 472  * What happens here is basically this:
 473  * When a surface is destroyed, its WineD3DSurface is released,
 474  * and the refcount of the DirectDraw interface is reduced by 1. If it has
 475  * complex surfaces attached to it, then these surfaces are destroyed too,
 476  * regardless of their refcount. If any surface being destroyed has another
 477  * surface attached to it (with a "soft" attachment, not complex), then
 478  * this surface is detached with DeleteAttachedSurface.
 479  *
 480  * When the surface is a texture, the WineD3DTexture is released.
 481  * If the surface is the Direct3D render target, then the D3D
 482  * capabilities of the WineD3DDevice are uninitialized, which causes the
 483  * swapchain to be released.

1233  * IDirectDrawSurface7::AddAttachedSurface
1234  *
1235  * Attaches a surface to another surface. How the surface attachments work
1236  * is not totally understood yet, and this method is prone to problems.
1237  * he surface that is attached is AddRef-ed.
1238  *
1239  * Tests with complex surfaces suggest that the surface attachments form a
1240  * tree, but no method to test this has been found yet.
1241  *
1242  * The attachment list consists of a first surface (first_attached) and
1243  * for each surface a pointer to the next attached surface (next_attached).
1244  * For the first surface, and a surface that has no attachments
1245  * first_attached points to the surface itself. A surface that has
1246  * no successors in the chain has next_attached set to NULL.
1247  *
1248  * Newly attached surfaces are attached right after the root surface.
1249  * If a surface is attached to a complex surface compound, it's attached to
1250  * the surface that the app requested, not the complex root. See
1251  * GetAttachedSurface for a description how surfaces are found.
1252  *
1253  * This is how the current implementation works, and it was coded by looking
1254  * at the needs of the applications.
1255  *
1256  * So far only Z-Buffer attachments are tested, and they are activated in
1257  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1258  * Back buffers should work in 2D mode, but they are not tested(They can be
1259  * attached in older iface versions). Rendering to the front buffer and
1260  * switching between that and double buffering is not yet implemented in
1261  * WineD3D, so for 3D it might have unexpected results.
1262  *
1263  * ddraw_surface_attach_surface is the real thing,
1264  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1265  * performs additional checks. Version 7 of this interface is much more restrictive
1266  * than its predecessors.
