Vadim Pisarevsky	5ddd25313f	Add Grana's connected components algorithm for 8-way connectivity. (#6823 ) * Add Grana's connected components algorithm for 8-way connectivity. That algorithm is faster than Wu's one (currently implemented in opencv). For more details see https://github.com/prittt/YACCLAB. * New functions signature and distance transform compatibility * Add tests to imgproc/test/test_connectedcomponents.cpp * Change of test_connectedcomponents.cpp for c++98 support	8 years ago
