 946  *
 947  * The attachment list consists of a first surface (first_attached) and
 948  * for each surface a pointer to the next attached surface (next_attached).
 949  * For the first surface, and a surface that has no attachments
 950  * first_attached points to the surface itself. A surface that has

 953  * Newly attached surfaces are attached right after the root surface.
 954  * If a surface is attached to a complex surface compound, it's attached to
