 885  * is not totally understood yet, and this method is prone to problems.
 886  * he surface that is attached is AddRef-ed.
 887  *
 888  * Tests with complex surfaces suggest that the surface attachments form a
 889  * tree, but no method to test this has been found yet.
 890  *
 891  * The attachment list consists of a first surface (first_attached) and
 892  * for each surface a pointer to the next attached surface (next_attached).
 893  * For the first surface, and a surface that has no attachments
 894  * first_attached points to the surface itself. A surface that has
 895  * no successors in the chain has next_attached set to NULL.
 896  *
 897  * Newly attached surfaces are attached right after the root surface.
 898  * If a surface is attached to a complex surface compound, it's attached to
 899  * the surface that the app requested, not the complex root. See
 900  * GetAttachedSurface for a description how surfaces are found.
 901  *
 902  * This is how the current implementation works, and it was coded by looking
 903  * at the needs of the applications.
 904  *
 905  * So far only Z-Buffer attachments are tested, and they are activated in
 906  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
 907  * Back buffers should work in 2D mode, but they are not tested(They can be
 908  * attached in older iface versions). Rendering to the front buffer and
 909  * switching between that and double buffering is not yet implemented in
 910  * WineD3D, so for 3D it might have unexpected results.
 911  *
 912  * ddraw_surface_attach_surface is the real thing,
