 850  * IDirectDrawSurface7::AddAttachedSurface
 851  *
 852  * Attaches a surface to another surface. How the surface attachments work
 853  * is not totally understood yet, and this method is prone to problems.
 854  * he surface that is attached is AddRef-ed.
 855  *
 856  * Tests with complex surfaces suggest that the surface attachments form a
 857  * tree, but no method to test this has been found yet.
 858  *
 859  * The attachment list consists of a first surface (first_attached) and
 860  * for each surface a pointer to the next attached surface (next_attached).
 861  * For the first surface, and a surface that has no attachments
 862  * first_attached points to the surface itself. A surface that has
 863  * no successors in the chain has next_attached set to NULL.
 864  *
 865  * Newly attached surfaces are attached right after the root surface.
 866  * If a surface is attached to a complex surface compound, it's attached to
 867  * the surface that the app requested, not the complex root. See
 868  * GetAttachedSurface for a description how surfaces are found.
 869  *
 870  * This is how the current implementation works, and it was coded by looking
 871  * at the needs of the applications.
 872  *
 873  * So far only Z-Buffer attachments are tested, and they are activated in
 874  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
 875  * Back buffers should work in 2D mode, but they are not tested(They can be
 876  * attached in older iface versions). Rendering to the front buffer and
 877  * switching between that and double buffering is not yet implemented in
 878  * WineD3D, so for 3D it might have unexpected results.
 879  *
 880  * IDirectDrawSurfaceImpl_AddAttachedSurface is the real thing,
 881  * IDirectDrawSurface7Impl_AddAttachedSurface is a wrapper around it that
 882  * performs additional checks. Version 7 of this interface is much more restrictive
