Library of Optimized Inner Loops

Liboil is a library of simple functions that are optimized for
various CPUs. These functions are generally loops implementing
simple algorithms, such as converting an array of N integers to
floating-point numbers or multiplying and summing an array of N
numbers. Such functions are candidates for significant
optimization using various techniques, especially by using
extended instructions provided by modern CPUs (Altivec, MMX, SSE,
etc.).

Many multimedia applications and libraries already do similar things
internally. The goal of this project is to consolidate some of the
code used by various multimedia projects, and also make optimizations
easier to use by a broader range of applications.
