 568  * Destroying the surface is a bit tricky. For the connection between
 569  * WineD3DSurfaces and DirectDrawSurfaces see IDirectDraw7::CreateSurface
 570  * It has a nice graph explaining the connection.
 571  *
 572  * What happens here is basically this:
 573  * When a surface is destroyed, its WineD3DSurface is released,
 574  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 575  * complex surfaces attached to it, then these surfaces are destroyed too,
 576  * regardless of their refcount. If any surface being destroyed has another
 577  * surface attached to it (with a "soft" attachment, not complex), then
 578  * this surface is detached with DeleteAttachedSurface.
 579  *
 580  * When the surface is a texture, the WineD3DTexture is released.
 581  * If the surface is the Direct3D render target, then the D3D
 582  * capabilities of the WineD3DDevice are uninitialized, which causes the
 583  * swapchain to be released.
 584  *
 585  * When a complex sublevel falls to ref zero, then this is ignored.

1624  * Newly attached surfaces are attached right after the root surface.
1625  * If a surface is attached to a complex surface compound, it's attached to
1626  * the surface that the app requested, not the complex root. See
1627  * GetAttachedSurface for a description how surfaces are found.
1628  *
1629  * This is how the current implementation works, and it was coded by looking
1630  * at the needs of the applications.
1631  *
1632  * So far only Z-Buffer attachments are tested, and they are activated in
1633  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1634  * Back buffers should work in 2D mode, but they are not tested(They can be
1635  * attached in older iface versions). Rendering to the front buffer and
1636  * switching between that and double buffering is not yet implemented in
1637  * WineD3D, so for 3D it might have unexpected results.
1638  *
1639  * ddraw_surface_attach_surface is the real thing,
1640  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1641  * performs additional checks. Version 7 of this interface is much more restrictive
1642  * than its predecessors.
