26     You will not be able to compile this file correctly without gcc, because
27     it is necessary to pack the "wavefront_alias" structure to a size
28     of 22 bytes, corresponding to 16-bit alignment (as would have been
29     the case on the original platform, MS-DOS). If this is not done,
30     then WavePatch-format files cannot be read/written correctly.
31     The method used to do this here ("__attribute__((packed)") is
32     completely compiler dependent.
33     
34     All other wavefront_* types end up aligned to 32 bit values and
35     still have the same (correct) size.

397  Because most/all of the sample data we pass in via pointers has
398  never been copied (just mmap-ed into user space straight from the
399  disk), it would be nice to allow handling of multi-channel sample
400  data without forcing user-level extraction of the relevant bytes.
401  
402  So, we need a way of specifying which channel to use (the WaveFront
403  only handles mono samples in a given slot), and the only way to do
404  this without using some struct other than wavefront_sample as the
405  interface is the awful hack of using the unused bits in a
406  wavefront_sample:
407  
408  Val Meaning
409  --- -------
410  0 no channel selection (use channel 1, sample is MONO)
411  1 use first channel, and skip one
412  2 use second channel, and skip one
413  3 use third channel, and skip two
414  4 use fourth channel, skip three
415  5 use fifth channel, skip four
416  6 use six channel, skip five
417
418
419  This can handle up to 4 channels, and anyone downloading >4 channels
420  of sample data just to select one of them needs to find some tools
421  like sox ...
422
