Anchor this node by creating an anchored node at the given position, then parenting this
node with the anchor and setting this node to the origin. Note that this node's current
position is ignored. If anchoring fails, then the node is simply set to the position, and
we try again later.

@param position The position at which to anchor the node.
@return True if anchoring succeeded.
