// Desc: In this tutorial, we are rendering some vertices. This introduces the
// concept of the vertex buffer, a Direct3D object used to store
// vertices. Vertices can be defined any way we want by defining a
// custom structure and a custom FVF (flexible vertex format). In this
// tutorial, we are using vertices that are transformed (meaning they
// are already in 2D window coordinates) and lit (meaning we are not
// using Direct3D lighting, but are supplying our own colors).
