| 382 can be used to swap and move bits between words. | |
| 383 | |
| 384 So l = 0 1 2 3 r = 16 17 18 19 | |
| 385 4 5 6 7 20 21 22 23 | |
| 386 8 9 10 11 24 25 26 27 | |
| 387 12 13 14 15 28 29 30 31 | |
| 388 becomes (for size == 2 and mask == 0x3333) | |
| 389 t = 2^16 3^17 -- -- l = 0 1 16 17 r = 2 3 18 19 | |
| 390 6^20 7^21 -- -- 4 5 20 21 6 7 22 23 | |
| 391 10^24 11^25 -- -- 8 9 24 25 10 11 24 25 | |
| 392 14^28 15^29 -- -- 12 13 28 29 14 15 28 29 | |

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