 847  * IDirectDrawSurface7::AddAttachedSurface
 848  *
 849  * Attaches a surface to another surface. How the surface attachments work
 850  * is not totally understood yet, and this method is prone to problems.
 851  * he surface that is attached is AddRef-ed.
 852  *
 853  * Tests with complex surfaces suggest that the surface attachments form a
 854  * tree, but no method to test this has been found yet.
 855  *
 856  * The attachment list consists of a first surface (first_attached) and
 857  * for each surface a pointer to the next attached surface (next_attached).
 858  * For the first surface, and a surface that has no attachments
 859  * first_attached points to the surface itself. A surface that has
 860  * no successors in the chain has next_attached set to NULL.
 861  *
 862  * Newly attached surfaces are attached right after the root surface.
 863  * If a surface is attached to a complex surface compound, it's attached to
 864  * the surface that the app requested, not the complex root. See
 865  * GetAttachedSurface for a description how surfaces are found.
 866  *
 867  * This is how the current implementation works, and it was coded by looking
 868  * at the needs of the applications.
 869  *
 870  * So far only Z-Buffer attachments are tested, and they are activated in
 871  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
 872  * Back buffers should work in 2D mode, but they are not tested(They can be
 873  * attached in older iface versions). Rendering to the front buffer and
 874  * switching between that and double buffering is not yet implemented in
 875  * WineD3D, so for 3D it might have unexpected results.
 876  *
 877  * IDirectDrawSurfaceImpl_AddAttachedSurface is the real thing,
 878  * IDirectDrawSurface7Impl_AddAttachedSurface is a wrapper around it that
 879  * performs additional checks. Version 7 of this interface is much more restrictive
