Browse Source 
(methods 5 and 6 are still untouched).

Methods #0 and #1 got much faster
Method #2 gets vastly improved in quality
Method #3 is noticeably faster for little lower quality
Method #4 (default) is 10-20% faster for comparable quality

+ update the internal doc about the methods' tools.

Example of speed difference:
