 565  * Destroying the surface is a bit tricky. For the connection between
 566  * WineD3DSurfaces and DirectDrawSurfaces see IDirectDraw7::CreateSurface
 567  * It has a nice graph explaining the connection.
 568  *
 569  * What happens here is basically this:
 570  * When a surface is destroyed, its WineD3DSurface is released,
 571  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 572  * complex surfaces attached to it, then these surfaces are destroyed too,
 573  * regardless of their refcount. If any surface being destroyed has another
 574  * surface attached to it (with a "soft" attachment, not complex), then
 575  * this surface is detached with DeleteAttachedSurface.
 576  *
 577  * When the surface is a texture, the WineD3DTexture is released.
 578  * If the surface is the Direct3D render target, then the D3D
 579  * capabilities of the WineD3DDevice are uninitialized, which causes the
 580  * swapchain to be released.
 581  *
 582  * When a complex sublevel falls to ref zero, then this is ignored.

1725  * IDirectDrawSurface7::AddAttachedSurface
1726  *
1727  * Attaches a surface to another surface. How the surface attachments work
1728  * is not totally understood yet, and this method is prone to problems.
1729  * The surface that is attached is AddRef-ed.
1730  *
1731  * Tests with complex surfaces suggest that the surface attachments form a
1732  * tree, but no method to test this has been found yet.
1733  *
1734  * The attachment list consists of a first surface (first_attached) and
1735  * for each surface a pointer to the next attached surface (next_attached).
1736  * For the first surface, and a surface that has no attachments
1737  * first_attached points to the surface itself. A surface that has
1738  * no successors in the chain has next_attached set to NULL.
1739  *
1740  * Newly attached surfaces are attached right after the root surface.
1741  * If a surface is attached to a complex surface compound, it's attached to
1742  * the surface that the app requested, not the complex root. See
1743  * GetAttachedSurface for a description how surfaces are found.
1744  *
1745  * This is how the current implementation works, and it was coded by looking
1746  * at the needs of the applications.
1747  *
1748  * So far only Z-Buffer attachments are tested, and they are activated in
1749  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1750  * Back buffers should work in 2D mode, but they are not tested(They can be
1751  * attached in older iface versions). Rendering to the front buffer and
1752  * switching between that and double buffering is not yet implemented in
1753  * WineD3D, so for 3D it might have unexpected results.
1754  *
1755  * ddraw_surface_attach_surface is the real thing,
1756  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1757  * performs additional checks. Version 7 of this interface is much more restrictive
1758  * than its predecessors.
