libjpeg-turbo
________________________________________________________________________________

libjpeg-turbo is a fork of libjpeg that uses SIMD instructions to accelerate
baseline JPEG encoding and decoding. Many projects are now using libjpeg-turbo
instead of libjpeg, including popular Linux distributions (Fedora, Debian,
Mageia, openSUSE, ...), Mozilla, and Chrome. Apart from performance, some
projects have chosen to use libjpeg-turbo because it allows them to retain
backward ABI compatibility with the older libjpeg v6b release. libjpeg v7, v8
and v9 broke ABI compatibility with prior releases. [0]
