comparison include/mb_types.h @ 232:527894c2ad39

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add functions for collision test. - mb_obj_pos_is_in() test if two coords and their descendants are overlaid. - mb_objs_is_overlay() test if a point is covered by another mb_obj_t.
