/*
 * AIL (Application Intelligence Layer) is a set of per-application controls that influence driver behavior.
 * The primary goal is to improve user experience and/or performance.
 *
 * AIL provides application detection mechanism based on running processes in the system.
 * Mechanism works on Windows and Linux, is flexible and easily extendable to new applications.
 *
 * E.g. AIL can detect running Blender application and enable fp64 emulation on hardware
 * that does not support native fp64.
 *
 * Disclaimer: we should never use this for benchmarking or conformance purposes - this would be cheating.
