 499  *
 500  * What happens here is basically this:
 501  * When a surface is destroyed, its WineD3DSurface is released,
 502  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 503  * complex surfaces attached to it, then these surfaces are destroyed too,
 504  * regardless of their refcount. If any surface being destroyed has another
 505  * surface attached to it (with a "soft" attachment, not complex), then
 506  * this surface is detached with DeleteAttachedSurface.
 507  *
 508  * When the surface is a texture, the WineD3DTexture is released.
 509  * If the surface is the Direct3D render target, then the D3D
 510  * capabilities of the WineD3DDevice are uninitialized, which causes the
 511  * swapchain to be released.
 512  *
 513  * When a complex sublevel falls to ref zero, then this is ignored.

1332  * Attaches a surface to another surface. How the surface attachments work
1333  * is not totally understood yet, and this method is prone to problems.
1334  * he surface that is attached is AddRef-ed.
1335  *
1336  * Tests with complex surfaces suggest that the surface attachments form a
1337  * tree, but no method to test this has been found yet.
1338  *
1339  * The attachment list consists of a first surface (first_attached) and
1340  * for each surface a pointer to the next attached surface (next_attached).
1341  * For the first surface, and a surface that has no attachments
1342  * first_attached points to the surface itself. A surface that has
1343  * no successors in the chain has next_attached set to NULL.
1344  *
1345  * Newly attached surfaces are attached right after the root surface.
1346  * If a surface is attached to a complex surface compound, it's attached to
1347  * the surface that the app requested, not the complex root. See
1348  * GetAttachedSurface for a description how surfaces are found.
1349  *
1350  * This is how the current implementation works, and it was coded by looking
1351  * at the needs of the applications.
1352  *
1353  * So far only Z-Buffer attachments are tested, and they are activated in
1354  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1355  * Back buffers should work in 2D mode, but they are not tested(They can be
1356  * attached in older iface versions). Rendering to the front buffer and
1357  * switching between that and double buffering is not yet implemented in
1358  * WineD3D, so for 3D it might have unexpected results.
1359  *
1360  * ddraw_surface_attach_surface is the real thing,
1361  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1362  * performs additional checks. Version 7 of this interface is much more restrictive
