' Applications use the methods of the IDirect3DIndexBuffer9 interface to manipulate an index
' buffer resource.
' The IDirect3DIndexBuffer9 interface is obtained by calling the IDirect3DDevice9::CreateIndexBuffer method.
' This interface inherits additional functionality from the IDirect3DResource9 interface.
