 647  * surface attached to it (with a "soft" attachment, not complex), then
 648  * this surface is detached with DeleteAttachedSurface.
 649  *
 650  * When the surface is a texture, the WineD3DTexture is released.
 651  * If the surface is the Direct3D render target, then the D3D
 652  * capabilities of the WineD3DDevice are uninitialized, which causes the

1926  * The surface that is attached is AddRef-ed.
1927  *
1928  * Tests with complex surfaces suggest that the surface attachments form a
1929  * tree, but no method to test this has been found yet.
1930  *
1931  * The attachment list consists of a first surface (first_attached) and
1932  * for each surface a pointer to the next attached surface (next_attached).
1933  * For the first surface, and a surface that has no attachments
1934  * first_attached points to the surface itself. A surface that has
1935  * no successors in the chain has next_attached set to NULL.
1936  *
1937  * Newly attached surfaces are attached right after the root surface.
1938  * If a surface is attached to a complex surface compound, it's attached to
1939  * the surface that the app requested, not the complex root. See
1940  * GetAttachedSurface for a description how surfaces are found.
1941  *
1942  * This is how the current implementation works, and it was coded by looking
1943  * at the needs of the applications.
1944  *
1945  * So far only Z-Buffer attachments are tested, and they are activated in
1946  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1947  * Back buffers should work in 2D mode, but they are not tested(They can be
1948  * attached in older iface versions). Rendering to the front buffer and
1949  * switching between that and double buffering is not yet implemented in
1950  * WineD3D, so for 3D it might have unexpected results.
1951  *
1952  * ddraw_surface_attach_surface is the real thing,
1953  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1954  * performs additional checks. Version 7 of this interface is much more restrictive
1955  * than its predecessors.
