functions can not consume a swizzled vector directly

[fknfilewalker]

It would be nice to allow some implicite conversions for _swizzle types so that functions like normalize can consume them directly.

The following does not work:

glm::vec4 vector = { 1.0f, 2.0f, 3.0f, 4.0f };
glm::normalize(vector.xxx);

This works:

glm::vec4 vector = { 1.0f, 2.0f, 3.0f, 4.0f };
glm::vec3 vector2 = vector.xxx;
glm::normalize(vector2);

one way would be to add additional functions like

template<glm::length_t L, typename T, glm::qualifier Q, int E0, int E1, int E2, int E3>
glm::vec<L, T, Q> normalize(glm::detail::_swizzle<L, T, Q, E0, E1, E2, E3> const& x)
{
    return glm::detail::compute_normalize<L, T, Q, glm::detail::is_aligned<Q>::value>::call(x);
}
