1749  * IDirectDrawSurface7::AddAttachedSurface
1750  *
1751  * Attaches a surface to another surface. How the surface attachments work
1752  * is not totally understood yet, and this method is prone to problems.
1753  * The surface that is attached is AddRef-ed.
1754  *
1755  * Tests with complex surfaces suggest that the surface attachments form a
1756  * tree, but no method to test this has been found yet.
1757  *
1758  * The attachment list consists of a first surface (first_attached) and
1759  * for each surface a pointer to the next attached surface (next_attached).
1760  * For the first surface, and a surface that has no attachments
1761  * first_attached points to the surface itself. A surface that has
1762  * no successors in the chain has next_attached set to NULL.
1763  *
1764  * Newly attached surfaces are attached right after the root surface.
1765  * If a surface is attached to a complex surface compound, it's attached to
1766  * the surface that the app requested, not the complex root. See
1767  * GetAttachedSurface for a description how surfaces are found.
1768  *
1769  * This is how the current implementation works, and it was coded by looking
1770  * at the needs of the applications.
1771  *
1772  * So far only Z-Buffer attachments are tested, and they are activated in
1773  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1774  * Back buffers should work in 2D mode, but they are not tested(They can be
1775  * attached in older iface versions). Rendering to the front buffer and
1776  * switching between that and double buffering is not yet implemented in
1777  * WineD3D, so for 3D it might have unexpected results.
1778  *
1779  * ddraw_surface_attach_surface is the real thing,
1780  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1781  * performs additional checks. Version 7 of this interface is much more restrictive
1782  * than its predecessors.
