/**
* Instantiates a new OpenGL Utility Library object. A GLU object may

* object may only be used when an OpenGL context is current on the
* current thread. Attempts to call most of the methods in the GLU
* library when no OpenGL context is current will cause an exception
* to be thrown.
*
* <P>
*
* The returned GLU object is not guaranteed to be thread-safe and
* should only be used from one thread at a time. Multiple GLU objects
* may be instantiated to be used from different threads
* simultaneously.
