Detailed Description

This is a special class object that holds all the information returned by a particular GSG to indicate the vertex data array's internal context identifier.

This allows the GSG to cache the vertex data array in whatever way makes sense. For instance, DirectX can allocate a vertex buffer for the array. OpenGL can create a buffer object.
