 572  * Destroying the surface is a bit tricky. For the connection between

 574  * It has a nice graph explaining the connection.
 575  *
 576  * What happens here is basically this:
 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.
 588  *
 589  * When a complex sublevel falls to ref zero, then this is ignored.

1616  * IDirectDrawSurface7::AddAttachedSurface
1617  *
1618  * Attaches a surface to another surface. How the surface attachments work
1619  * is not totally understood yet, and this method is prone to problems.
1620  * The surface that is attached is AddRef-ed.
1621  *
1622  * Tests with complex surfaces suggest that the surface attachments form a
1623  * tree, but no method to test this has been found yet.
1624  *
1625  * The attachment list consists of a first surface (first_attached) and
1626  * for each surface a pointer to the next attached surface (next_attached).
1627  * For the first surface, and a surface that has no attachments
1628  * first_attached points to the surface itself. A surface that has
1629  * no successors in the chain has next_attached set to NULL.
1630  *
1631  * Newly attached surfaces are attached right after the root surface.
1632  * If a surface is attached to a complex surface compound, it's attached to
1633  * the surface that the app requested, not the complex root. See
1634  * GetAttachedSurface for a description how surfaces are found.
1635  *
1636  * This is how the current implementation works, and it was coded by looking
1637  * at the needs of the applications.
1638  *
1639  * So far only Z-Buffer attachments are tested, and they are activated in
1640  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1641  * Back buffers should work in 2D mode, but they are not tested(They can be
1642  * attached in older iface versions). Rendering to the front buffer and
1643  * switching between that and double buffering is not yet implemented in
1644  * WineD3D, so for 3D it might have unexpected results.
1645  *
1646  * ddraw_surface_attach_surface is the real thing,
1647  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1648  * performs additional checks. Version 7 of this interface is much more restrictive
1649  * than its predecessors.
