Subject: Thank you kindly, Godfrey, for a patch that: The vector parameter to
 llSetPos() specifies an absolute position for an unlinked prim or the root
 prim of a linkset; however, when the function is used by a child prim, the
 vector specifies a relative offset from the root prim. The changed introduced
 in llSetPos() treats this value as an absolute position in all cases, which
 has the unintended effect of mangling the position of child prims.
