Three notable clients have all updated libjpeg-turbo.

My goal was to clean things up a bit.  Swizzles are already pretty complicated
(pixel xforms, scaling, subsetting).  And I plan to add color space xforms next.

FWIW, we could also assume support for 565 if we update the Ubuntu CMake.  This
would allow me to clean up more code that I don't like.  But that may be a
little aggressive.

Just moved this code block because it was confusing me as it was.
