1806  * IDirectDrawSurface7::AddAttachedSurface
1807  *
1808  * Attaches a surface to another surface. How the surface attachments work
1809  * is not totally understood yet, and this method is prone to problems.
1810  * The surface that is attached is AddRef-ed.
1811  *
1812  * Tests with complex surfaces suggest that the surface attachments form a
1813  * tree, but no method to test this has been found yet.
1814  *
1815  * The attachment list consists of a first surface (first_attached) and
1816  * for each surface a pointer to the next attached surface (next_attached).
1817  * For the first surface, and a surface that has no attachments
1818  * first_attached points to the surface itself. A surface that has
1819  * no successors in the chain has next_attached set to NULL.
1820  *
1821  * Newly attached surfaces are attached right after the root surface.
1822  * If a surface is attached to a complex surface compound, it's attached to
1823  * the surface that the app requested, not the complex root. See
1824  * GetAttachedSurface for a description how surfaces are found.
1825  *
1826  * This is how the current implementation works, and it was coded by looking
1827  * at the needs of the applications.
1828  *
1829  * So far only Z-Buffer attachments are tested, and they are activated in
1830  * WineD3D. Mipmaps could be tricky to activate in WineD3D.
1831  * Back buffers should work in 2D mode, but they are not tested(They can be
1832  * attached in older iface versions). Rendering to the front buffer and
1833  * switching between that and double buffering is not yet implemented in
1834  * WineD3D, so for 3D it might have unexpected results.
1835  *
1836  * ddraw_surface_attach_surface is the real thing,
1837  * ddraw_surface7_AddAttachedSurface is a wrapper around it that
1838  * performs additional checks. Version 7 of this interface is much more restrictive
1839  * than its predecessors.
1840  *
1841  * Params:
1842  *  Attach: Surface to attach to iface
1843  *
1844  * Returns:
1845  *  DD_OK on success
1846  *  DDERR_CANNOTATTACHSURFACE if the surface can't be attached for some reason
