/**
 * 
    
 * Composable pipeline which wraps an underlying {@link GL} implementation,
 * providing error checking after each OpenGL method call. If an error occurs,
 * causes a {@link GLException} to be thrown at exactly the point of failure.
 * 
    
 * 
    
 * Sample code which installs this pipeline:
 * 
     *   gl = drawable.setGL(new DebugGL(drawable.getGL()));
 * 
    
 * For automatic instantiation see {@link GLPipelineFactory#create(String, Class, GL, Object[])}
