* IDirectDrawSurface7::AddAttachedSurface
*
* Attaches a surface to another surface. How the surface attachments work
* is not totally understood yet, and this method is prone to problems.
* he surface that is attached is AddRef-ed.
*
* Tests with complex surfaces suggest that the surface attachments form a
* tree, but no method to test this has been found yet.
*
* The attachment list consists of a first surface (first_attached) and
* for each surface a pointer to the next attached surface (next_attached).
* For the first surface, and a surface that has no attachments
* first_attached points to the surface itself. A surface that has
* no successors in the chain has next_attached set to NULL.
*
* Newly attached surfaces are attached right after the root surface.
* If a surface is attached to a complex surface compound, it's attached to
* the surface that the app requested, not the complex root. See
* GetAttachedSurface for a description how surfaces are found.
*
* This is how the current implementation works, and it was coded by looking
* at the needs of the applications.
*
* So far only Z-Buffer attachments are tested, and they are activated in
* WineD3D. Mipmaps could be tricky to activate in WineD3D.
* Back buffers should work in 2D mode, but they are not tested(They can be
* attached in older iface versions). Rendering to the front buffer and
* switching between that and double buffering is not yet implemented in
* WineD3D, so for 3D it might have unexpected results.
*
* IDirectDrawSurfaceImpl_AddAttachedSurface is the real thing,
* IDirectDrawSurface7Impl_AddAttachedSurface is a wrapper around it that
* performs additional checks. Version 7 of this interface is much more restrictive
* than its predecessors.
*
* Params:
* Attach: Surface to attach to iface
*
* Returns:
* DD_OK on success
