359 The output has been subject to swaps of the form
360 0 1 -> 3 1 but the odd and even bits have been put into
361 2 3 2 0
362 different words. The main trick is to remember that
363 t=((l>>size)^r)&(mask);
364 r^=t;
365 l^=(t<<size);
366 can be used to swap and move bits between words.

378 Thanks for hints from Richard Outerbridge - he told me IP&FP
379 could be done in 15 xor, 10 shifts and 5 ands.
380 When I finally started to think of the problem in 2D
381 I first got ~42 operations without xors. When I remembered
382 how to use xors :-) I got it to its final state.
