If libjpeg-turbo is API-compatible with jpeg 8, in what sense does this
game require the former?

Switching everything over to using libjpeg-turbo seems fine. Someone

everything that needs it. Making jpeg (and mozjpeg) install to
non-conflicting locations would also be nice, but can be done separately.
