xf xf, Vec<T,N> p) {
    // transforms can be applied to points
    { xf * p } -> std::convertible_to<Vec<T,N>>;
    // inverse transforms can be applied to points
    { p / xf } -> std::convertible_to<Vec<T,N>>;
    // transforms can be composed
    { xf * xf } -> std::convertible_to<Xf>;
    // transforms have inverses
    { xf.inverse() } -> std::convertible_to<Xf>;
    // transforms can operate on directions
    { xf.apply_direction(p) } -> std::convertible_to<Vec<T,N>>;
    // inverse transforms can operate on directions
    { xf.apply_inverse_direction(p) } -> std::convertible_to<Vec<T,N>>;
    // transforms can in-place compose
    { xf *= xf } -> std::convertible_to<Xf>;
    // transforms can in-place apply inverse
    { xf /= xf } -> std::convertible_to<Xf>;
}
