 577  * When a surface is destroyed, its WineD3DSurface is released,
 578  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 579  * complex surfaces attached to it, then these surfaces are destroyed too,
 580  * regardless of their refcount. If any surface being destroyed has another
 581  * surface attached to it (with a "soft" attachment, not complex), then
 582  * this surface is detached with DeleteAttachedSurface.
 583  *
 584  * When the surface is a texture, the WineD3DTexture is released.
 585  * If the surface is the Direct3D render target, then the D3D
 586  * capabilities of the WineD3DDevice are uninitialized, which causes the
 587  * swapchain to be released.

1729  * IDirectDrawSurface7::AddAttachedSurface
1730  *
1731  * Attaches a surface to another surface. How the surface attachments work
1732  * is not totally understood yet, and this method is prone to problems.
1733  * The surface that is attached is AddRef-ed.
1734  *
1735  * Tests with complex surfaces suggest that the surface attachments form a
1736  * tree, but no method to test this has been found yet.
1737  *
1738  * The attachment list consists of a first surface (first_attached) and
1739  * for each surface a pointer to the next attached surface (next_attached).
1740  * For the first surface, and a surface that has no attachments
1741  * first_attached points to the surface itself. A surface that has
1742  * no successors in the chain has next_attached set to NULL.
1743  *
1744  * Newly attached surfaces are attached right after the root surface.
1745  * If a surface is attached to a complex surface compound, it's attached to
1746  * the surface that the app requested, not the complex root. See
1747  * GetAttachedSurface for a description how surfaces are found.
1748  *
1749  * This is how the current implementation works, and it was coded by looking
1750  * at the needs of the applications.
1751  *
1752  * So far only Z-Buffer attachments are tested, and they are activated in
1753  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1754  * Back buffers should work in 2D mode, but they are not tested(They can be
1755  * attached in older iface versions). Rendering to the front buffer and
1756  * switching between that and double buffering is not yet implemented in
1757  * WineD3D, so for 3D it might have unexpected results.
1758  *
1759  * ddraw_surface_attach_surface is the real thing,
1760  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1761  * performs additional checks. Version 7 of this interface is much more restrictive
1762  * than its predecessors.
