Detailed Description
       The SoGLDisplayList class stores and manages OpenGL display lists.

       The TEXTURE_OBJECT type is not directly supported in Coin. We handle
       textures differently in a more flexible class called SoGLImage, which
       also stores some information about the texture used when rendering. Old
       code which use this element should not stop working though. The texture
       object extension will just not be used, and the texture will be stored
       in a display list instead.

Constructor & Destructor Documentation
   SoGLDisplayList::SoGLDisplayList (SoState * state, Type type, int allocnum
       = 1, SbBool mipmaptexobj = FALSE)
       Constructor.

Member Function Documentation
   void SoGLDisplayList::ref (void )
       Increase reference count for this display list/texture object.

   void SoGLDisplayList::unref (SoState * state = NULL)
       Decrease reference count for this instance. When reference count
       reaches 0, the instance is deleted.

   void SoGLDisplayList::open (SoState * state, int index = 0)
       Open this display list/texture object.

   void SoGLDisplayList::close (SoState * state)
       Close this display list/texture object.

   void SoGLDisplayList::call (SoState * state, int index = 0)
       Execute this display list/texture object.

   void SoGLDisplayList::addDependency (SoState * state)
       Create a dependency on the display list.

   SbBool SoGLDisplayList::isMipMapTextureObject (void ) const
       Returns whether the texture object stored in this instance was created
       with mipmap data. This method is an extension versus the Open Inventor
       API.

   SoGLDisplayList::Type SoGLDisplayList::getType (void ) const
       Return type. Display list or texture object.

   int SoGLDisplayList::getNumAllocated (void ) const
       Return number of display lists/texture objects allocated.

   unsigned int SoGLDisplayList::getFirstIndex (void ) const
       Return first GL index for this display list.

   int SoGLDisplayList::getContext (void ) const
       Return an id for the current context.

   void SoGLDisplayList::setTextureTarget (int target)
       Sets the texture object target

   int SoGLDisplayList::getTextureTarget (void ) const
       Returns the texture target
