/**
 * Native bindings to the ARB_clip_control extension.
 * 
 * This extension provides additional clip control modes to configure how clip space is mapped to window space.  This extension's goal is to 1) allow
 * OpenGL to effectively match Direct3D's coordinate system conventions, and 2) potentially improve the numerical precision of the Z coordinate mapping.
 * 
 * Promoted to core in {@link GL45 OpenGL 4.5}.
