annotate src/timertool.c @ 1399:9cebe429508c
Override the clone_from_subtree to setup the parent and children for the coord object. However, the current children is incorrect since we can not copy it from the origin tree. Instead, we need to get coord_t from the cloned group and then modify all coord objects to include correct parent, children, add_shape and clone_from_subtree.
