Remarks
This base class cannot be used directly. Instead, a steam that is specific for each type of vertex must be used. The process of putting vertex data into a buffer involves using a stream-buffer pair as follows:
  1. Map the vertex buffer.
  2. Get a stream of the appropriate type from the buffer.
  3. Add vertices of the same type to the stream. They will be written into the buffer that was used to create the stream.
  4. Unmap the buffer.
As an alternative to using streams, it is possible to write data into a buffer using a handle to its mapped memory.
