%description
libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors
which uses SIMD instructions (MMX, SSE2, etc.) to accelerate baseline JPEG
compression and decompression.  libjpeg-turbo is generally 2-4x as fast
as the unmodified version of libjpeg, all else being equal.  libjpeg-turbo also
includes a wrapper library for the TurboJPEG API used by VirtualGL and
TurboVNC.

libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but
the TigerVNC and VirtualGL projects made numerous enhancements to the codec,
including improved support for Mac OS X, 64-bit support, support for 32-bit
and big endian pixel formats, accelerated Huffman encoding/decoding, and
various bug fixes.  The goal was to produce a fully open source codec that
could replace the partially closed source TurboJPEG/IPP codec used by VirtualGL
and TurboVNC.  libjpeg-turbo generally performs in the range of 80-120% of
TurboJPEG/IPP.  It is faster in some areas but slower in others.
