	Returns the square root of the vector.

Vec4	Abs () const
	Returns a vector containing the absolute values of all components.

Vec4	SortAsc () const
	Returns a vector with components sorted in ascending order.

Vec4	SortDesc () const
	Returns a vector with components sorted in descending order.

Limit methods
void	Clamp (T minLimit, T maxLimit)
