Actually the exporter library took 16-bits-per-channel unsigned shorts
as input, so I had to do some conversion. I took some test files into
cinepaint to make sure I did it right, and it works.
What worries me is whether or not the endian-switching code works; the
dpx/cineon import/export library I took from cinepaint's cineon/dpx
plugin uses tcp/ip endian switching functions, and I frankly have no
idea if the cinepaint developers have made sure it all works or not.
