Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Postponse free of coords, shapes, and paints when the rdman is dirty. - Life-cycle of shapes and paints are managed by rdman. - Add redraw_man_t::free_objs to collect objects their freeing are postonsed. Know Issue: - Bullet of tank are not removed from screen when it is go out the range of the map.
