   *  It is not the intention of the OpenGLFramework to work on a 
   *  global scope! Use this class with caution and seldom even if it is 
   *  convenient! 
   *  Your classes
   *  will develop difficult behavior and will not be transportable outside
   *  a well defined state context! Nevertheless it is usefull to use passive 
   *  components for the 
   *  integration of concepts from the OpenGLFramework into old software.
