 540  *
 541  * What happens here is basically this:
 542  * When a surface is destroyed, its WineD3DSurface is released,
 543  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 544  * complex surfaces attached to it, then these surfaces are destroyed too,
 545  * regardless of their refcount. If any surface being destroyed has another
 546  * surface attached to it (with a "soft" attachment, not complex), then
 547  * this surface is detached with DeleteAttachedSurface.
 548  *
 549  * When the surface is a texture, the WineD3DTexture is released.
 550  * If the surface is the Direct3D render target, then the D3D
 551  * capabilities of the WineD3DDevice are uninitialized, which causes the
 552  * swapchain to be released.
 553  *
 554  * When a complex sublevel falls to ref zero, then this is ignored.

1406  * The surface that is attached is AddRef-ed.
1407  *
1408  * Tests with complex surfaces suggest that the surface attachments form a
1409  * tree, but no method to test this has been found yet.
1410  *
1411  * The attachment list consists of a first surface (first_attached) and
1412  * for each surface a pointer to the next attached surface (next_attached).
1413  * For the first surface, and a surface that has no attachments
1414  * first_attached points to the surface itself. A surface that has
1415  * no successors in the chain has next_attached set to NULL.
1416  *
1417  * Newly attached surfaces are attached right after the root surface.
1418  * If a surface is attached to a complex surface compound, it's attached to
1419  * the surface that the app requested, not the complex root. See
1420  * GetAttachedSurface for a description how surfaces are found.
1421  *
1422  * This is how the current implementation works, and it was coded by looking
1423  * at the needs of the applications.
1424  *
1425  * So far only Z-Buffer attachments are tested, and they are activated in
1426  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1427  * Back buffers should work in 2D mode, but they are not tested(They can be
1428  * attached in older iface versions). Rendering to the front buffer and
1429  * switching between that and double buffering is not yet implemented in
1430  * WineD3D, so for 3D it might have unexpected results.
1431  *
1432  * ddraw_surface_attach_surface is the real thing,
