/**
 * Native bindings to the EXT_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
 * 
 * 
 * allow OpenGL to effectively match Direct3D's coordinate system conventions, and
 * potentially improve the numerical precision of the Z coordinate mapping.
 * 
 * 
 * This extension is a port of GL_ARB_clip_control to OpenGL ES. For the complete overview of this extension, refer to the "Overview" section of
 * {@code GL_ARB_clip_control}.
