Access glm::vec3 component by argument?

[PrestoChung]

Is there a way to access one component of a glm vector by argument?

Example:

bool greaterThan( const glm::vec3& lhs, const glm::vec3& rhs, const Axis axis )
{
    return lhs.component( axis ) > rhs.component( axis );
}

Yes. You use [] with an integer. As in `lhs[axis]`, where `axis` is an integer.
