nCine::Primitives::Vector4 class

Four-component vector.

Stores four values X, Y, Z and W. Provides component-wise arithmetic, scalar arithmetic, length and normalization, dot product and linear interpolation. Can be constructed from a Vector2 or Vector3 plus the remaining components and converted back with ToVector2() and ToVector3().
