/**
 * Native bindings to the SOFT_HRTF extension.
 * 
 * This extension allows an application to request and determine the status of HRTF mixing. HRTF, or Head-Related Transfer Function, is a method of mixing
 * 3D audio for "true" 3D panning, typically using filters designed to simulate how sound is affected by a listener's head as the sound waves travel
 * between the ears.
 * 
 * As a 3D sound API, OpenAL's design allows implementations to transparently render audio using HRTF. However, the OpenAL API currently has no concept of
 * HRTF so there's no way to query if it's being used, and no way for an application to request it on behalf of the user. This aims to fix that.
