16 bpc PNG images were not being written properly when strips were being used. while png_set_swap() is supposed to tell the system to reverse the order of the bits when writing the file, I was unable to get this to work, so I resorted to a brute-force reversal of the bits - but then forgot to put the bits BACK. This is not a problem for single strips, but with multiple strips things get very confused. png_set_swap would make this a non-issue.
