375 375 The output has been subject to swaps of the form
376 376 0 1 -> 3 1 but the odd and even bits have been put into
377 377 2 3 2 0
378 378 different words. The main trick is to remember that
379 379 t=((l>>size)^r)&(mask);
380 380 r^=t;
381 381 l^=(t<<size);
382 382 can be used to swap and move bits between words.
383 383
384 384 So l = 0 1 2 3 r = 16 17 18 19
385 385 4 5 6 7 20 21 22 23

387 387 12 13 14 15 28 29 30 31
388 388 becomes (for size == 2 and mask == 0x3333)
389 389 t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19
390 390 6^20 7^21 -- -- 4 5 20 21 6 7 22 23
391 391 10^24 11^25 -- -- 8 9 24 25 10 11 24 25
392 392 14^28 15^29 -- -- 12 13 28 29 14 15 28 29

394 394 Thanks for hints from Richard Outerbridge - he told me IP&FP
395 395 could be done in 15 xor, 10 shifts and 5 ands.
396 396 When I finally started to think of the problem in 2D
397 397 I first got ~42 operations without xors. When I remembered
398 398 how to use xors :-) I got it to its final state.
