 935  * he surface that is attached is AddRef-ed.
 936  *
 937  * Tests with complex surfaces suggest that the surface attachments form a
 938  * tree, but no method to test this has been found yet.
 939  *
 940  * The attachment list consists of a first surface (first_attached) and
 941  * for each surface a pointer to the next attached surface (next_attached).
 942  * For the first surface, and a surface that has no attachments
 943  * first_attached points to the surface itself. A surface that has
 944  * no successors in the chain has next_attached set to NULL.
 945  *
 946  * Newly attached surfaces are attached right after the root surface.
 947  * If a surface is attached to a complex surface compound, it's attached to
 948  * the surface that the app requested, not the complex root. See
 949  * GetAttachedSurface for a description how surfaces are found.
 950  *
 951  * This is how the current implementation works, and it was coded by looking
 952  * at the needs of the applications.
 953  *
 954  * So far only Z-Buffer attachments are tested, and they are activated in
 955  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
 956  * Back buffers should work in 2D mode, but they are not tested(They can be
 957  * attached in older iface versions). Rendering to the front buffer and
 958  * switching between that and double buffering is not yet implemented in
 959  * WineD3D, so for 3D it might have unexpected results.
 960  *
 961  * ddraw_surface_attach_surface is the real thing,
