 934  * he surface that is attached is AddRef-ed.
 935  *
 936  * Tests with complex surfaces suggest that the surface attachments form a
 937  * tree, but no method to test this has been found yet.
 938  *
 939  * The attachment list consists of a first surface (first_attached) and
 940  * for each surface a pointer to the next attached surface (next_attached).
 941  * For the first surface, and a surface that has no attachments
 942  * first_attached points to the surface itself. A surface that has
 943  * no successors in the chain has next_attached set to NULL.
 944  *
 945  * Newly attached surfaces are attached right after the root surface.
 946  * If a surface is attached to a complex surface compound, it's attached to
 947  * the surface that the app requested, not the complex root. See
 948  * GetAttachedSurface for a description how surfaces are found.
 949  *
 950  * This is how the current implementation works, and it was coded by looking
 951  * at the needs of the applications.
 952  *
 953  * So far only Z-Buffer attachments are tested, and they are activated in
 954  * WineD3D. Mipmaps could be tricky to activate in WineD3D.

 957  * switching between that and double buffering is not yet implemented in
 958  * WineD3D, so for 3D it might have unexpected results.
 959  *
 960  * ddraw_surface_attach_surface is the real thing,
