Bit-exact Nearest Neighbor Resizing * bit exact resizeNN * change the value of method enum * add bitexact-nn to ResizeExactTest * test to compare with non-exact version * add perf for bit-exact resizenn * use cvFloor-equivalent * 1/3 scaling is not stable for floating calculation * stricter test * bugfix: broken data in case of 6 or 12bytes elements * bugfix: broken data in default pix_size * stricter threshold * use raw() for floor * use double instead of int * follow code reviews * fewer cases in perf test * center pixel convention
