// In quite a lot of subfiles often the sequence x, y, z, u, v, r, g, b, a 
// occurs. It looks like this is a vertex with [x, y, z] as coordinates,
// [u, v] as coordinates for u, v mapping and [r, g, b, a] as color value. In 
// order to make it easier to work with this, we've put them inside a separate 
// class.
