Thanks for the suggestion. I considered that when I first adapted my
code to use GIL. At the time I decided not to use them because the
data (as provided by hardware over which I have no control) is
byte-aligned -- there are 12 (or 14) bits of data and 4 (or 2) bits of
padding. I may be misunderstanding bit-aligned images, however.

I will be needing to add bit-aligned pixel types soon, however, and
I'm pleased with how simple that should be.
