annotate src/redraw_man.c @ 138:9f4fc9ecfd1f

Make shapes and coords drawed in post-order of tree. 1. Add opacity for each coord. 2. Trival and draw tree of shapes and coords in post-order. 3. Coords have a before_pmem member variable to note it's order been draw. It is relative to it's siblings and member shapes of parent coord.
