Fix bug of tanks do not show at right places. Since we avoid to dirty a subtree if root of a subtree have been dirty or hidden, it make children that was added into coord tree after a coord be dirty do not be marked with COF_DIRTY flag. To fix it, when a new coord is created, the parent is checked and mark new coord with COF_DIRTY flag if the parent is dirty. It forces new coords to be cleaned and transformed to right places.
